Abstract
PURPOSE: To raise a work efficiency of a semiconductor manufacture with no dam portion by integrally connecting one of the lead pieces to another for a tab portion and a portion covered with a sealing member finally.
CONSTITUTION: A lead frame 1 having generally a strip configuration is provided with a plurality of frame members arranged to a longitudinal direction, a tab portion 12 positioned in the substantially central portion of the frame member, plurality of lead pieces 13 extending to a direction far from the circumference of the tab portion 12 and supported by the frame member 11, and a resin member 14 for connecting the tab 12 to the lead pieces 13 and also interconnecting one of the lead piecs to another.
