Abstract

A new device structure with four epitaxial layers and a recessed gate is proposed for normally-off operation in GaN-FETs. Employment of this structure makes it possible to control accurately the threshold voltage without accurate control of recess etching depth. The high breakdown voltage and the low on-resistance of the fabricated devices are also reported.
