Abstract
A lead frame includes a plurality of leads electrically connected to a semiconductor chip and a lead lock including a base layer disposed over the plurality of the leads and formed of a material having a coefficient of thermal expansion similar to that of inner leads. An adhesive layer is disposed between the base layer and the plurality of leads to fix the plurality of leads and adhere the base layer to the leads. At least one line electrically connects the semiconductor chip to the base layer of the lead lock. Since regions for bus bars are replaced by the lead lock and are removed, the lead frame can be miniaturized and has superior thermal stability and dimension stability.
