摘要:
An outer covering wall (26) and an inner covering wall (27), which are capable of surrounding a rotor (24), can be horizontally moved. A wafer carrier waiting portion (30) is disposed right below the rotor (24). A wafer holding member (41) included in a wafer lifter (40) moves into a wafer carrier (C) containing wafers (W) and mounted on a stage (31) (sliding table 32) included in the wafer carrier waiting portion (30), lifts up the wafers (W) and transfers the wafers (W) to the rotor (24). The outer covering wall (26) or the inner covering wall (27) surrounds the rotor (24) to define a processing chamber. The wafers (W) held on the rotor (24) are subjected to a cleaning process in the processing chamber.

摘要:
A liquid processing apparatus 1 comprises a casing 5, a substrate holding mechanism 20 that holds a wafer (substrate to be processed) W, a process-liquid supplying mechanism 30 that supplies a process liquid, a draining cup 12 that receives a process liquid, and a draining pipe 13 that discharges a process liquid outside. The process-liquid supplying mechanism 30 includes a first chemical-liquid supply mechanism that supplies a hydrofluoric process liquid, and a drying-liquid supplying mechanism that supplies an organic solvent for drying a wafer W. A control part 50 causes the first chemical-liquid supplying mechanism to supply a hydrofluoric process liquid, and then causes the drying-liquid supplying mechanism to supply an organic solvent. In addition, before the control part 50 causes the drying-liquid supplying mechanism to supply an organic solvent, the control part causes a cleaning mechanism 10 to remove an alkaline component in a casing 5.
摘要:
The present invention provides a substrate cleaning method capable of removing particles from the entire surface of a substrate to be processed at a high removing efficiency. In the substrate cleaning method according to the present invention, a substrate to be processed W is immersed in a cleaning liquid in a cleaning tank 12. Then, ultrasonic waves are generated in the cleaning liquid contained in the cleaning tank 12, so that the substrate to be processed W is subjected to an ultrasonic cleaning process. While the substrate to be processed is being cleaned, a dissolved gas concentration of a gas dissolved in the cleaning liquid contained in the cleaning tank is changed.
摘要:
Disclosed is a substrate processing apparatus in which a liquid state raw material is maintained at a high-temperature and high-pressure fluid state by a cooling mechanism at a first raw material receiving unit, a supplying valve of a raw material supplying path is opened to provide the high-temperature and high-pressure fluid to a processing chamber where a target substrate is disposed, and the target substrate is dried by the high-temperature and high-pressure fluid. A second raw material receiving unit is cooled down below a condensation temperature of the raw material by a second cooling mechanism, the high-temperature and high-pressure fluid in the processing chamber is collected at the second raw material receiving unit by opening a collecting valve. The collected raw material is re-utilized as a raw material supplied from the first raw material receiving unit to the processing chamber.
摘要:
A liquid processing apparatus includes: a hollow holding plate configured to hold an object to be processed; a hollow outer rotational shaft fixedly connected to the holding plate; a rotary drive part configured to rotate the outer rotational shaft; and a lift pin plate disposed in a hollow space of the holding plate, and having a lift pin configured to support the object to be processed. Inside the lift pin plate, a cleaning-liquid supply part configured to supply a cleaning liquid is extended. Connected to the lift pin plate is a lifting member configured to locate the lift pin plate on an upper position and a lower position. When located on the lower position, the lift pin plate receives a force of the rotary drive part for rotating the outer rotational shaft so that the lift pin plate is rotated.

A liquid treating apparatus comprising a holding device (30) for holding wafers (W) in a substantially vertical attitude and a treating vessel (10) for accommodating the wafers held by the holding device. A treating liquid is supplied into the treating vessel by means of a treating liquid supply system. A rotational drive device (20) is provided for rotating the holding device (30) around a rotational axis passing approximately through the center of the wafers (W) in a state of non-contact with the treating vessel (10).
摘要:
The feature of the present invention is to enhance the throughput of manufacturing semiconductor wafers and/or liquid crystal substrates, by reducing the time required for performing a rinsing process. In this invention, the position of an object to be processed is controlled, such that a distance (L1) between the surface position (LV1) of a rinsing liquid upon the rinsing process and a top end position (LV2) of the object to be processed (wafers 2) becomes shorter than a distance (L2) between the surface position (LV3) of a chemical liquid upon a chemical liquid process and the top end position (LV4) of the object to be processed (wafers 2). Alternatively, the position of the object to be processed is controlled, such that the distance (L1) between the surface position (LV1) of the rinsing liquid upon the rinsing process and the top end position (LV2) of the object to be processed (wafers 2) becomes shorter than a distance (L3) between the bottom face position (LV5) of the rinsing liquid and a bottom end position (LV6) of the object to be processed (wafers 2).
