摘要
This paper describes the performance of AIGaN/GaN HEMTs with 2.4μm source-drain spacing. So far these are the smallest source-drain spacing AIGaN/GaN HEMTs which have been implemented with a domestic wafer and domestic process. This paper also compares their performance with that of 4μm source-drain spacing devices. The former exhibit higher drain current, higher gain, and higher efficiency. It is especially significant that the maximum frequency of oscillation noticeably increased.
