Plasma process-induced latent damage on gate oxide-demonstrated by single-layer and multi-layer antenna structures

摘要

In this paper, by using both single-layer (SL) and multi-layer (ML) or stacked antenna structures, a simple experimental method is proposed to directly demonstrate the pure plasma process-induced latent damage on gate oxide without any impact of additional defects generated by normal constant current stress (CCS) revealing technique. The presented results show that this method is effective for study of the latent damage
