Abstract
PURPOSE: To increase the integration for IC, by minimizing the size of the base window, through the coverage of the surrounding wall of the base window formed on the first insulating film with the protective film not immersed with etching, in providing the emitter window to the first and second insulating films coated on the semiconductor substrate.
