Abstrakt: The strained nitride capping layer (contact etch stop layer, CESL) is used as a stress booster that make transistor improvement. In this research, the n-MOSFET was simulated combining CESL tensile stressor. The stress in channel region for various part of CESL(CESL-top, CESL-lateral, CESL-bottom) were analysed and compared. The result of simulation explains how the CESL transmits the intrinsic stress to the channel. The relations between different CESL structures are discussed in this study.
