  • Abstract
    To obtain a defect free and dislocation free during SiGe deposition is the key for improving hole carrier mobility for 40 nm technology node and beyond. This paper presents a methodology to eliminate SiGe dislocation. The key step is to introduce SF6 during Si trench surface treatment after Si trench main etch.
