摘要

BSR (back-side via revealing) of TSV wafers after temporary bonding is very critical process within 3D integration. Adhesive performances of the temporary bonding were inspected step by step within BSR process by IR inspection system. We found out the delamination happened after backside dielectric deposition at specific pattern. The delamination area and structure were inspected and reported in this paper.
