Appl. No.:

16/439923

Inventors:

- Fort Washington PA, US
Ray L. Cathcart - New York NY, US
Cuong Huynh - Radnor PA, US
Deepak Sood - New Britain PA, US
Paul W. Sucro - Hatfield PA, US
Joseph O. DeAngelo - Winters CA, US

International Classification:

H01L 23/00
B23K 20/00
H01L 21/66

Abstract:

A method of forming a wire loop in connection with a semiconductor package is provided. The method includes the steps of: (1) providing package data related to the semiconductor package to a wire bonding machine; (2) providing at least one looping control value related to a desired wire loop to the wire bonding machine, the at least one looping control value including at least a loop height value related to the desired wire loop; (3) deriving looping parameters, using an algorithm, for forming the desired wire loop; (4) forming a first wire loop on the wire bonding machine using the looping parameters derived in step (3); (5) measuring actual looping control values of the first wire loop formed in step (4) corresponding to the at least one looping control value; and (6) comparing the actual looping control values measured in step (5) to the at least one looping control value provided in step (2).
