Abstract:
A lead frame used for a resin-sealed semiconductor device, comprising:a die-mount portion on which a semiconductor chip rests; anda plurality of adjacent leads electrically connectable to the semi-conductor chip arranged along a common side of the lead frame,wherein:the plurality of leads include at least one adjusting lead not electrically connected to the semi-conductor chip, wherein the adjusting lead is used to adjust the pitch of the plurality of leads, andthe adjusting lead has a length that is less than the others of the plurality of leads such that a tip of the adjusting lead projects into an outer peripheral surface of a resin-seal body to prevent resin flash during a formation of the semiconductor device a distance which allows the adjusting lead to be removed after the resin-seal body is formed over a portion of the lead frame.
