Abstract:
A capillary for bonding a wire to an electrode pad on a semiconductor element and to a post portion, the capillary comprising:(a) a capillary main body including an end, the capillary main body having an accommodating portion; (b) a movable portion accommodated in said accommodating portion, and being slidable to a position protruding from the end of the capillary main body, said movable portion including a passage for inserting the wire to pass therethrough; and (c) a resiliently deformable member accommodated in said accommodating portion, and resiliently deformed therein so as to urge said movable portion towards the end of the capillary main body, wherein, when the wire is bonded onto the electrode pad on the semiconductor element, the wire is compressively bonded by said movable portion, and when the wire is bonded onto the post portion for connection to the electrode pad, the metal wire is compressively bonded by the end of the capillary main body and said movable portion.
