Patent ID: 7625779

Claim:
A method of manufacturing a semiconductor device, comprising the steps of: (a) preparing said semiconductor device, said semiconductor device including a semiconductor chip having a main surface, an inclined surface formed on a periphery of said main surface and inclined with respect to said main surface, a plurality of electrodes formed over said main surface, a protective film formed over said main surface, with openings over said electrodes, a plurality of rearrangement wirings formed over said protective film, and a plurality of protruding electrodes, the plurality of electrodes being arranged differently than the plurality of protruding electrodes, the rearrangement wirings connecting the electrodes to corresponding ones of the protruding electrodes, said protective film having a groove separating a periphery portion of said protective film from a portion of said protective film disposed inwardly from said groove, said inclined surface being exposed to outside the semiconductor device and being formed outwardly from said groove, and said groove being exposed to outside the semiconductor device; (b) arranging said semiconductor device in a concave portion of a socket in a state such that said main surface of said semiconductor chip is directed toward a bottom surface of said concave portion; and (c) subjecting said semiconductor device to electrical inspection in a state in which said semiconductor device is fitted in said concave portion of said socket.
