Abstract

A method for manufacturing a semiconductor device includes (i) a step of preparing a first semiconductor chip having a first electrode pad thereon and a second semiconductor chip having a second electrode pad thereon and larger in thickness than the first semiconductor chip, the second electrode pad being larger in size than the first electrode pad, (ii) a step of mounting the first semiconductor chip and the second semiconductor chip on the same planarized surface of a substrate having a uniform thickness, (iii) a step of bonding a ball formed by heating and melting a bonding wire to the second electrode pad, (iv) a step of first-bonding the bonding wire to the first electrode pad, and (v) a step of second-bonding the bonding wire to the ball.
