Patent JP-S57120376-A (JP)
Title: Manufacture of gaas ic
Inventor: TOYODA NOBUYUKI
IPC: H01L29/47
Filed: 1981-01-20
Abstract: PURPOSE:To obtain a stable threshold voltage by performing a threshold voltage adjustment process after completing inter-elemental wiring process and by completely reacting deposited metal. CONSTITUTION:If threshold voltage adjustment is performed right after vapor depositing of a metal, heating processes in inter-elemental wiring process and inter-insulation film forming process cause the adjusted threshold voltage to change as a result of the reaction of the unreacted metal with GaAs. The threshold voltage adjustment at the final process after inter-elemental wiring process makes only a slight change of the threshold voltage. However, even by this process, a large amount of unreacted metal may cause flactuation in the threshold voltage. The amount of the metal is preferably as small as possible and the metal must be reacted completely with GaAs.
