Abstract: PURPOSE: To allow functioning as an electric field buffer layer for high breakdown strength, regardless of its semiconductor element is N-type or P-type, relating to formation of semiconductor element in an insulation separation type semiconductor element structure. CONSTITUTION: On a semiconductor substrate 1, a MOS transistor is constituted with a drift layer 5, P-wells 7 and 8, a source 10, a gate 9 and a drain 11, in an island-like area enclosed by insulators 2 and 3.
