Filed: 1989-04-10
Abstract: PURPOSE:To acquire enough high withstanding voltage and large current characteristics by realizing longitudinal structure using GaAs. CONSTITUTION:A GaAs insulating gate FET is constituted in a longitudinal structure by forming a first region 3 of n<->GaAs on an n<+>GaAs substrate 2, by forming second regions 4, 5 of p<+>GaAs and p<->GaAs selectively on a surface of the region 3, by forming a third region 6 of n<+>GaAs selectively on the regions 4, 5, and by laminate of CaF2 gate insulating film 7, an AuGe gate electrode 8, etc., on a part of the region 3 and the region 6 and on the region 5 therebetween. According to this constitution, a current flows in a longitudinal direction and an 'on' resistance lowers.
