The semiconductor industry is witnessing unprecedented growth, especially in the realm of silicon carbide (SiC) power electronics. With many large-scale wafer fabs undergoing construction or expansion to meet the surging demand for SiC devices in electric vehicles, this boom presents remarkable opportunities for profit growth. However, it also brings forth unique challenges that demand innovative solutions.
At the heart of increasing global SiC chip production lies the manufacturing of high-quality SiC crystals, wafers, and epitaxial layers. Here, semiconductor-grade graphite materials play a pivotal role, facilitating SiC crystal growth and the deposition of SiC epitaxial layers. Graphite's thermal insulation and inertness make it a preferred material, extensively used in crucibles, pedestals, planetary disks, and satellites within crystal growth and epitaxy systems. Nevertheless, the harsh process conditions pose a significant challenge, leading to rapid degradation of graphite components and subsequently hindering the production of high-quality SiC crystals and epitaxial layers.
The production of silicon carbide crystals entails extremely harsh process conditions, including temperatures exceeding 2000°C and highly corrosive gas substances. This often results in the complete corrosion of graphite crucibles after several process cycles, thereby escalating production costs. Additionally, the harsh conditions alter the surface properties of graphite components, compromising the repeatability and stability of the production process.
To combat these challenges effectively, protective coating technology has emerged as a game-changer. Protective coatings based on tantalum carbide (TaC) have been introduced to address the issues of graphite component degradation and graphite supply shortages. TaC materials exhibit a melting temperature exceeding 3800°C and exceptional chemical resistance. Leveraging chemical vapor deposition (CVD) technology, TaC coatings with a thickness of up to 35 millimeters can be seamlessly deposited on graphite components. This protective layer not only enhances material stability but also significantly extends the lifespan of graphite components, consequently reducing production costs and enhancing operational efficiency.
