Abstract

PURPOSE:To eliminate the pitch displacement between the electrode pattern and the semiconductor device by covering an insulating film on one conductivity type region, simultaneously forming windows for mounting electrode terminal and for forming reverse conductivity type region when opening both the windows and then diffusing the reverse conductivity type region. CONSTITUTION:An N type layer 2 is epitaxially grown on an N type Si substrate 1, a P type region 3 is diffused therein, and an SiO2 film is covered on the entire surface including the region 3. Then, the windows 5 and 6 for mounting the electrode terminal on the film 4 and for diffusing the N type region 11 are simultaneously opened on the region 3, an SiO2 film 7 and an Si3N4 film 8 are laminated on the entire surface thereof. Thereafter, the laminated film on the window 6 is removed by etching it with the photoresist film as a mask, an SiO2 film 10 is covered on the bottom surface and the side walls in the window 6, ions are injected thereto, and it is heat treated, and an N type region 11 is thus formed in the region 11. Subsequently, the films 7, 8 are removed, and the window 5 thus formed previously is exposed.
