Semiconductor device

A semiconductor device comprising,

• at least two or more groups of external connection terminals to which a substrate that drives a semiconductor chip by inputting a signal from an external apparatus to the semiconductor chip is electrically connected, the at least two or more groups of external connection terminals being formed in a region outside an active region of the semiconductor chip, wherein
• among the at least two or more groups of external connection terminals, at least one group of terminals constitutes a first group of terminals on which a substrate for inspection connected to an external inspection apparatus and used to inspect the semiconductor chip is mounted, and another group of terminals different from the first group of terminals constitutes a second group of terminals on which a substrate for mounting used when the semiconductor device is mounted on an apparatus to be actually used, and
• the first group of terminals doubles as the second group of terminals, and the substrate for inspection doubles as the substrate for mounting, and the substrate for inspection doubling as the substrate for mounting is electrically connected to the first group of terminals.
