  • Abstract
    We have studied the residual stress formation in the metal film of a Through Silicon Via (TSV) technology. The film is deposited by a CVD process in the TSV´s wall and a residual stress arises due to this process. Our goal was to develop a methodology to estimate the stress based on growth parameters. The calculation results exhibit a good agreement with experiments, although there is a tendency for stress underestimation.
