Abstract
In a semiconductor apparatus and method for producing the same where an upper surface of a semiconductor chip having a thick film electrode is coated with a passivation film, the semiconductor chip being molded with a resin mold such as a power SIT, a conductive film made of a doped polysilicon, a metal material, or the like and which has a thickness of for example 3000 angstroms or more is circumferentially disposed from a bottom circumference of the thick film electrode to a part of region between a field oxide film and a passivation film so as to effectively prevent cracks in the passivation film caused by a cyclic temperature test from extending into the field oxide film.
