Abstract
Among the many 3D technology options that are being explored today, the 3D-stacked IC approach has become a mature and economically viable technology and provides the highest density for 3D interconnects to date. One approach for IC stacking pursued by imec is the integration of Through Silicon Vias with extreme wafer thinning and backside processing on full CMOS wafers. This has been successfully demonstrated for the first time in a 300mm production line, and the compatibility of thin wafer handling with backside processing has been evaluated.
