    摘要: A method includes forming a blocking layer over a substrate, and etching the blocking layer to form a trench in the blocking layer. A dielectric layer is formed, wherein the dielectric layer comprises a first portion over the blocking layer, and a second portion in the trench. After the step of forming the dielectric layer, an implantation is performed to implant an impurity into the substrate to form a deep well region. After the implantation, the dielectric layer and the blocking layer are removed.

    摘要: A system and method for isolating semiconductor devices is provided. An embodiment comprises an isolation region that is laterally removed from source/drain regions of semiconductor devices and has a dielectric material extending over the isolation implant between the source/drain regions. The isolation region may be formed by forming an opening through a layer over the substrate, depositing a dielectric material along the sidewalls of the opening, implanting ions into the substrate after the deposition, and filling the opening with another dielectric material.
