Abstract
A semiconductor device for fingerprint sensors reduces a mounting area of the semiconductor device and improves a processing capacity of assembling and testing process. The semiconductor device has a functional surface that provides a predetermined function. A semiconductor element has a circuit formation surface on which a plurality of electrodes are formed and a back surface opposite to the circuit formation surface. A part of the circuit formation surface functions as the functional surface. Wiring is formed on the back surface of the semiconductor element. A plurality of connection parts extends between the circuit formation surface and the back surface of the semiconductor element so as to electrically connect the electrodes to the wiring. A plurality of external connection terminals are exposed outside the semiconductor device on a side of the back surface of the semiconductor element.
