Conductive hardening resin for a semiconductor device and semiconductor device using the same

Abstract

Conductive hardening resin for a semiconductor device of the present invention contains metal powder for providing electric conduction between electrodes positioned on the front of a semiconductor chip and a wiring material including lead terminals via a conductive plate. The resin has a modulus of elasticity of 2.0×109 Pa or below when hardened. The resin prevents the contact resistance of the metal plate, lead terminals and semiconductor chip from increasing in the event of temperature cycling tests and a pressure cooker tests. Further, the resin frees the metal plate and chip from peel-off and corrosion, respectively.
