Abstract:
1. A method of manufacturing a semiconductor device, comprising the steps of: fixing an upper stage side semiconductor chip on a front surface of an inner lead part of a first lead frame and a lower stage side semiconductor chip on a rear surface of an inner lead part of a second lead frame; overlapping at least a part of a frame body part of the first lead frame and a part of a frame body part of the second lead frame; sealing with a mold resin the upper stage side semiconductor chip, the lower stage side semiconductor chip, the inner lead part of the first lead frame, and the inner lead part of the second lead frame; and separating the semiconductor device by removing the frame body part of the first lead frame and the frame body part of the second lead frame, such that the first lead frame and the second lead frame are electrically isolated from each other.
