Abstract
A memory card includes a substrate and a resin-molded layer. The substrate includes contact pads that are on a second face thereof for communication with a card reader. Semiconductor chips are on a first face of the substrate and electrically connected to the contact pads through bonding wires and circuit wiring. The resin-molded layer is on the first face and covers the chips.
Claims12
A memory card comprising:
- a substrate having inside and outside faces, circuit wiring formed on the inside face, and contact pads formed on the outside face and electrically connected to the circuit wiring, wherein the outside face forms a first surface of the memory card;
- at least one semiconductor chip on the inside face and electrically connected to the circuit wiring;
- and
- a resin layer formed on the entire inside face and covering the semiconductor chip and the circuit wiring, wherein an external surface of the resin layer forms a second surface of the memory card,
- wherein the resin layer defines a plane extending continuously along one edge of the external surface thereof, and inclined with respect to the external surface thereof.
