摘要:
A processing apparatus comprises a plurality of process unit groups each including a plurality of process units for subjecting an object to a series of processes, the process units being arranged vertically in multiple stages, an object transfer space being defined among the process unit groups, and a transfer mechanism for transferring the object, the transfer mechanism having a transfer member vertically movable in the object transfer space, the transfer member being capable of transferring the object to each of the process units. The processing apparatus further comprises a mechanism for forming a downward air flow in the object transfer space, a mechanism for controlling the quantity of the downward air flow, and a mechanism for controlling the pressure in the object transfer space. Thus, a variation in condition of the object transfer space is reduced.

An apparatus for subjecting a plurality of wafers to coating and heating treatments, including a coating section for subjecting the wafers to a coating treatment one by one, a heating section for subjecting wafers which have undergone the coating treatment to a heating treatment all together, and an interface section arranged between the coating section and the heating section. The wafers are heat-treated in the heat treatment section while the wafers are stacked at intervals in a vertical direction in a boat. The wafers which have undergone the coating treatment are loaded into the boat by a conveying member in the interface section. The conveying member and the boat are surrounded by a surrounding space formed by a casing at the interface section. A circulation line is combined with an air supply and exhaust system, for circulating air in the surrounding space. A dehumidifier is arranged on the circulation line for dehumidifying air in the circulation line to provide localized dehumidification of the surrounding space formed by the casing.

A substrate holder positioning method, capable of positioning a substrate holder without using any positioning jig, includes: measuring a first position of a substrate held on a substrate holder included in a substrate carrying mechanism; carrying the substrate held on the substrate holder to a substrate rotating unit for holding and rotating the substrate; turning the substrate held by the substrate rotating unit through a predetermined angle by the substrate rotating unit; transferring the substrate turned by the substrate rotating unit from the substrate rotating unit to the substrate holder; measuring a second position of the substrate transferred from the substrate rotating unit to the substrate holder; determining the position of the center of rotation of the substrate rotating unit on the basis of the first and the second position; and positioning the substrate holder on the basis of the position of the center of rotation.
摘要:
A substrate transfer apparatus, for transferring a substrate from a first module to a second module, includes a moving base having a Y-motion axis for moving the moving base in Y-direction, and a substrate holding member mounted to the moving base via X-motion axis so as to move relative to the moving base to be in an advanced position and a retracted position relative to the moving base. The X-motion axis operates when the Y-motion axis is operating, if the X-motion axis must be parallel to the Y-motion axis when transferring the substrate from the substrate holding member to the second module.

The substrate carrying device includes a carrying passage forming member forming a carrying passage along which a substrate is carried, exhaust grooves extending parallel to the carrying passage in the upper surface of the carrying passage forming member, a plurality of pairs each of right and left carrying gas flow grooves formed in the upper surface of the carrying passage forming member, inclined to a substrate carrying direction so as to approach the exhaust grooves from the right-hand side and the left-hand side of the exhaust grooves, respectively, and having inner ends joined to the exhaust grooves, respectively, and gas spouting pores formed near outer ends of the carrying gas flow grooves to spout a gas for causing the substrate to float and for creating substrate carrying gas flows flowing from the outer ends of the carrying gas flow grooves toward the inner ends of the carrying gas flow grooves.
摘要:
On top of respective areas divided by partition plates, that is, a cassette station, a processing station, and an interface section in a coating and developing processing system, gas supply sections for supplying an inert gas into the respective areas are provided. Exhaust pipes for exhausting atmospheres in the respective areas are provided at the bottom of the respective areas. The atmospheres in the respective areas are maintained in a clean condition by supplying the inert gas not containing impurities such as oxygen and fine particles from the respective gas supply sections into the respective areas and exhausting the atmospheres in the respective areas from the exhaust pipes.
摘要:
Thermal processing unit sections each with ten tiers and coating processing unit sections each with five tiers are disposed around a first main wafer transfer section and a second main wafer transfer section, and in the thermal processing unit section, the influence of the time required for substrate temperature regulation processing on a drop in throughput can be reduced greatly by transferring the wafer W while the temperature of the wafer W is being regulated by a temperature regulation and transfer device.
摘要:
Supporting members are provided at three places, for example, on a frame section of a pair of tweezers. Each supporting member has a tapered face as an inclined guide for allowing a rim portion of a substrate to slide down to be guided to a predetermined position. A vertical wall which is formed continuing from the tapered face and being nearly perpendicular to a supported face of a wafer is provided at an upper end of the tapered face. Even when the rim portion of the wafer rises along the tapered face with the movement of the tweezers, the rim portion stops by hitting against the vertical wall, thereby preventing the wafer from falling from the tweezers.
摘要:
A method of subjecting a plurality of wafers to coating and beating treatments where a first boat is placed on a stage arranged in an interface section. The first boat is capable of containing the wafers stacked at intervals in a vertical direction. The stage is capable of moving in a horizontal direction, and has a plurality of positions for respectively placing a plurality of boats. The wafers are conveyed from a supply section to a coating section, and are subjected to a coating treatment one by one. The wafers, which have undergone the coating treatment, are conveyed to the interface section. The wafers, which have undergone the coating treatment, are loaded into the first boat placed on the stage, in the interface section. The first boat containing the wafers, which have undergone the coating treatment, is located at a transfer position by moving the stage. The first boat, located at a transfer position by moving the stage. The first boat, located at the transfer position, is conveyed from the stage into a heating section, and the wafers, which have undergone the coating treatment, are subjected to a heating treatment simultaneously and all together.
