In recent years, large coating companies in Asia (China, Japan, South Korea, India, etc.) have been accelerating their transformation, gradually abandoning in-house grinding pigment paste with machines line, and instead directly purchasing Pigment Dispersions such as CAB pigment chips, water based solid pigment dispersion. This trend is driven by multiple factors, including cost, efficiency, environmental protection, and technology.

In the past, paint manufacturers typically sourced their own materials and purchased sand mills lines for grinding themselves. However, this approach often resulted in suboptimal formulations. Additionally, due to outdated machinery, issues such as machine blockages and color changes during disassembly can lead to material wastage. For example, a 30-ton capacity sand mill can cause an average of 5-10 kilograms of wastage, and during color changes, rinsing can result in wastage rates as high as 5%-10% when grinding 200-300 kilograms. Many manufacturers previously did not consider material wastage, labor costs, or inventory costs, focusing solely on raw material costs. The more inventory is held in the warehouse, the greater the consumption of workshop logistics, as well as the higher the costs associated with space, labor, and inventory. Additionally, while paint factory engineers are highly skilled in paint formulations, they have not conducted in-depth research into the chemical structure, colorfastness, heat resistance, color bleeding, and environmental performance of organic pigments. Relying solely on paint factories to resolve issues related to color paste stability and compatibility presents significant challenges.

As a result, several Asian paint manufacturers have gradually abandoned in-house color paste production and shifted to purchasing finished color paste. According to Nippon Paint's 2023 annual report, since closing its color paste production lines in 2022, production costs have decreased by 18%, and delivery cycles have been shortened by 40%. Asia Coatings also stated that since purchasing ready-made color pastes, the development cycle for new products has been reduced from three months to one month, significantly improving production efficiency.

Compared to self-grinding color paste, purchasing finished color paste or pigment dispersion to solve pigment paste directly has the following advantages:

Can we continue to supply high-quality products and services? Can we solve fundamental problems faced by customers, such as stability and compatibility? How can we help customers solve problems such as environmental protection, inventory backlogs, and excessive standards? China AAB Group thought about this early on and put it into practice.

In the semiconductor manufacturing industry, temperature control is a critical factor determining product yield. Processes such as thin film deposition and etching require precise temperature control for wafers, where temperature uniformity directly influences chip performance and reliability. Within this precision-driven process, aluminum nitride (AlN) ceramic heaters have emerged as an indispensable core component in semiconductor equipment, thanks to their outstanding performance.

Why Have Ceramic Heaters Become the Preferred Choice in Semiconductor Manufacturing?

The semiconductor process environment is extremely harsh—characterized by high vacuum, plasma, and the presence of corrosive chemical gases, which impose stringent requirements on heater materials. Traditional metal heaters find it difficult to operate reliably long-term under such conditions. In contrast, ceramic heaters, with their exceptional corrosion resistance, high electrical insulation, and thermal stability, have become the sole solution capable of fulfilling this role.

AlN ceramic heaters are installed directly inside the process chamber in close contact with the wafer. They not only support the wafer but also ensure it attains a stable and uniform process temperature, acting as the "heart" of thin film deposition equipment.

Aluminum Nitride: The Ideal Material for Ceramic Heaters

Among various ceramic materials, aluminum nitride (AlN) stands out as the optimal choice for ceramic heaters, owing to its unique combination of properties:

Excellent Thermal Conductivity

AlN boasts a theoretical thermal conductivity as high as 320 W·m⁻¹·K⁻¹. This property allows the heater to achieve rapid heating and cooling, significantly enhancing the efficiency of semiconductor manufacturing processes.

Perfect Thermal Expansion Match

The coefficient of thermal expansion of AlN (4.18×10⁻⁶ K⁻¹) closely matches that of silicon. This compatibility is crucial, as it effectively minimizes thermal stress on the wafer, directly improving product yield.

Outstanding Mechanical and Electrical Properties

AlN combines high mechanical strength, excellent wear resistance, and outstanding electrical insulation (with a volume resistivity up to 10¹³ Ω·cm), alongside low dielectric loss. This comprehensive profile fully meets the demanding material requirements of semiconductor processes.

Environmental and Safety Benefits

Unlike toxic materials such as beryllium oxide, aluminum nitride is non-toxic and environmentally friendly, aligning better with the sustainable development philosophy of modern industry.

