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.

Claim (Index 18):
A semiconductor device, comprising:\n a substrate; one or more shallow trench isolation regions defining an active region on the substrate, each of the one or more shallow trench isolation regions comprising a dielectric material; an undoped monocrystalline feature disposed on the substrate in the active region; and a first epitaxial silicon layer comprising:\n a horizontal portion located on the substrate, the horizontal portion having a first end proximate to one of the one or more shallow trench isolation regions and a second end adjacent to the undoped monocrystalline feature, wherein the first end has a first arsenic concentration and a first carbon concentration at a distance from the substrate; and \n a vertical portion normal to the horizontal portion and adjacent to the undoped monocrystalline feature, wherein the vertical portion has a third end adjacent to the second end of the horizontal portion and a fourth end distal to the third end, the fourth end having a second arsenic concentration and a second carbon concentration at a distance from the horizontal portion, wherein the first arsenic concentration and the second arsenic concentration have a variation of less than about 10%, and wherein the first carbon concentration and the second carbon concentration have a variation of less than about 10%.
