摘要：
A semiconductor integrated circuit includes a semiconductor chip having a plurality of pad electrodes fixed in a lead frame. Electrical leads connected to the chip include outer lead portions, external to the lead frame, and inner lead portions, internal to the lead frame and electrically connected to the semiconductor chip. At least one lead is a dummy lead, providing additional space in the lead frame. Due to the extra space, the inner lead portions may have various shapes, including large leads, or branched leads, for elimination power noise.
