Abstract:
A method of stitch bonding wire to a bonding location in a semiconductor device which comprises the steps of:(a) providing a partially fabricated semiconductor device including a lead frame having lead fingers and a semiconductor chip having an exposed major surface with bond pads on said major surface disposed on said lead frame, a first axis parallel to said lead frame and said exposed major surface denoted herein as the x-axis, said partially fabricated semiconductor device having a first bonding location;(b) providing a first capillary for forming a stitch bond to said first bonding location, said first capillary being disposed at an angle of about 45 degrees with respect to said x-axis and a second axis parallel to said lead frame and said exposed major surface and normal to said x-axis denoted herein as the y-axis; and(c) forming a stitch bond on said first bonding location with said first capillary disposed at said angle of about 45 degrees with respect to each of said x and y axes.
