Patent ID: 8223500

Claim:
A memory card comprising: a circuit board including at least a board electrode on a top face of the circuit board and an external electrode on a bottom face of the circuit board; a first semiconductor chip flip-chip mounted on the top face of the circuit board, the first semiconductor chip including a first semiconductor electrode; a second semiconductor chip including a second semiconductor electrode on a top face of the second semiconductor chip; a third semiconductor chip flip-chip mounted in an area on the top face of the circuit board, the area being different from an area where the first semiconductor chip is mounted, the third semiconductor chip including a third semiconductor electrode; a wire for connecting the second semiconductor electrode and the board electrode; a cover for covering a circuit formation area, the circuit formation area including the first semiconductor chip, the second semiconductor chip, the third semiconductor chip, and the wire provided on the top face of the circuit board; a primary sealing resin for sealing the first semiconductor chip and the third semiconductor chip; a secondary sealing resin for sealing only the wire and an area near the wire; wherein a bottom face of the second semiconductor chip is smaller than a top face of the first semiconductor chip, and the bottom face of the second semiconductor chip and the top face of the first semiconductor chip face each other and are laminated and fixed.
