Abstract

PURPOSE: To avoid the disconnection steps by depositing a photosensitive and soluble layer onto a wiring metallic layer and exposing the first layer to light plural times to remove the exposed portion by dissolution; the metallic layer being etched using a mask at each removal process to form the steps at its both ends.
