Then both film 3 and layer 2 of about 1500Å are etched away via Si 3 N 4  mask 4. Film 3 prevents both the contamination and distortion. The substrate and the weighed water are put into the quartz capsule and then sealed up hermetically with the inner pressure of several torrs with heating. As a result, layer 2 of the field region is converted to SiO 2 5 up to substrate 1. Then mask 4 and film 3 on island-shaped layer 2 are removed, and then gate oxide film 6 and CVD poly Si7 are laminated to then carry out the photoetching. Then As ion is injected along with the heat treatment to change n + -layer 8 and 9 plus layer 7 into conductive state. And PSG10 is coated with the window drilled selectively, and then Al wiring 11 is provided. With this method, an excessive leak never causes even with the SOS device which has been through with the selective oxidation.
