Abstract

PURPOSE:To prevent the deformation of a lead frame due to thermal contraction of a tape, by a method wherein, in a lead frame of a system fixing an inner lead and a tab hanging lead, the central part of the tab hanging lead is made wide, and the end-portion of an insulating tape for lead fixing is fixed to the wide part. CONSTITUTION:A tab hanging lead 3 is provided with a wide width part 3A at the central part, in which a hole 3B is arranged to form a forked structure. The end-portions 5A of insulating tapes 5 for lead fixing are fixed on the respective parts of the forked structure. In the heating process such as a pellet fixing process, and a bonding process, the insulating tape 5 for lead fixing generates thermal contraction. However, since the end-portion of the insulating tape 5 for lead fixing is fixed to the tab hanging lead 3, it is pulled from both sides and hard to be deformed. Therefore, the deformation of the inner lead 4 can be prevented.
