Lead frame, method of manufacturing the same, and method of manufacturing a semiconductor device using the same
摘要:
In a method of manufacturing a lead frame for use in a leadless package such as a quad flat non-leaded package (QFN), a base frame is first formed which includes a region for resin-molding a plurality of semiconductor elements to be mounted on one surface of the base frame, the region being partitioned into land shapes, and in which a die-pad portion and lead portions around the die-pad portion are defined severally for the individual semiconductor elements to be mounted in each of the partitioned regions for resin-molding. Next, an adhesive tape is attached to the other surface of the base frame, and subsequently a cut portion is provided at a portion corresponding to a region between two adjacent partitioned regions for resin-molding, of the adhesive tape.
