Abstract:
1. A method of forming a semiconductor structure comprising: providing a substrate having silicon-containing portions in a chamber; and concurrently flowing a carrier gas, a silicon precursor gas, and a carbon precursor gas into said chamber, wherein said carrier gas is flowed at a flow rate less than 15 standard liters per minute, wherein Si:C containing regions are formed directly on said silicon-containing portions at a substantially pattern-independent deposition rate irrespective of structural patterns around said silicon-containing portions, and wherein said Si:C containing regions are single crystalline and contain carbon at an atomic concentration from about 0.01% to about 3.0 percent, said carbon is located in substitutional sites of a Si:C lattice in said Si:C containing regions, and wherein interstitial sites of said Si:C containing regions are substantially free of carbon.
