Abstract

A semiconductor chip mount structure includes a substrate having a base surface on which base side connectors are formed; a semiconductor chip mounted on the base surface, the semiconductor chip having chip side connectors on a first surface thereof facing the base surface, the chip side connectors being electrically connected to the base side connectors; an insulating resin layer covering the chip side connectors and the base side connectors; a metal layer, made of a metal having a melting point lower than a temperature at which the electrical components of the semiconductor chip may be thermally destroyed, for covering the semiconductor chip and the insulating resin layer; and a wetting characteristic improving layer such as a metal powder or foil layer, formed along a contact surface between the metal layer and the insulation resin layer.
