Heat treatment is one of the essential and important processes in the semiconductor process. Thermal process is the process of applying thermal energy to a wafer by placing it in an environment filled with a specific gas, including oxidation/diffusion/annealing, etc.

In modern electronics, optoelectronics, microelectronics, and information technology fields, semiconductor substrates and epitaxial technologies are indispensable. They provide a solid foundation for manufacturing high-performance, high-reliability semiconductor devices. As technology continues to advance, semiconductor substrates and epitaxial technologies will also progress, bringing new breakthroughs and developments to the future of the semiconductor industry.

Taiwan's Power Semiconductor Manufacturing Corporation (PSMC) has announced plans to build a 300mm wafer fab in Japan in collaboration with SBI Holdings. The purpose of this collaboration is to strengthen Japan's domestic IC (integrated circuit) supply chain, with a particular focus on circuits for AI edge computing and packaging technologies.

In the process of growing SiC and AlN single crystals by the physical vapor transport method (PVT), components such as the crucible, seed crystal holder and guide ring play a vital role. During the preparation process of SiC, the seed crystal is located in a relatively low temperature region, while the raw material is in a high temperature region exceeding 2400°C. The raw materials decompose at high temperatures to form SiXCy (including Si, SiC₂, Si₂C and other components).

The third-generation wide bandgap semiconductor materials, such as Gallium Nitride (GaN) and Silicon Carbide (SiC), are renowned for their exceptional optoelectronic conversion and microwave signal transmission capabilities. These materials meet the demanding requirements of high-frequency, high-temperature, high-power, and radiation-resistant electronic devices. Therefore, they have vast application prospects in new-generation mobile communications, new energy vehicles, smart grids, and LED technologies. The comprehensive development of the third-generation semiconductor industry urgently requires breakthroughs in key core technologies, continual advancement in device design and innovation, and a resolution to import dependencies.

Plasma Enhanced Chemical Vapor Deposition (PECVD) is a widely used technology in chip manufacturing. It utilizes the kinetic energy of electrons within plasma to activate chemical reactions in the gas phase, thereby achieving thin-film deposition.
