Patent ID: 7414320

Claim:
A semiconductor device comprising: a first semiconductor element having a first surface of a quadrangle shape and a second surface of a quadrangle shape; and a second semiconductor element having a first surface of a quadrangle shape and a second surface of a quadrangle shape, the first semiconductor element placed above the first surface of the second semiconductor element so that the second surface of the first semiconductor element faces the first surface of the second semiconductor element, wherein a size of the first and second surfaces of the first semiconductor element are smaller than a size of each of the first and second surfaces of the second semiconductor element, and wherein a size of the first semiconductor element is smaller than a circuit element area of the second semiconductor element, and wherein the first semiconductor element is placed against one side of the second semiconductor element, so that an edge of the second surface of the first semiconductor element is not placed above a predetermined circuit block in the circuit element area of the second semiconductor element.
