Semiconductor package having multiple row of leads
Provided is a method of producing a semiconductor package including at least two rows of leads in which the leads of each row separately connecting a semiconductor chip to an external substrate. The method includes: forming a lead frame, the lead frame including a die pad and a plurality of leads arranged about the die pad; attaching an adhesive tape to a surface of the lead frame covering at least substantially the die pad and the plurality of leads; removing portions of the leads and the adhesive tape disposed in a dividing region and thereby separating at least some of the plurality of leads to form multiple rows of leads; and mounting a semiconductor chip on the die pad, electrically connecting the semiconductor chip with the lead frame, and molding the lead frame and the semiconductor chip to provide a semiconductor package. The adhesive tape attached at undesirable locations of the lead frame is preferably removed after provision of the semiconductor package.
