    Abstract: A device comprising Si:As source and drain extensions and Si:As or Si:P source and drain features formed using selective epitaxial growth and a method of forming the same is provided. The epitaxial layers used for the source and drain extensions and the source and drain features herein are deposited by simultaneous film formation and film etching, wherein the deposited material on the monocrystalline layer is etched at a slower rate than deposition material deposited on non-monocrystalline location of a substrate. As a result, an epitaxial layer is deposited on the monocrystalline surfaces, and a layer is not deposited on non-monocrystalline surfaces of the same base material, such as silicon.

    Abstract: Embodiments of the present disclosure generally relate to methods for forming a doped silicon epitaxial layer on semiconductor devices at increased pressure and reduced temperature. In one embodiment, the method includes heating a substrate disposed within a processing chamber to a temperature of about 550 degrees Celsius to about 800 degrees Celsius, introducing into the processing chamber a silicon source comprising trichlorosilane (TCS), a phosphorus source, and a gas comprising a halogen, and depositing a silicon containing epitaxial layer comprising phosphorus on the substrate, the silicon containing epitaxial layer having a phosphorus concentration of about 1×1021 atoms per cubic centimeter or greater, wherein the silicon containing epitaxial layer is deposited at a chamber pressure of about 150 Torr or greater.

    Abstract: Embodiments may include a method of semiconductor patterning including forming a first trench bordered by a first spacer material. The method may involve forming a second trench bordered by a second spacer material formed conformally around the first spacer material. The method may include filling the second trench with a semiconductor material.
