Patent ID: 7968993

Claim:
A stacked semiconductor device, comprising: a circuit substrate having an element mounting portion and connection portions; a first semiconductor element, mounted on the element mounting portion of the circuit substrate, having a first element main body, first electrode pads disposed at a surface of the first element main body, and a first insulating protective film covering the surface while exposing the first electrode pads; a second semiconductor element, stacked on the first semiconductor element, having a second element main body, second electrode pads disposed at a surface of the second element main body, and a second insulating protective film covering the surface while exposing the second electrode pads; first metal wires electrically connecting the connection portions and the first electrode pads; second metal wires electrically connecting the connection portions and the second electrode pads, the second metal wires being wired so that a part thereof is in contact with the first insulating protective film; and a resin-sealing portion sealing the first and second semiconductor elements together with the first and second metal wires.
