ABSTRACT:
A method of bonding wire between at least one pair of bond locations in a semiconductor device and the bonder. A conveyor is provided having a conveying surface for conveying in a predetermined direction a partially fabricated semiconductor device having first and second bonding locations. A first capillary is provided for forming a stitch bond to the first bonding location, the first capillary being disposed at an angle of about 45 degrees with respect to the predetermined direction and a line normal thereto and substantially parallel to the plane of the conveying surface. A stitch bond is formed on the first bonding location with the first capillary. The first capillary is at an angle of substantially 45 degrees with respect to a line normal to the plane of the conveying surface. A second capillary is provided for forming a stitch bond to the second bonding location, the second capillary being disposed at an angle of about 45 degrees with respect to the predetermined direction and a line normal to the predetermined direction and substantially parallel to the plane of the conveying surface and a stitch bond is formed on the second bonding location with the second capillary. The second capillary is at an angle of substantially 45 degrees with respect to a line normal to the plane of the conveying surface. The first and second capillaries are disposed at an angle of about 90 degrees with respect to each other with respect to each other in a direction normal to said plane.
