Title: Compound semiconductor device
Inventor: HIKOSAKA YASUMI
IPC: H01L29/872
Filed: 1982-12-29
Abstract: PURPOSE:To change an electron barrier potential between a Schottky barrier and an energy gap in an adjusting layer arbitarily, by stacking a P type AlyGa1-yAs barrier adjusting layer on an N type AlxGa1-xAs electron donating layer. CONSTITUTION:On a non-added GaAs substrate 14, N type AlxGa1-xAs 13 and P type AlyGa1-yAs 12 are stacked, and a Schottky metal gate electrode 11 is attached. A numeral 15 indicates a secondary electron gas layer. A potential barrier, which is yielded at this time, is changed by the thickness of the P layer 12, the doped amount of the P layer, and the value of (y). The potential can be selectively adjusted from the minimum value of a conventional Schottky barrier phis 0.8eV to the maximum value of a forbidden band width Eg 2.1eV and its neighborhood. Therefore, the forward voltage in the gate electrode can be dramatically increased. the relationship between the thickness (t) of the layer 12 and the amount of doping Na is computed as specified by the expression: where (y) is constant and equal to (x) in the N type AlxGa1-xAs electron donating layer 13 (amount of doping ND). Furthermore, when a grade is imparted to the Al distribution of the layer 12 and terminated at y=0 (GaAs) on the surface, it is effective in preventing oxidation of the surface.
