Patent ID: 7339261

Claim:
A method of manufacturing a semiconductor device, comprising the steps of: forming a lead frame, the lead frame comprising a plurality of leads, a tab for fixing a semiconductor chip, a plurality of tab suspending leads contiguous to the tab and each having a projecting portion projecting from a side face thereof, and a frame portion for connecting the leads and the tab suspending leads with one another, the leads, the tab, the tab suspending leads and the frame portion each having a first surface and a second surface opposite to the first surface, the leads and the projecting portions having wire connecting surfaces at least partially on the second surface, the wire connecting surfaces being positioned closer to the first surface side than the other portion; fixing a semiconductor element to the second surface of the tab; electrically connecting electrodes of the semiconductor element with the wire connecting surfaces of the leads and of the projecting portions on the second surface side through electrically conductive wires; sealing the semiconductor element, the wires, the leads, the tab suspending leads and the projecting portions of the tab suspending leads with an insulating resin so that the second surfaces of the leads and the tab suspending leads are exposed from the insulating resin, to form a sealing body; and cutting off the leads and the tab suspending leads from the frame portion.
