SUBNANOMETER-LEVEL LIGHT-BASED SUBSTRATE CLEANING MECHANISM
Various embodiments comprise apparatuses and related methods for cleaning a substrate. In one embodiment, an apparatus includes a substrate holder to hold and rotate the substrate at various speeds. An optional inner shield and an optional outer shield, when in a closed position, surround the substrate holder during operation of the apparatus. Each of the inner shield and the outer shield can operate independently in at least one of rotational speed and direction from the other shield. At least one of a front-side laser and a back-side laser are arranged to clean one or both sides of the substrate and edges of the substrate substantially concurrently or independently by impinging a light onto at least one surface of the substrate. A gas flow, combined with a high rotational-speed of the shields and substrate, assists in removing effluents from the substrate. Additional apparatuses and methods of forming the apparatuses are disclosed.
