Abstract:
A semiconductor device comprising:a first chip including a first semiconductor substrate having a first major surface on which a first integrated circuit is formed and a second major surface; and a second chip including a second semiconductor substrate having a third major surface on which a second integrated circuit is formed and a fourth major surface; wherein said first chip is flip-chip connected onto a base substrate, the fourth major surface of the second semiconductor substrate being mounted on the second major surface of the first semiconductor substrate, and said first and second chips being sealed with a first sealing resin; wherein said first chip comprising, ball pads; connecting members formed on the ball pads and connected to the base substrate; wirings which connect between the first integrated circuit and the ball pads; and a second sealing resin which seals the first major surface of the first semiconductor substrates, the wirings, and surfaces of the ball pads, except for the connecting members and contact portions between the ball pads and the connecting members.
