Abstract:
A semiconductor device comprising:a semiconductor substrate provided with a boundary scan test circuit having an I/O pad selecting function; and a plurality of pads provided on a principal plane of said semiconductor substrate and conducted to the boundary scan test circuit, said principal plane of said semiconductor substrate having a plurality of areas with each of which a test jig comes in contact, said plurality of areas including said plurality of pads, said I/O pad selecting function functioning to select at least one pad included in one area from said plurality of areas, said pads including: at least one set of driving pads for supplying a driving voltage of said semiconductor device; and at least one set of boundary scanning pads for performing a boundary scan test, and said at least one set of driving pads and said at least one set of boundary scanning pads being placed in such positions that said test jig can come in contact with one set of said at least one set of driving pads and one set of said at least one et of boundary scanning pads when said test jig comes in contact with any of said areas.
