Abstract

A heat resisting resin sheet is bonded to a semiconductor chip as a protective cap for protecting a beam structure provided on the semiconductor chip, through a heat resisting adhesive. The heat resisting resin sheet is composed of a polyimide base member and the heat resisting adhesive is composed of silicone adhesive. The heat resisting resin sheet is not deformed during a manufacturing process of the semiconductor chip. In addition, grinding water does not invade into the semiconductor chip during dicing-cut.
