Patent ID: 7176557

Claim:
A semiconductor device comprising: a sealing body formed of an insulating resin, the sealing body having an upper surface, a lower surface opposite to the upper surface, and side faces which connect the upper and lower surfaces with each other; an electrically conductive tab sealed within the sealing body; tab suspending leads contiguous to the tab and partially exposed to the lower surface and the side faces of the sealing body; a semiconductor chip fixed to a lower surface of the tab; a plurality of electrically conductive leads, the electrically conductive leads each having an inner end portion positioned within the sealing body and an outer end portion exposed to the lower surface and a side face of the sealing body; a projecting portion projecting from a side face of each of the tab suspending leads and positioned within the sealing body; and electrically conductive wires positioned within the sealing body and connecting electrodes formed over a lower surface of the semiconductor chip with the leads and the projecting portion.
