Title: Semiconductor device and its manufacture
Inventor: NAKAYAMA HIDEO
IPC: H01L21/203
Filed: 1996-08-05
Abstract: PROBLEM TO BE SOLVED: To increase the electric resistance between the electrodes of semiconductor devices, forming oxide films with high resistances, by providing each semiconductor device using as its device forming region a compound semiconductor formed via the oxide film which is formed oxidizing an AlGaAs layer or AlAs layer on the surface of a conductive semiconductor substrate. SOLUTION: On a silicon-doped GaAs substrate 1, an AlAs layer 2 and an undoped GaAs layer 3 are laminated. Then, after forming a groove 5 reaching the silicon-doped GaAs substrate 1 by etching, performing the plating processing of the AlAs layer 2 under H2 O at about 420 deg.C, it is oxidized to make it into an oxidized AlAs layer 2. After the lamination of the undoped GaAs layer 3, an electrode 4 for n-side wiring is deposited thereon to form it by etching simultaneously with the formation of the separation groove 5. When the AlAs layer 2 is thermally oxidized under H2 O, an Al2 O3 layer 2 is obtained. Therefore, the electric resistance between the two n-side electrodes 4 can be remarkably increased by the Al2 O3 layer 2 to make a large electric resistance between the electrodes of devices possible, forming oxide films with high resistance.
