Abstract
We designed and measured test element group wafers thinned to 10μm for 3D system in package. The n-well - p-Si diodes in 10 μm thick wafer showed increasing of the reverse saturation current in comparison to the currents in 20μm, 30 μm or 640 μm thick wafer. While the pMOSFETs and nMOSFETs in 10μm thick wafer showed no degradation of mobility, sub-threshold swing and threshold voltage. Defects might be induced by mechanical stress during wafer back grinding process near wafer back side, within a few micron-meters from the wafer back surface.
