Ion Implant and Diffusion Process

Ion implantation is a method of semiconductor doping and one of the main processes in semiconductor manufacturing.

Challenges of Ion Implantation Technology in SiC and GaN Power Devices

Wide bandgap (WBG) semiconductors such as Silicon Carbide (SiC) and Gallium Nitride (GaN) are expected to play an increasingly important role in power electronic devices. They offer several advantages over traditional Silicon (Si) devices, including higher efficiency, power density, and switching fr......

Various applications of quartz in semiconductor manufacturing

At first glance, quartz (SiO2) material looks very similar to glass, but what is special is that ordinary glass is composed of many components (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.), while quartz only contains SiO2, and its microstruct......

Understanding the Complete Semiconductor Device Fabrication Process

The fabrication of semiconductor devices primarily encompasses four types of processes: (1) Photolithography (2) Doping Techniques (3) Film Deposition (4) Etching Techniques The specific techniques involved include photolithography, ion implantation, rapid thermal processing (RTP), plasma-enha......

Difficulty in preparing SiC substrates

At present, the most important direction trend of substrate development is to expand the diameter. The 6-inch mass production line in the global SiC market is maturing, and leading companies have entered the 8-inch market.

Silicon Carbide Substrate

The process of silicon carbide substrate is complex and difficult to manufacture. SiC substrate occupies the main value of the industry chain, accounting for 47%. It is expected that with the expansion of production capacity and the improvement of yield in the future, it is expected to drop to 30%.
