Abstract :
In this study, 3D IC integrations with a semi-embedded TSV interposer with stress relief gap under thermal operating and environmental conditions are investigated. Emphasis is placed on the determination of the TSV interposer warpage and the nonlinear stress and creep strain in the Al/Cu-low-k pads and micro solder joints.
