Abstract
A semiconductor device includes a wiring board having connection pads thereon and a semiconductor chip mounted on the wiring board. The wiring board and the semiconductor chip are covered with a sealing portion. Conductive members are extended upward from the connection pads and are exposed from the sealing portion. Rewiring lines are connected to the exposed conductive members. Land portions are arranged on the sealing portion and are electrically connected to the conductive members through the rewiring lines.
Claims13
A semiconductor device comprising:
- a wiring board including a plurality of connection pads;
- a semiconductor chip mounted over the wiring board and including a plurality of electrodes each connected to an associated one of the connection pads;
- an insulating layer covering the semiconductor chip and the connection pads of the wiring board, the insulating layer being defined by a first edge and a second edge opposite to the first edge;
- a land formed on the insulating layer at a location in which a distance between the first edge and the location is smaller than a distance between the second edge and the location, the land being spaced from the first edge and not overlapping the semiconductor chip;
- a wiring line formed on the insulating layer, the wiring line being elongated from the land toward the second edge and terminating to produce an end portion that does not overlap the semiconductor chip;
- and
- a conductive member penetrating the insulating layer to form an electrical path between the wiring line and one of the connection pads.
