Abstract
A lead frame used for a resin-sealed semiconductor device includes a die-mount portion on which a semiconductor chip rests; and a plurality of leads arranged along a common portion of the lead frame. The plurality of leads include at least one adjusting lead, and the adjusting lead has a length that is less than the others of the plurality of leads such that a tip of the adjusting lead is sufficiently proximate to an outer peripheral surface of a resin-seal body to prevent resin flash during a formation of the semiconductor device and to allow the adjusting lead to be removed after the resin-seal body is formed over a portion of the lead frame.
