Abstract

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