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 1×10 21  atoms per cubic centimeter or greater, wherein the silicon containing epitaxial layer is deposited at a chamber pressure of about 150 Torr or greater.

Claim (Index 3):
The method of  claim 1 , wherein the TCS and the HCl are flowed into the processing chamber at a flow ratio of about 12:1 to about 6:1.
