Patent ID: 8012859

Claim:
A method for depositing a silicon-containing film on a substrate, comprising: disposing the substrate in a batch processing system configured for performing atomic layer deposition (ALD) of the silicon-containing film; exposing the substrate to a non-saturating amount of a first precursor containing silicon; evacuating or purging the first precursor from the batch processing system; exposing the substrate to a saturating amount of a second precursor containing silicon or a dopant, wherein only one of the first and second precursors contains a halogen, and a reaction of the first and second precursors on the substrate forms the silicon-containing film and a volatile hydrogen-halogen (HX) by-product; evacuating or purging the second precursor and the HX by-product from the batch processing system; and repeating the exposing and evacuation or purging steps until the silicon-containing film has a desired thickness.
