Semiconductor integrated circuit
Abstract:
There is offered a semiconductor integrated circuit provided with a function to electrically identify a location where a defect such as chipping of an LSI die or separation of resin is caused. Corresponding to each of the four corners of a semiconductor substrate, each of L-shaped first through fourth peripheral wirings having a first end and a second end is disposed on a periphery of the semiconductor substrate. The first end of each of the first through fourth peripheral wirings is connected with a power supply wiring. Each of first through fourth detection circuits detects breaking of corresponding each of the first through fourth peripheral wirings in response to a voltage at the second end of corresponding each of the first through fourth peripheral wirings, and outputs corresponding each of first through fourth detection signals to corresponding each of output pads.
