Latest Patents

Vipin Joshi holds a patent titled "Doping and trap profile engineering in GaN buffer to maximize AlGaN/GaN HEMT EPI stack breakdown voltage." This invention proposes a set of impurity doping configurations for the GaN buffer in an AlGaN/GaN HEMT device. The goal is to improve the breakdown characteristics of the device. The breakdown characteristics depend on a unique mix of donor and acceptor traps. Using carbon as a dopant increases both donor and acceptor trap concentrations, resulting in a trade-off in breakdown voltage improvement and device performance. A modified silicon and carbon co-doping method is proposed, which enables independent control over donor and acceptor trap concentrations in the buffer. This approach potentially improves the breakdown characteristics of the device without adversely affecting its performance.
