Abstract
PURPOSE: To economically form a diffusion layer whose depth and layer resistance at the specified positions and other portions vary, by forming a thin polycrystalline semiconductor film of a reverse conductivity type in the specified position on the selectively exposed surface of a semiconductor substrate of - conductivity type and diffusing an impurity from the thin polycrystalline film through heat treatment in a non-oxidizing atmosphere.
