Abstract

A lead frame for reducing detrimental effects of burr formation includes a lead frame that has leads where a portion of a top surface is removed from a first lead and a portion of a bottom surface is removed from a second lead adjacent to the first lead to reduce spacing between leads while reducing the detrimental effects of burr formation, such as shorting and the like, caused during singulation of a semiconductor device manufactured with the lead frame.
