Patent ID: 8318548

Claim:
A method for manufacturing a semiconductor device, comprising the steps of: (a) providing a lead frame, the lead frame having a chip mounting portion and a plurality of leads arranged around the chip mounting portion, the chip mounting portion including a first chip mounting portion and a second chip mounting portion disposed side by side with the first chip mounting portion; (b) picking up a first semiconductor chip with a surface non-contact type collet and die-bonding the picked-up first semiconductor chip over the first chip mounting portion, wherein the first semiconductor chip is mounted over the first chip mounting portion through a paste material; (c) after the step (b), picking up a second semiconductor chip with a surface contact type collet and die-bonding the picked-up second semiconductor chip over the second chip mounting portion, the second semiconductor chip is mounted over the second chip mounting portion through a paste material; and (d) after the step (c), wire-bonding each of the first and second semiconductor chips, wherein after the step (c) and before the step (d) the paste material over the first chip mounting portion and the paste material over the second chip mounting portion are heat-cured at a time.
