Abstract
PURPOSE: In a semiconductor integrated circuit device with a selective oxide film which is composed of a silicon nitride film on a minus conduction type semiconductor substrate, to reduce the area of a circuit by oxidating the whole domain divided by the selective oxide film.
CONSTITUTION: An n-type impurity layer 102 is formed by diffusing P on a p-type Si substrate 101, on which is coated a SiO2 film 103 and moreover on which a Si3N4 film 104 is allowed to grow. Then a Si3N4 film 104 and a SiO2 film 103 are etched masking photoresist 105. Then B is diffused masking the Si3N4 film 104, etc. and a p+-type diffusion layer 106 is formed. After that, heat treatment is carried out until the whole n-type diffusion layer is covered with a SiO2 film 107. The Si3N4 film 104 is removed at last.
