    摘要: A semiconductor device which permits reduction in the number of pins and in size thereof is provided. The semiconductor device comprises 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, an outer end portion exposed to the lower surface and a side face of the sealing body, and a projecting portion projecting into the sealing body from a side face of each of the electrically conductive leads; 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 on a lower surface of the semiconductor chip with the projecting portions of the electrically conductive leads and the tab suspending leads.
