Abstract: PURPOSE:To enable to readily form a complementary semiconductor element by forming an island of a uniconductive single crystal silicon as an island of single crystal silicon having two types of conductivities, and forming the single crystal in the vicinity of a dielectric film in a high density buried layer having the same conductivity as the single crystal of the island. CONSTITUTION:A dielectric isolating substrate 12 which has an island 11 of a plurality of single crystal silicon islands 11 including a high density buried layer 10 having the same conductivity only in the island except a region to be formed in a conductive island of different type in a sole conductive type insulated from each other through an insulating oxidized film 9 is provided in a polycrystalline silicon 8. A p type conductive island which does not contain a necessary p type high density buried layer of n type conductivity is formed by selectively etching method with slots 14 with an oxidized film 13 as a mask.
