Abstract
Height control of a capillary is performed in a stitch bonding (2nd bond) in a wire bonding, so that a thickness of a stitch portion can be controlled, thereby ensuring a bonding strength at the stitch portion and achieving an improvement in a bonding reliability. Also, the stitch portion has a thick portion, and a wire and a part (α portion) of a bonding region of an inner lead is formed to a lower portion of the thick portion, thereby sufficiently ensuring a thickness of the stitch portion and a bonding region.
