Abstract
We propose a new evaluation method of plasma process induced Si substrate damage, which utilizes the voltage shift under constant-current injection (VSCCI) at metal-Si interface. This method is applied to the plasma damaged Si substrate and the obtained depth profile of the defects in the Si correlates well with the electrical metal/Si contact property.
