Abstract

A method for removing post-processing residues in a single wafer cleaning system is provided. The method initiates with providing a first heated fluid to a proximity head disposed over a substrate. Then, a meniscus of the first fluid is generated between a surface of the substrate and an opposing surface of the proximity head. The substrate is linearly moved under the proximity head. A single wafer cleaning system is also provided.