Precision Structure and Manufacturing Process

The structural design of AlN ceramic heaters is highly sophisticated:

Ceramic Base: Carries the wafer and integrates internal heating elements and RF electrodes.

Support Structure: Utilizes ceramic materials with a matched coefficient of thermal expansion to safeguard terminals and leads.

Unique Shaft Joint: Effectively withstands erosion from plasma and chemical gases.

Internal Flow Channels: Ensure even temperature distribution across the heater.

In terms of manufacturing, advanced screen printing technology is employed, using conductor pastes such as tungsten, molybdenum, or tantalum to form precise circuit patterns.

The 5G and AI computing revolution is confronting a core contradiction in optical modules: heat dissipation versus high-frequency transmission. When 1.6T optical modules overheat, causing a potential 30% drop in computing power, aluminum nitride (AlN) ceramics emerge as a critical solution with their exceptional properties.

I. Material Breakthrough: From "Overheating" to "Cool Operation"

AlN ceramics boast a thermal conductivity of up to 170 W/(m·K), approximately eight times that of traditional alumina. This enables limiting the temperature rise of 1.6T optical module chips to within 5°C even under full load. Utilizing a "multilayer co-firing + thin-film wiring" process, it achieves surface line widths as fine as 20μm, reducing signal loss by over 50% in the 100GHz frequency band compared to conventional thick-film processes. Furthermore, it supports 50μm pitch gold wire bonding, perfectly meeting high-density packaging requirements.

Compared to traditional materials, AlN ceramics offer significant comprehensive advantages: superior thermal conductivity to alumina, safer and non-toxic compared to beryllium oxide (BeO), and better suitability for high-frequency transmission than silicon nitride. This makes AlN a key enabler for the miniaturization and enhanced performance of communication equipment.

II. Industrialization: Driven by Policy and Technology

Supported by China's "14th Five-Year Plan" for New Materials Development, the domestic AlN market is projected to reach ¥12 billion by 2025 and exceed ¥20 billion by 2030.

Technological breakthroughs are enabling mass production. Batch shipments of AlN multilayer thin-thick film technology have been achieved, with Physical Vapor Deposition (PVD) and other advanced manufacturing techniques reaching yields over 90%. Consequently, the unit cost of high-performance AlN materials has dropped by 40% compared to five years ago. In practical AI data center applications, 400G/800G optical modules equipped with AlN substrates maintain stable operation even in non-cooled environments, providing crucial material support for the evolution from 800G to 1.6T.

III. Reshaping the Industry: From Material Breakthrough to Ecosystem Transformation

AlN ceramics are altering the competitive landscape, aiding Chinese companies in achieving breakthroughs in cutting-edge areas like 1.6T. Its applications are expanding beyond communications into new energy vehicles, aerospace, and more. Annual demand from the new energy vehicle sector alone is forecasted to surpass 1 million tons by 2030.

This material innovation is fostering new design philosophies. With heat dissipation less of a constraint, optical modules using AlN substrates can achieve 30% higher power density within the same volume, potentially reducing data center footprint by nearly a quarter.

As 5G deployment accelerates and 6G R&D progresses, the strategic importance of AlN ceramics becomes increasingly evident.

In the pursuit of miniaturized and high-performance electronic devices, thermal pads serve as silent guardians. They fill gaps, establish efficient heat conduction channels, and shoulder multiple responsibilities including insulation, shock absorption, and sealing. However, the often-unavoidable aging of traditional thermal pads after long-term use has become a potential threat to the long-term reliability of equipment.

When your device experiences performance degradation, abnormal shutdowns, or a shortened lifespan, the root cause may very well lie with a thermal pad that has aged.

The Aging Pains of Traditional Thermal Pads:

Increased Hardness & Reduced Elasticity: Under the continuous influence of heat and stress, the internal polymer structure of the pad changes, leading to increased cross-linking and the material becoming hard and brittle. This prevents it from conforming closely to surfaces, causing a dramatic increase in contact thermal resistance and a sharp drop in heat dissipation efficiency.

Permanent Decline in Thermal Conductivity: Aging destroys the microscopic thermal pathways within the pad. Thermal fillers can agglomerate, and the polymer matrix can degrade. These defects collectively increase thermal resistance, causing a significant衰退 in the pad's core function – its thermal conductivity.

Deterioration in Physical Form: You might observe the pad cracking, powdering, or even exuding silicone oil onto its surface. These are not just signs of performance failure; they can also contaminate surrounding components, posing secondary risks like short circuits.

