Abstract: A substrate cleaning apparatus may include a substrate support having a support surface to support a substrate to be cleaned, wherein the substrate support is rotatable about a central axis normal to the support surface; a first nozzle to provide a first cleaning gas to a region of the inner volume corresponding to the position of an edge of the substrate when the substrate is supported by the support surface of the substrate support; a first annular body disposed opposite and spaced apart from the support surface of the substrate support by a gap, the first annular body having a central opening defined by an inner wall shaped to provide a reducing size of the gap between the first annular body and the support surface in a radially outward direction; and a first gas inlet to provide a first gas to the central opening of the first annular body.
