Patent ID: 7347352

Claim:
A method of forming a wire loop interconnect between a first bond site and a second bond site using a capillary of a wire bonding machine, the method comprising the steps of: (1) bonding a wire to the first bond site to form a bump on the first bond site; (2) forming a fold of wire continuous with the bump, step (2) including in order (2.1) raising the capillary above the bump formed on the first bond site a distance between 1.01 and 1.55 times the diameter of the wire, (2.2) then moving the capillary horizontally away from the second bond site a distance between 1.01 and 1.55 times the diameter of the wire, and (2.3) then moving the capillary back toward the bump on the first bond site; (3) bonding the wire on top of the bump after forming the fold; (4) continuously forming a wire loop between the top of the bump and the second bond site; and (5) bonding the wire at the second bond site to terminate the wire loop, whereby the wire loop has a loop height less than or equal to 2.5 mils.
