Abstract: In the field of advanced packaging, including wafer thinning, wafer level packaging, 3D packaging, wafer backside processing, and wafer reconstruction for multi chip packaging, temporary bonding technology plays a crucial role. A thorough analysis is conducted on the warpage caused by heterogeneous hot press bonding using this technology, and solutions are proposed, including the optimization of substrates and temporary bonding adhesives, the optimization of spin coating processes, and the adjustment of bonding parameters, to meet the demand for low warpage temporary bonding processes in advanced packaging.

Key words: advanced packaging, temporary bonding, warpage, substrate selection, process solution
