Abstract

We have developed a new 3-dimensional stacking technology using wafer-to-wafer stacked method and evaluated the connectivity between TSV and micro-bump. The prototype 3-layer stacking device has been tried using our technology and the functional yield reached more than 60%. Using 8-inch wafer. We propose one of the design methodologies for a 3D stacked device.
