Abstract

PURPOSE: The surface of the semiconductor device is covered with lamination coat which uses Al2O3 film for the lower layer and SiO2 film for the upper layer respectively. And Al2O3 thick film of the region reaching between the substrate circumference sections from the area near vamp terminal is made thickner than Al2O3 film at internal circuit wiring region. Furthermore, the upper part of vamp terminal is made to expose Al2O3 film. In this way, the life of the semiconductor device can be extended.
