Abstract:
PURPOSE: A substrate processing apparatus, a substrate processing method, a recording media for a program implementing the method are provided to maintain the accuracy of the flow rate when processing liquid is supplied into processing units and integrates components for a flow rate controlling unit. CONSTITUTION: A processing liquid supplying part(70) supplies processing liquid to a supplying flow path(68a). A flow rate controlling unit(131) controls the flow rate of the supplying flow path. The flow rate controlling unit includes a flow rate measuring part(132), a flow rate controlling valves(133), a flow rate setting value and flow rate controlling part(134). A converting unit implements a converting operation between a first flow path(68c) and a second flow path(68d).
Abstract:
An apparatus for treating liquid is provided to prevent a mist of treatment liquid from scattering by using a rotating cup to rotate with a substrate. An apparatus for treating liquid includes a substrate holding unit(1), a rotating cup(3), a rotating device, a liquid feed device, an exhausting unit(8), and a guiding member. The substrate holding unit(1) holds horizontally a substrate and rotates with the substrate. The rotating cup(3) encloses the substrate and rotates with the substrate. The rotating device rotates the rotating cup(3) and the substrate holding unit(1) entirely. The liquid feed device supplies treatment liquid to a surface of the substrate. The exhausting unit(8) discharges gas and liquid from the rotating cub(3) to the outside. The guiding member is mounted outside the substrate. The guiding member rotates the substrate holding unit(1) and the rotating cup(3) together. The guiding member guides the treatment liquid to the exhausting unit(8).
Abstract:
A liquid treatment device is provided to suppress the bounding of mists in a processing liquid by using a rotating cup to rotate together with a substrate. A liquid treatment device includes a substrate holding portion(1), a rotating cup(3), a rotating tool, a liquid supply tool, and an exhaust and drain portion(6). The substrate holding portion(1) holds a substrate in a horizontal direction and is rotated according to a rotation of the substrate. The rotating cup(3) encloses the substrate and is rotated according to a rotation of the substrate. The rotating tool integrally rotates the rotating cup(3) and the substrate holding portion(1). The exhaust and drain portion(6) performs an exhaust and a drain of the rotating cup. The exhaust and drain portion(6) includes a drain cup for receiving a processing solution from the substrate and an exhaust cup for receiving and exhausting gas components.
Abstract:
방전식 오존 발생기에 의해 생성된 O 3 가스에 수증기가 혼합된다. 혼합 유체는 냉각 수단에 의해 냉각되며, 이것에 의해 O 3 가스에 함유되어 있던 금속 및 질소 산화물 등의 불순물이 응축수 속에 융해된다. 계속해서, 기액 분리기에 의해 O 3 가스가 응축수로부터 분리된다. O 3 가스에 수증기가 재차 혼합된다. 혼합 유체는 금속 흡착재로서, 다수의 실리콘 칩을 수용한 용기로 이루어지는 금속 칩을 통과함으로써, 잔존 금속이 제거된다.
Abstract:
Water vapor is mixed into an O3 gas generated by a discharge ozone generator. The mixed fluid is cooled by a cooling means, whereby impurities such as metals and nitrogen oxides contained in the O3 gas are dissolved into condensed water. Following that, the O3 gas is separated from the condensed water using a gas-liquid separator. Then, water vapor is mixed into the O 3 gas again. The resulting mixed fluid is passed through a metal trap composed of a container holding many silicon chips as a metal adsorbing material, whereby remaining metals are removed.
