Abstract
A method for removing one or more processing by-products found in deposition systems, such as in vacuum forelines of vapor deposition systems is provided. The method comprises performing a deposition process to deposit a layer on a substrate positioned in a deposition chamber. Hydrogen-containing by-products are produced in a vacuum foreline fluidly coupled with the deposition chamber during the depositing process. The method further comprises flowing an oxidizing agent gas into the vacuum foreline to react with at least a portion of the hydrogen-containing by-products in the foreline.
