    摘要: There is embodied a high-reliability high-voltage resistance compound semiconductor device capable of improving the speed of device operation, being high in avalanche resistance, being resistant to surges, eliminating the need to connect any external diodes when applied to, for example, an inverter circuit, and achieving stable operation even if holes are produced, in addition to alleviating the concentration of electric fields on a gate electrode and thereby realizing a further improvement in voltage resistance. A gate electrode is formed so as to fill an electrode recess formed in a structure of stacked compound semiconductors with an electrode material through a gate insulation film, and a field plate recess formed in the structure of stacked compound semiconductors is filled with a p-type semiconductor, thereby forming a field plate the p-type semiconductor layer of which has contact with the structure of stacked compound semiconductors.
