In high-end thin-film deposition processes such as Physical Vapor Deposition (PVD) sputtering, the selection of the target material manufacturing process determines the quality, purity, and microstructural distribution of the thin film. Powder Metallurgy (PM) has emerged as the premier manufacturing technology for producing sputtering targets of refractory metals, brittle alloys, and compound mixtures that cannot be successfully fabricated via traditional cast or melt-metallurgy paths.
By blending ultra-fine, highly-purified metal or ceramic powders and applying heat and pressure below their respective melting points, powder metallurgy ensures absolute control over chemical composition without separation or macro-segregation. This is critical for complex formulations such as WTi (Tungsten-Titanium), WSi (Tungsten Silicide), MoTi (Molybdenum-Titanium), and multi-component oxide ceramics.
Chinese factories represent the absolute vanguard of advanced powder metallurgy and materials refinement, combining raw material vertical integration, large-scale technological investment, and stringent industrial quality controls.
China is home to the world's largest reserves and production capacity for critical target components, including Tungsten (W), Molybdenum (Mo), and Rare Earth Elements. This geographic advantage ensures that Shanghai Creative Advanced Materials Co., Ltd. can source ultra-pure primary powder inputs without geopolitical supply-chain volatility, maintaining stable long-term pricing for global buyers.
We deploy high-capacity Hot Isostatic Pressing (HIP) and vacuum hot pressing systems capable of producing continuous, high-density target bodies up to 300mm in diameter.

Learn More About UsSputtering targets used in microelectronics and optoelectronics require rigorous technical audits prior to production approval. Global procurement officers and thin-film process engineers assess three foundational parameters:
During the sputtering process, targets with coarse or non-uniform grains sputter at varying rates, leading to uneven thickness profiles across the substrate. Through controlled thermomechanical powder metallurgy processing, SCA ensures average grain sizes remain below 100 microns, drastically reducing film thickness deviations and improving productivity.
Interstitially dissolved oxygen within sputtering targets deteriorates electrical performance, causing undesirable shifts in resistivity and lowering optical transmission. We perform target sintering inside ultra-high vacuum environments and high-purity inert gas chambers, ensuring oxygen levels are consistently maintained below 500 ppm for alloy systems, and even lower for premium refractory metals.
Refractory and ceramic targets suffer from thermal stress during deposition. Our state-of-the-art backing plate bonding facility applies pure Indium or elastomeric bonds with a guaranteed void-free rate above 98% (verified by non-destructive ultrasonic C-scan). This ensures uniform heat dissipation and protects the target from cracking under high power density.
Powder metallurgy targets are critical enablers for numerous technology sectors. Below are the key applications where SCA's target solutions drive industrial growth.
Our WTi and WSi targets are essential for forming diffusion barrier layers and gate contacts in integrated circuits. The 300mm WTi target prevents chemical interaction between aluminum/copper tracks and silicon layers, guaranteeing high device durability and performance.
High-conductivity thin films are critical for liquid crystal displays (LCD) and organic light-emitting diode (OLED) systems. We supply Molybdenum and Chromium targets processed to minimize particle emission during the PVD cycle, which drastically reduces pixel defect rates.
The efficiency of CIGS (Copper Indium Gallium Selenide) and silicon-based solar panels relies heavily on the contact layer. SCA's molybdenum targets and zinc-oxide-doped variations optimize electrical conductivity and solar absorption profiles.
For cutting tools, industrial molds, and consumer electronics casings, PVD hard coatings (such as TiAlN and CrN) are applied for mechanical protection. Our Boron Carbide, CrSi, and MoTi targets supply high hardness, thermal stability, and corrosion protection.
We control the synthesis of premium ceramic and metallic materials to guarantee microstructural integrity across four core compound categories.
Boron Carbide (B₄C) ranks among the hardest synthetic structures on Earth, second only to diamond and cubic boron nitride. Beyond its high abrasion and scratch protection attributes, Boron Carbide plays a central role in nuclear engineering due to its high neutron absorption cross-section. Sintered via advanced hot-pressing pathways, our B₄C compounds are widely applied in lightweight military vehicle plating, wear-resistant nozzles, and shielding in clean-energy installations.

The manufacturing sector for sputtering targets is undergoing deep technological shifts driven by semiconductor scaling and green energy growth. Key industry developments include:
Modern sub-5nm microchip logic nodes require target materials free of alkali metal and radioactive impurities. The target industry is investing in complex chemical purification loops to reduce impurity limits to parts-per-billion (ppb) levels.
New multi-element alloy layers containing combinations of five or more elements are being engineered for advanced gate stack applications. Powder metallurgy remains the primary fabrication method capable of blending these complex elements uniformly.
To reduce waste and limit environmental impact, factories are establishing recycling programs to recover high-value metals like Tungsten, Ruthenium, and Tantalum directly from spent backing plates.
Powder metallurgy targets must adapt to higher sputtering power densities, demanding better thermal management and microstructural stability.
Our research and development division focuses on refining powder grain shapes, reducing internal stress, and creating composite targets that prevent delamination at higher operational temperatures.
Through partnerships with research centers and university material laboratories, SCA is engineering next-generation composite and metal targets that meet these industrial requirements.
