Patent ID: 8310068

Claim:
A tape carrier package (TCP) type semiconductor device connected to a plurality of substrate-side electrodes parallel to each other and each having a linear shape, the TCP type semiconductor device comprising: a base film; a semiconductor chip mounted on said base film; and a plurality of leads formed on said base film, each lead of the plurality of leads comprising a first end and a second end, the first end electrically connecting to said semiconductor chip and the second end electrically connecting to a corresponding one of said plurality of substrate-side electrodes, respectively, wherein each of said plurality of leads includes an external terminal section extending in a first direction and configured to come in contact with a corresponding one of said plurality of substrate-side electrodes, wherein a part of said external terminal section of each lead of the plurality of leads comprises a wide section that is formed wider than an other section of said external terminal section, and wherein a position of said wide section in said first direction is different between adjacent leads of said plurality of leads.
