摘要

Experimentally observed asymmetric breakdown characteristics of shallow trench isolation arc investigated by using TCAD. Both transient enhanced diffusion of boron and phosphorus and dcactivation of phosphorus piled up at the trench bottom arc the main causes of the asymmetry. Several techniques which reduce the asymmetry are proposed and their effects are compared by using TCAD.
