    摘要: A method and system for processing a substrate includes providing the substrate in a process chamber, the substrate having an oxide layer formed thereon, and exposing the substrate to an etching gas containing F2 gas at a first temperature to remove the oxide layer from the substrate. The substrate may subsequently be heated to a second temperature greater than the first temperature, and a film may then be formed on the substrate at the second temperature. In one embodiment, a Si film is epitaxially formed on a Si substrate.

    摘要: A method is provided for depositing a silicon-containing film on a substrate by a low pressure deposition process in a processing system. A silicon-containing film can be formed on a substrate by providing a substrate in a process chamber of a processing system, heating the substrate, and exposing a hexachlorodisilane (HCD) process gas to the substrate. The method can selectively deposit an epitaxial silicon-containing film on a silicon surface of a substrate or, alternately, non-selectively deposit a silicon-containing film on a substrate. A processing tool containing a processing system for forming a silicon-containing film on s substrate using a HCD process gas is provided.
