For FUSI SOI CMOSFET, the impact of high stress contact etching stop layer (CESL) SiN layer on device performance and reliability were investigated. In this work, FUSI SOI n/pMOSFET driving capability and mobility can be enhanced with high tensile and compressive CESL layer in respectively; we found that high stress CESL layer will also induced more damages especially on 90 nnm device, resulting in FUSI SOI device degradation.
