  • Publication number: 20050183750
    Abstract: A substrate cleaning apparatus comprises an outer shell constructed such that the outer shell is selectively openable or hermetically closable to form a sealed space, an inner shell enclosed within the outer shell and having a holding member for holding a substrate, and a dispenser unit for feeding at least one of gas and liquid into the inner shell. Within the sealed space formed by the outer shell, a highly gas-tight space is formed by the inner shell to permit cleaning of the substrate within the highly gas-tight space. Also disclosed are a dispenser, a substrate holding mechanism and a substrate cleaning chamber, which are suitable for use with the substrate cleaning apparatus, and substrate cleaning processes making use of these dispenser, substrate holding mechanism and substrate cleaning chamber, respectively.

  • Patent number: 6866723
    Abstract: A wet treatment method useful in one of a chemical processing and a rinsing step performed upon fabrication of semiconductor devices. A substrate is treated with a desired liquid while revolving the substrate around an axis of rotation outside the substrate such that the liquid flowing on a surface of the substrate is maintained flowing under a centrifugal force greater than gravitation. The substrate is treated while supplying the liquid at a flow rate at least equal to a discharge rate of the liquid only in a direction conforming with that of the centrifugal force or with that of a flow of the liquid flowing on the surface of the substrate under the centrifugal force. The substrate surface is evenly treated with the liquid while avoiding flows of the liquid running against each other or a flow of the liquid stagnating on the surface of the substrate.

  • Publication number: 20020036006
    Abstract: A wet treatment method useful in at least one of a chemical processing step and a rinsing step performed upon fabrication of semiconductor devices is disclosed. According to this method, a substrate under treatment is treated with a desired liquid while causing the substrate to revolve around an axis of rotation outside the substrate itself instead of allowing the substrate to rotate about the axis of rotation such that the liquid flowing on a surface of the substrate is maintained flowing under a centrifugal force greater than gravitation. The substrate is treated while supplying a fresh liquid of the same kind as the desired liquid at a flow rate at least equal to a discharge rate of the desired liquid only in a direction conforming with that of the centrifugal force or with that of a flow of the liquid flowing on the surface of the substrate under the centrifugal force.
