A semiconductor package includes a semiconductor chip formed with a non-volatile semiconductor memory, a resin encapsulation that encapsulates the semiconductor chip, electrodes in a lattice (solder balls) formed and arrayed in a lattice on a bottom surface of the resin encapsulation. The solder balls include a signal electrode formed within the central region of the array and a dummy electrode formed outside the signal electrode.

Storage medium and semiconductor package

A semiconductor device includes a lead frame having an element support and a lead portion. The lead frame has an area from the element support to inner leads of the lead portion, which is formed flat. First and second semiconductor elements are stacked in order on a lower surface of the lead frame. Electrode pads of the first semiconductor element are connected to the inner leads via first metal wires. Ends of the first metal wires, which are connected to the first semiconductor element, are embedded in the second adhesive layer of the second semiconductor element.

Semiconductor device

A semiconductor device includes a wring board having a first surface with external connection terminals and a second surface with internal connection terminals. On the second surface of the wiring board, a semiconductor chip having electrode pads is mounted. The electrode pads of the semiconductor chip and the internal connection terminals of the wiring board are electrically connected via connecting members. The external connection terminals are arranged along two opposite outer sides of the wiring board and each have a rectangular shape elongated in a direction toward the outer side.

A USB terminal having a conductor layer to be an input/output terminal of a USB connector is formed on a first principle surface of a circuit board. A memory element is mounted on a second principle surface at an opposite side of a terminal forming surface of the circuit board, and the memory element is sealed with a sealing resin. A semiconductor memory device as a USB memory main body is constituted by them. A USB memory is constituted by housing the USB memory main body inside of a USB connector case.

Semiconductor memory device and USB memory device using the same

A lead frame has a plurality of first inner leads having distal end portions and parallel to each other, and a plurality of second inner leads having distal end portions opposing the distal end portions of the first inner leads, longer than the first inner leads, and parallel to each other. The semiconductor chip has a plurality of bonding pads arranged along one side of an element formation surface, and is mounted on the surfaces of the plurality of second inner leads using an insulating adhesive. The plurality of bonding wires include first bonding wires which electrically connect the distal end portions of the plurality of first inner leads to some of the plurality of bonding pads, and a plurality of second bonding wires which electrically connect the distal end portions of the plurality of second inner leads to the rest of the plurality of bonding pads.
