Patent number: 9660068Abstract: According to this GaN-based HFET, resistivity ? of a semi-insulating film forming a gate insulating film is 3.9×109?cm. The value of this resistivity ? is a value derived when the current density is 6.25×10?4 (A/cm2). By inclusion of the gate insulating film by a semi-insulating film having a resistivity ?=3.9×109?cm, a withstand voltage of 1000 V can be obtained. Meanwhile, the withstand voltage abruptly drops as the resistivity of the gate insulating film exceeds 1 ×1011?cm, and the gate leak current increases when the resistivity of the gate insulating film drops below 1 ×107?cm.Type: GrantFiled: September 1, 2014Date of Patent: May 23, 2017Assignee: SHARP KABUSHIKI KAISHAInventors: Yushi Inoue, Atsushi Ogawa, Nobuyuki Ito, Nobuaki Teraguchi
