The beneficial role played by non-conductive film (NCF) under-fill (UF) compared with the conventional capillary under fill (CUF) is meticulously investigated for the reliability issues in high-density 3D-integration at die/wafer-level. The NCF with co-efficient of thermal expansion (CTE) value of 35 ppm/°C tremendously reduces the local deformation of 20 pm-thick three-dimensionally (3D)-stacked...
One of the most serious reliability issues, the local deformation produced in the stacked LSI die/wafer with respect to the die thickness and the sub-surface structures formed after several stress-relief methods are systematically and extensively studied. From the electron backscatter diffraction (EBSD) analysis, a more than one degree (>1°) of local misorientation is created in the stacked LSI...
