Abstract: According to one embodiment, a semiconductor device includes: a first frame, a second frame spaced apart from the first frame in a first direction, and a first joint terminal provided above a second chip provided on the second frame. The first frame includes a first terminal portion extending toward the second frame. The first joint terminal includes a second terminal portion extending toward the first frame. The second terminal portion includes a plane portion, a first projecting portion and a second projecting portion each branching out from the plane portion. An end portion of the first projecting portion and an end portion of the second projecting portion are respectively joined on the first terminal portion. The first projecting portion is different in a length in a first direction from the second projecting portion.

Abstract: An electronic device module includes a wiring board having a first surface including first and second electrodes formed thereon and a second surface opposite to the first surface, a supporting member attached to the second surface of the wiring board, a first electronic unit mounted on the first surface of the wiring board and electrically connected to the first electrode, and a second electronic unit mounted on the first surface of the wiring board and electrically connected to the second electrode. The wiring board includes a wiring extending from the first electronic unit to a position closer to the second electronic unit, and a reinforcement layer disposed between the first and second electronic units and apart from the wiring in a thickness direction of the wiring board.
