Abstract
The semiconductor device includes a semiconductor element having an electrode formed on a surface thereof, and a metal wiring formed on the surface of the semiconductor element and electrically connected to the electrode. The metal wiring has an external electrode portion functioning as an external electrode. A thickness of the external electrode portion is greater than that of a non-electrode portion of the metal wiring, i.e., a portion of the metal wiring other than the external electrode portion.
