Abstract
A submicron photolysis polymer temporary bonding with ultra-fast laser de-bonding process of less than 20 s has been demonstrated where both photolysis polymer and polyimide are served as release layer and adhesive layer, respectively. In addition, the bonded structure provides high chemical resistance and mechanical strength for handling process. By measuring the electrical characteristics of devices before and after de-bond, it shows promising performance without degradation. Thus it can be a potential candidate for temporary bonding and de-bonding in 3D integration.
