摘要： Embodiments of methods and apparatus for cleaning contaminants from a substrate are disclosed herein. In some embodiments, a substrate cleaning apparatus includes: a substrate support to support a substrate along an edge of the substrate, wherein the substrate further includes a first side and an opposing second side having contaminants disposed on the second side; a showerhead disposed a first distance of about 1.5 mm to about 4.4 mm opposite the substrate support and facing the first side of the substrate; and one or more nozzles disposed a second distance of about 1 inch to about 2 inches beneath the substrate support to discharge a mixture of solid and gaseous carbon dioxide toward the contaminants on the second side of the substrate, and wherein the one or more nozzles have an angle of about 20 to about 40 degrees.
