Latest Patents

Dong Won Koo holds a patent for a method titled "Method for improved cleaning of substrate processing systems." This patent describes a multiple-stage microwave plasma cleaning technique designed to efficiently clean a substrate processing chamber. The first stage involves flowing a reactive gas from a gas source into the processing chamber, where microwaves ignite and maintain a plasma. The reactive radicals generated react with residues on the interior surfaces of the chamber. In the second stage, an inert gas is introduced alongside the reactive gas, allowing for further cleaning through plasma maintenance. The preferred reactive gas in this method is NF₃, although other fluorine-containing gases like carbon tetrafluoride (CF₄) or sulfur hexafluoride (SF₆) can also be utilized.
