Patent ID: 6853086

Claim:
A method of manufacture of a semiconductor device, comprising the steps of: providing an adhesive between a surface of a semiconductor chip having a plurality of electrodes on which said electrodes are provided and a surface of a substrate having a plurality of leads and an undivided film on which said leads and said undivided film are formed; positioning at least one of said plurality of electrodes to be opposed to at least one of said plurality of leads such that said undivided film is opposed to said semiconductor chip; and applying pressure in a direction such as to make a gap between said semiconductor chip and said substrate narrower such that said adhesive extends to be disposed on the whole of said undivided film; wherein said undivided film is formed with a lower adhesion to said adhesive than a base material of said substrate, and said undivided film is broader than each of said leads at their portions opposed to said electrodes, and said undivided film is formed to be electrically isolated from both said electrodes and said leads, wherein a region on which said adhesive is disposed includes a first region with low adhesion to said adhesive and a second region with high adhesion to said adhesive, an area of said first region≧an area of said second region.
