SUBSTRATE CLEANING DEVICE, SUBSTRATE CLEANING SYSTEM, AND METHOD FOR THE SAME

摘要

PURPOSE: A substrate cleaning device, a substrate cleaning system, and a method for the same are provided to protect a substrate from a friction or a scratch and clean efficiently the substrate by maintaining an initial contact pressure. CONSTITUTION: A core material(68) for supplying pure water from a pure water supply path(60) is installed at a head(66) of a cleaning device(24). A plane portion(72) is formed at a lower portion of the core material(68). An outer face of the core material(68) is coated by a porous resin sheet(69). A rod(31) presses the cleaning device(24) to a substrate. An air bearing cylinder(30) is installed to transmit power to the rod(31). The pure water supply path(60) is formed inside the rod(31). The pure water supplied from the pure water supply path(60) is passed through the core material(68) and the porous resin sheet(69). A floating layer of the pure water is formed between the head(66) and the substrate.
