Abstract
A semi-conductor device in which a semi-conductor element is sealed with a molding resin is disclosed. In the device, adhesion between a semi-conductor chip and the molding resin is achieved mainly by oxygen-crosslinking between silicon in the semi-conductor chip and silicon in the molding resin. The device exhibits excellent moisture-resistant reliability even after mounting.
