EPi — Investor Relations & Filings
Episil-Precision Inc. is a specialized manufacturer of epitaxial wafers, focusing on the development and production of silicon and compound semiconductor materials. The company utilizes advanced Metal Organic Chemical Vapor Deposition (MOCVD) technology to provide GaN-on-Si epitaxial processes, incorporating proprietary AlGaN and GaN composite buffer layers. This technical approach mitigates stress between GaN and silicon substrates, minimizing wafer defects while ensuring high device performance and reliability. Its product portfolio includes mass-produced 8-inch GaN-on-Si epitaxial wafers (100V to 600V) and Silicon Carbide (SiC) epitaxial solutions. By integrating expertise in both GaN and SiC technologies, the company serves the evolving requirements of power devices, electric vehicles, and AI infrastructure.
