| Abstract: | Ultrasonic wire bonding is one of the most important technologies in chip interconnection of integrated circuits. Correct understanding on bonding mechanism and ultrasonic effect during ultrasonic bonding process is a major concern to get reliable bond and to optimize the process window. Ultrasonic wire bonding mechanisms were reviewed, and four mechanisms were summed up and discussed including heat based theory, dislocation theory, deformation theory and micro - slip theory. |
