Abstract

A lead frame for use in a resin-sealed type semiconductor device, comprising an outer frame, a plurality of leads supported by the outer frame, arranged side by side and each composed of an inner lead and an outer lead, a die pad arranged inside the outer frame and located so that the tips of the inner leads are close to the die pad and oppose the die pad, and a resin flow-control body. The resin flow-control body has been formed by extending a portion of the outer frame toward the die pad through a space formed in the outer frame. The body is designed to be placed in a cavity of a mold having a gate communicating with the cavity, with the space located between the gate and the cavity, in order to form a resin sealing body.
