Abstract
A substrate processing apparatus includes a processing chamber that processes a substrate, and a substrate placing base enclosed in the processing chamber, and a substrate transporting member that allows the substrate to wait temporarily on the substrate placing base, and exhaust holes provided so as to surround the substrate placing base, and a retracting space that allows the substrate transporting member to move in between lines each connecting the exhaust hole and an upper end of the substrate placing base and the substrate placing base.
Claims6
A substrate processing apparatus comprising:
- a processing chamber that processes a substrate;
- a substrate placing base enclosed in the processing chamber;
- a substrate transporting member that allows the substrate to wait temporarily on the substrate placing base;
- a plurality of exhaust holes provided so as to surround the substrate placing base, and
- a retracting space in which the substrate transporting member moves, the retracting space at least partly surrounding the substrate placing base and being disposed in the processing chamber inside a boundary that connects the plurality of exhaust holes to an upper end of the substrate placing base.
A substrate processing apparatus comprising:
- a transporting chamber that transports a substrate;
- and
- a processing chamber that receives the substrate from the transporting chamber and processes the received substrate, wherein
- the transporting chamber includes a first substrate transporting member that transports the substrate from the transporting chamber to the processing chamber,
- the processing chamber includes:
- a first processing unit being positioned adjacent to the transporting chamber and having a first substrate placing base,
- a second processing unit being positioned adjacent to the first processing unit on the side different from the transporting chamber and having a second substrate placing base,
- a second substrate transporting member that transports the substrate between the first processing unit and the second processing unit,
- a plurality of exhaust holes provided that surround the second substrate placing base, and
- a retracting space in which the second substrate transporting member retracts, the retracting space at least partly surrounding the second substrate placing base and being disposed in the processing chamber inside a boundary that connects the plurality of exhaust holes to an upper end of the second substrate placing base.
A substrate processing method comprising the steps of:
- moving a substrate to above a first substrate placing base in a processing chamber by a first substrate transporting member provided in a transporting chamber;
- transferring the substrate from the first substrate transporting member to a first substrate supporting portion and a second substrate transporting member;
- moving the second substrate transporting member to a position above the second substrate placing base and waiting at the position above the second substrate placing base;
- placing the substrate on the second substrate placing base while moving the second substrate transporting member in a retracting space that at least partly surrounds the second substrate placing base and is disposed in the processing chamber inside a boundary that connects the plurality of exhaust holes to an upper end of the second substrate placing base;
- and
- exhausting gas from the plurality of exhaust holes while supplying the processing gas to the processing chamber and processing the substrate.
