  • Patent number: 7578886
    Abstract: A substrate processing apparatus and a substrate processing method is provided for performing a chemical liquid process, a cleaning process, a drying process, or the like while rotating a substrate such as a semiconductor wafer or a liquid crystal substrate. A substrate holding apparatus is provided for holding and rotating a substrate. The substrate processing apparatus for processing a substrate while supplying a fluid to the substrate includes a substrate holder for holding and rotating the substrate, and a holder suction unit for sucking the fluid from the substrate holder. The substrate holding apparatus includes a plurality of rollers which are brought into contact with an edge portion of a substrate so as to hold and rotate the substrate, and at least one moving mechanism for moving the rollers.

  • Publication number: 20090090397
    Abstract: The present invention provides a substrate processing apparatus and a substrate processing method suitable for use in an etching apparatus which etches a thin film formed on a peripheral portion of a substrate. The present invention also provides a substrate processing apparatus and a substrate processing method suitable for use in a cleaning apparatus which performs a cleaning process on a substrate which has been etched. The substrate processing apparatus for use in etching includes a substrate holder 11 for holding a substrate W substantially horizontally and rotating the substrate W, and a processing liquid supply unit 15 for supplying a processing liquid onto a peripheral portion of the substrate W which is being rotated in such a manner that the processing liquid is stationary with respect to the substrate W.

  • Publication number: 20080017220
    Abstract: The present invention relates to a cleaning apparatus which can reduce a potential difference between metals or alloys used to form interconnects on a substrate for thereby minimizing corrosion which may occur during and after a substrate cleaning process. The cleaning apparatus for cleaning a substrate having metal interconnects comprises a cleaning mechanism for cleaning the substrate, and a functional water supply mechanism for supplying functional water to the cleaning mechanism. The cleaning mechanism cleans a surface of the substrate with use of the functional water.

  • Publication number: 20040216841
    Abstract: A substrate processing apparatus processes a substrate such as a semiconductor wafer by supplying a processing liquid. The substrate processing apparatus includes a substrate holder (1) for holding and rotating a substrate (W), a lower surface processing unit (2) for processing a lower surface of the substrate (W) by supplying a processing liquid to the lower surface of the substrate (W), and an outer circumferential edge processing unit (3) for processing an outer circumferential edge of the substrate (W) by supplying the processing liquid to the outer circumferential edge of the substrate (W). The substrate processing apparatus further includes a gas supply unit (5) for supplying a gas to an upper surface of the substrate (W).
