Abstract:
A semiconductor device that is connected to a wiring substrate includes a semiconductor substrate, a circuit provided on the semiconductor substrate, a connection terminal, and a guard ring that is provided on a peripheral region. In the semiconductor device, the guard ring includes a plurality of wiring layers, and a wiring layer included in the guard ring, which is the farthest from the semiconductor substrate, corresponds to a wiring layer closer to the semiconductor substrate relative to a wiring layer of the connection terminal.
