Zusammenfassung:The present invention provides a semiconductor device, a method of manufacture therefor, and an integrated circuit including the same. In one advantageous embodiment the semiconductor device includes a doped layer located over a semiconductor substrate and an isolation trench located in the doped layer. The isolation trench may further include a bottom surface and a sidewall. Additionally, the semiconductor device may include a dopant barrier layer located on the sidewall and a doped region located in the bottom surface.
