Patent ID: 7847388

Claim:
A semiconductor device comprising: a semiconductor substrate having a main surface; first insulating film formed over the main surface; a plurality of electrodes formed over the first insulating film; a protective film formed over the electrodes and the first insulating film, the protective film having first openings over corresponding ones of the electrodes; a second insulating film formed over the protective film and having second openings over corresponding ones of the first openings; a plurality of rearrangement wirings formed over the second insulating film and electrically connected to corresponding ones of the electrodes through corresponding ones of the second openings; and a plurality of protruding electrodes formed over the rearrangement wirings and electrically connected to corresponding ones of the rearrangement wirings, wherein the protective film has a cut-out portion at a peripheral portion of the main surface, and wherein the cut-out portion of the protective film constitutes a groove and is arranged so as to separate the peripheral portion of the protective film from a portion of the protective film disposed inwardly from the groove.