So, how can we fundamentally address these challenges?

The answer lies in innovation at the material source – adopting advanced thermal pads that use Aluminum Nitride (AlN) as the core filler.

Aluminum Nitride is not merely a simple filler alternative; it is a functional ceramic material capable of redefining the performance and longevity boundaries of thermal pads. Here's how it precisely solves the aforementioned aging problems:

1. Combats Hardening, Preserves Lasting Softness & Compliance

Aluminum Nitride filler offers excellent thermal stability and chemical inertness. It does not react adversely with the polymer matrix, inhibiting the hardening problem caused by excessive cross-linking at its fundamental level. This means that pads using Aluminum Nitride filler can maintain excellent softness and resilience even under long-term high-temperature environments, ensuring consistent, intimate contact with the thermal interface, thereby stably maintaining low contact thermal resistance.

2. Stable Thermal Conductivity, Rejects Performance Decay

This is a core advantage of Aluminum Nitride. Firstly, it possesses an inherently high thermal conductivity, easily constructing efficient three-dimensional thermal networks. More importantly, its robust crystal structure remains stable even during long-term high-temperature aging, effectively preventing the structural degradation of the thermal pathways. Both the agglomeration of fillers and the degradation of the matrix are significantly suppressed, thereby ensuring the long-term stability of the thermal conductivity throughout the product's entire lifecycle and preventing performance from silently declining.

3. Reinforces Structure, Prevents Cracking & Oil Bleed

Aluminum Nitride filler exhibits good compatibility with polymer matrices like silicone. This stable composite structure can greatly reduce the bleeding of small molecules such as silicone oil, avoiding contamination and performance loss due to oil separation at the source. Simultaneously, its reinforcing effect grants the pad greater resistance to tearing and fatigue, enabling it to withstand the stresses from thermal cycling more effectively and significantly reducing the risk of cracking and powdering.

Conclusion

Choosing a thermal pad is not just about selecting an initial specification; it is about making a long-term reliability commitment for your product. Using Aluminum Nitride as a strategic filler is no longer a simple material upgrade, but a fundamental innovation targeting the aging pains of traditional thermal pads.

Among the various forming processes for aluminum nitride (AlN) ceramics, traditional methods such as die pressing, hot pressing, and isostatic pressing are well-established but face several challenges. Due to the strong hydrophilicity of AlN powder, contact with water should be minimized during the forming process to avoid oxidation that could compromise material performance. Although hot pressing and isostatic pressing can produce high-performance bulk materials, their high cost and low efficiency make it difficult to meet the ever-growing demand for AlN ceramic substrates in the electronics industry. Against this backdrop, tape casting technology has gradually emerged as a mainstream process for manufacturing aluminum nitride ceramics in electronics.

How Does Tape Casting Prepare Multilayer Aluminum Nitride Ceramics?

The core of this technology lies in mixing aluminum nitride powder with sintering aids, binders, and solvents to form a homogeneous slurry, which is then cast into thin green sheets using a tape caster. Subsequently, these sheets undergo processes such as punching, drilling, metal pattern printing, stacking, and lamination to form multilayer ceramic green bodies. Finally, after high-temperature binder burnout and sintering in a nitrogen atmosphere, dense and high-performance multilayer aluminum nitride ceramics are produced. This process is not only efficient but also particularly suitable for the large-scale production of ceramic substrates.

Process Details Determine Final Performance

The properties of AlN ceramic substrates prepared by tape casting are closely related to multiple process parameters: powder quality, casting parameters, binder burnout, and sintering regimes all require meticulous control. For example, coarser powders are easier to form but struggle to achieve high-quality substrates, while finer powders, though more challenging to process under strictly controlled conditions, often yield superior product quality. The binder burnout process must be gentle and stable, as excessively high temperatures or rapid heating rates can easily cause cracking in the green body. The sintering regime is even more critical, directly determining the final properties of the ceramic, such as thermal conductivity and strength.

Currently, tape casting systems are mainly divided into organic-based and water-based systems. Organic systems face environmental pressure due to the use of toxic solvents, while water-based systems, though environmentally friendly, still require further refinement in drying technology, representing an important direction for future development. For instance, research using a mixed solvent of ethanol and isopropanol has successfully prepared AlN ceramics with a thermal conductivity of 178 W/(m·K), demonstrating the potential of non-aqueous solvent systems.

