- 論文の詳細を見る
Plasma and ultraviolet (UV) oxidation are used to obtain insulating films for the fabrication of an InP metal-insulator-semiconductor diode. A thin Al film is deposited onto a UV-oxidized n-type InP wafer and the Al film is oxidized with the use of a microwave-excited O_2+N_2 mixture plasma. The depth profile of the composition of the oxidized film is measured by XPS with the aid of Ar ion sputtering. An annealing procedure in N_2-atmosphere followed by H_2-atmosphere annealing was applied to MIS diodes. Resultant InP MIS diodes show excellent C-V characteristics with very small hysteresis. C-V measurements at 1 MHz yield a minimum interface trap density of 6×10^<10> cm^<-2> eV^<-1>.
