Patent attributes
An apparatus for cleaning substrates includes a substrate support that is configured to support a plurality of substrates horizontally as spaced regularly one above the other, a rotating device for rotating the substrate support and a liquid supply system for dispensing cleaning liquid onto the substrates. The substrate support has a base plate and support rods extending upright on the base plate. The support rods include fixed rods and at least one movable rod. The movable rods is movable between an open position to provide a passage that allows the substrates to be placed between the support rods, and a closed position at which the substrates are held by and between the support rods. Once the substrates are supported in this way, the substrates are rotated. Then, the cleaning liquid, such as a chemical solution(s) followed by a rinsing liquid, is dispensed onto all of the substrates as the substrates are being rotated.
