摘要:
A method for forming an opening within a semiconductor material comprises forming a neck portion, a rounded portion below the neck portion and, in some embodiments, a protruding portion below the rounded portion. This opening may be filled with a conductor, a dielectric, or both. Embodiments to form a transistor gate, shallow trench isolation, and an isolation material separating a transistor source and drain are disclosed. Device structures formed by the method are also described.
