Abstract
The present invention is a transfer apparatus for a substrate, including a substrate housing container housing a substrate therein and having a transfer-in/out port for the substrate formed in a side surface thereof; a gas jet unit jetting a predetermined gas toward a rear surface of the substrate in the substrate housing container; and a control unit regulating a supply amount of the predetermined gas supplied from the gas jet unit to control the substrate in the substrate housing container to a predetermined height.
Claims14
A transfer apparatus for a substrate, which transfers the substrate between processing apparatuses, comprising:
- a substrate housing container housing a substrate therein and having a plurality of transfer-in/out ports for the substrate formed in a side surface thereof;
- a gas jet unit jetting a predetermined gas toward a rear surface of the substrate in said substrate housing container;
- and
- a control unit regulating a supply amount of the predetermined gas supplied from said gas jet unit to control the substrate in said substrate housing container to a predetermined height, wherein
- the plurality of said transfer-in/out ports are formed in a vertical direction in a side surface of said substrate housing container,
- said gas jet unit has a plurality of gas jet orifice jetting the predetermined gas obliquely upward from an inner side surface of said substrate housing container,
- the plurality of said gas jet orifices are provided in number and at positions matching the plurality of said transfer-in/out ports and are provided over a whole circumference of the inner side surface of said substrate housing container.
A transfer apparatus for a substrate, which transfers the substrate between processing apparatuses, comprising:
- a substrate housing container housing a substrate therein and having a transfer-in/out port for the substrate formed in a side surface thereof;
- a gas jet unit having a plurality of gas jet orifices vertically oriented and obliquely faced, the gas get unit jetting a predetermined gas toward a rear surface of the substrate in said substrate housing container;
- a control unit regulating a supply amount of the predetermined gas supplied from said gas jet unit to control the substrate in said substrate housing container to a predetermined height, and
- a position measurement unit measuring a height of the substrate in said substrate housing container,
- wherein said control unit regulates the supply amount of the predetermined gas to move the substrate to the predetermined height based on the height of the substrate measured by said position measurement unit.
