  • Publication number: 20090081810
    Abstract: A substrate processing apparatus has a fluid supply means 20 for supplying fluid to a substrate W and a fluid collection means 21 for collecting the fluid in the vicinity of the substrate W, the fluid supply means 20 having a fluid spurt section 20a, the fluid collection means 21 having a fluid suction section 21a opening in the vicinity of the fluid spurt section 20a. Since the fluid collection means 21 suctions and collects the fluid floating around the substrate W as a result of the liquid having been supplied from the fluid spurt section 20a to the substrate W, it is possible to prevent the substrate W from being contaminated after the substrate W being processed with the fluid supplied from the fluid supply means 20.

  • Patent number: 6106635
    Abstract: A washing method provides a liquid jet washing by jetting a liquid against a rotating thin-plate-shaped workpiece from a nozzle which shifts while being positioned opposite a front or back surface of the workpiece, thus removing dust adhering to the front or back surface and thereby washing the workpiece. The locus of the shifting nozzle is caused to pass in the vicinity of, but not over, the center of rotation of the workpiece. Electronic circuitry present at the central portion of workpiece is prevented from suffering electrostatic breakage caused by collision with washing liquid. At the same time, an appropriate quantity of washing liquid is made to collide with the entire surface of a workpiece, so that the workpiece can be washed satisfactorily.

  • Patent number: 5860181
    Abstract: A method of and an apparatus for cleaning workpiece is suitable for cleaning a substrate such as a semiconductor substrate, a glass substrate, or a liquid crystal panel to a high level of cleanliness. The method of cleaning a workpiece comprises the steps of holding a workpiece, scrubbing the workpiece with a cleaning member, and rubbing the cleaning member against a member having a rough surface to carry out a self-cleaning of the cleaning member. The cleaning member which is contaminated by having scrubbed the workpiece is rubbed against the rough surface, and the rough surface scrapes the contaminant off the cleaning member. Therefore, the contaminant can effectively be removed from the cleaning member, and hence the cleaning member has a high self-cleaning effect.