Conclusion

Tape casting technology, with its advantages of high efficiency, consistent quality, and suitability for mass production, has become an indispensable part of aluminum nitride ceramic substrate manufacturing. As environmental requirements become more stringent and product forms diversify, this technology continues to evolve. Together with other forming processes, it drives the broader application of aluminum nitride ceramics in fields such as electronic packaging and heat dissipation components.

With the rapid advancement of microelectronics technology, there is an increasingly urgent market demand for ceramic components that offer high thermal conductivity, miniaturization, and complex shapes. While the traditional tape casting process is efficient and yields stable products, it often falls short when confronting intricate three-dimensional structures. It is precisely this challenge that has propelled Powder Injection Molding (PIM) technology to the forefront of the industry, becoming the key breakthrough for manufacturing high-precision, complex-shaped aluminum nitride ceramics.

Why Choose Powder Injection Molding?

Powder Injection Molding is an advanced process that merges modern plastic injection molding with powder metallurgy. Its core advantage lies in "near-net-shape forming"—it can directly produce components with intricate structures and complex geometries. Due to the flow state during mold filling, the material uniformly fills the mold cavity with minimal die wall friction. This results in green bodies with highly uniform density and exceptional dimensional accuracy. Internationally, this technology is regarded as a significant innovation in the field of component manufacturing for the 21st century.

The Key to Success: Binder and Feedstock System

The core of this technology lies in the binder system. The binder not only acts as a carrier for the powder, determining the material's fluidity and injection properties, but must also maintain the shape of the green body during the critical debinding process. To meet these dual requirements, modern binders are typically scientifically formulated from multiple organic components.

Simultaneously, the rheological properties of the feedstock system are paramount. An ideal system requires low viscosity, high strength, and good thermal stability. During processing, balancing temperature and fluidity is crucial: excessive temperature can lead to decomposition and pore formation, while insufficient temperature results in poor fluidity and incomplete mold filling.

Process Details Determine Success or Failure

Injection Pressure: Requires precise control. Insufficient pressure can lead to incomplete filling; excessive pressure introduces internal stress, causing demolding difficulties or cracking and deformation of the green body.

Injection Speed: Also requires optimization. Speed that is too slow allows the material to cool prematurely, preventing complete filling. Speed that is too fast can cause jetting, phase separation, and the formation of surface defects.

Therefore, by comprehensively optimizing various injection parameters, structurally sound and high-performance aluminum nitride ceramic green bodies can be successfully prepared.

Looking to the Future

Powder Injection Molding not only solves the manufacturing challenges of complex-shaped AlN ceramics but also provides the material realization possibilities for innovative designs in fields such as electronic thermal management, semiconductor packaging, and high-frequency devices. As the technology continues to mature, it is driving the rapid development of high-thermal-conductivity ceramic components towards greater miniaturization, higher integration, and enhanced performance.

First, the manufacturing process is extremely challenging.

To achieve high-performance AlN powder, ultra-high-purity raw materials are required, followed by sintering in a high-temperature (above 1800°C) inert atmosphere, which consumes significant energy. The powder is prone to oxidation, and achieving dense sintering is difficult. Special additives must be used, and the process requires precise control, as any defect can cause a sharp decline in key properties such as thermal conductivity. This results in high production barriers and low yield. Moreover, precision machining adds to the cost: with a Mohs hardness of 8–9, AlN’s brittleness makes cutting and drilling prone to chipping and microcracking, leading to low processing yield, rapid tool wear, and high machining costs. Ensuring consistency in mass production remains a major challenge.

Second, its performance is irreplaceable.

AlN combines excellent thermal conductivity (about 10 times that of alumina), a thermal expansion coefficient matching that of silicon, and outstanding electrical insulation. This makes it an indispensable material for heat dissipation substrates and critical packaging in 5G communications, high-power LEDs, aerospace electronics, and next-generation semiconductor packaging. These high-end applications demand exceptional reliability and are less price-sensitive.

Finally, the market is highly concentrated.

The global high-end AlN market has long been dominated by a few Japanese and American companies. Technological barriers limit supply, creating tension in availability. Additionally, AlN is a "small yet critical" strategic material. Its overall demand remains relatively low, making it difficult to achieve significant cost reductions through economies of scale. Amid the current trend toward semiconductor industry self-sufficiency, its strategic importance has further increased, keeping prices high.
