Abstract

Methods are provided for fabricating integrated circuits. In accordance with one embodiment, the method includes forming a portion of a semiconductor substrate at least partially bounded by a confinement isolation material. A liner dielectric is formed overlying the confinement isolation material and is treated to passivate a surface thereof. An epitaxial layer of semiconductor material is then grown overlying the portion of semiconductor substrate.
