Method of making a semiconductor device including carbon as a dopant

摘要

While producing a III-V compound semiconductor layer, carbon is added to group III and V elements to control the p type conductivity of the semiconductor layer, forming a p type region. Then, a small amount of n type dopant is added to the group III and V elements together with the carbon to control the n type conductivity of the semiconductor layer, forming an n type region. Therefore, a sharp and precisely-controlled doping profile is obtained in the vicinity of the p-n junction, resulting in a semiconductor device having high initial-performance and high reliability.
