Abstract: PURPOSE:To improve the degree of integration and operating speed, by sequentially depositing an oxidation resisting layer 3 and an injection blocking layer 4 only on the operation region of a substrate after patterning, and carrying out the succeeding processes by the self-alignment with said patterned layers. CONSTITUTION:With an injection blocking layer 4 as a mask, an embedded insulating layer 14 is formed by ion implantation. A base contact layer 15 is formed by doping impurities having the same conducting type as a base region in high concentration on a semiconductor substrate 1 on the layer 14. A field oxide film 5 is formed by thermal oxidation with an oxidation resisting layer 3 as a mask. The oxidation resisting layer 3 is removed. An opening part 6 is formed in the field oxide film 5. Impurities are introduced through the opening part and an inner base region 16 is formed. Then, impurities are introduced through the opening part 6, and an emitter region 17 is formed. Only by using one photomask as described above, said five processes are carried out by self- alignment. Thus, the base contact layer 15 can be taken out of the side wall of the inner base region 16, and the base region can be made as small as possible.
