Patent ID: 8142602

Claim:
A method of forming a mounted structure, comprising the steps of: providing a semiconductor device on a substrate with an intermediary of a bonding material, the semiconductor device including: an electrode; a protective layer on the electrode and having an opening exposing a portion of the electrode; a resin convexity protruding higher than the electrode, the resin convexity being laterally spaced apart from the opening of the protective layer; and a conductive unit electrically coupled to the electrode and extending over a surface of the resin convexity, the conductive unit continuously covering: the opening formed in the protective layer; and the resin convexity; hot pressing the semiconductor device, substrate and bonding material within a temperature range including a glass transition temperature of the resin and a glass transition temperature of the bonding material, the glass transition temperature of the resin and the bonding material being about 220° C. to mount the semiconductor device onto the substrate at a temperature at least equal to a temperature at which an elastic modulus of the resin starts to decrease, the conductive unit being formed to cover the opening formed in the protective layer and spread over the resin convexity in one step.
