Substrate processing apparatus, recording medium, and method of processing substrates

1. A substrate processing apparatus comprising:

a robot arm for conveying a substrate;

a conveyance chamber containing the robot arm, the conveyance chamber including a side having a surface, a rotatable first wall having an end rotatably attached to the side of the conveyance chamber at a first fixed location on the conveyance chamber and movable between a first position and a second position while attached to the conveyance chamber, and a rotatable second wall rotatably attached to the conveyance chamber at a second fixed location, the second wall movable with respect to the first wall and to the conveyance chamber; and

an adjacent processing chamber adjacent to the conveyance chamber, the adjacent processing chamber processing a substrate therein,

wherein the conveyance chamber is constructed so as to have a first shape for providing a predetermined space between the conveyance chamber and the adjacent processing chamber when the first wall is in the first position, the predetermined space including a distance between the first wall and the adjacent processing chamber, and a second shape for increasing the internal space of the conveyance chamber by making the distance between the first wall and the adjacent processing chamber smaller than when the first shape is formed when the first wall is in the second position, and

wherein the first wall and the second wall overlap when the first wall is in the first position and the first wall and the second wall intersect at a non-zero angle when the first wall is in the second position.

2. The substrate processing apparatus according to claim 1 , wherein the first wall and the second wall form a double door;

the first shape is realized by setting the double door in an overlapping state; and

the second shape is realized by bringing end portions of the double door into contact with each other.

3. The substrate processing apparatus according to claim 1 , further comprising:

a load lock chamber attached to the side surface of the conveyance chamber; and

a load port attached to a second side surface of the conveyance chamber,

wherein the load lock chamber is connected between the conveyance chamber and the adjacent processing chamber, and

wherein the conveyance chamber is positioned between the load lock chamber and the load port.

4. The substrate processing apparatus according to claim 1 , wherein the difference between the first shape and the second shape is produced at a height at which the robot arm operates.

5. The substrate processing apparatus according to claim 1 , wherein the difference between the first shape and the second shape is produced by the portion of the conveyance chamber that opposes the adjacent processing chamber when in the first shape.

6. The substrate processing apparatus according to claim 1 , further comprising:

a plurality of movable parts, including at least the first wall, that can project toward the adjacent processing chamber;

a sensor that detects the position of the plurality of movable parts;

a recording medium storing relationship data which associates the pattern of the internal space of the conveyance chamber with the operating range of the robot arm; and

a transfer conveyance module controller (TMC) that receives output of the sensor and determines the pattern, the TMC identifies the operating range of the robot arm corresponding to the determined pattern based on the relationship data stored in a recording medium.

7. The substrate processing apparatus of claim 1 , including a vacuum chamber, wherein the conveyance chamber is connected to the vacuum chamber and the adjacent processing chamber is connected to the vacuum chamber.

8. The substrate processing apparatus of claim 7 , including a load lock chamber connected to the conveyance chamber and the vacuum chamber.

9. The substrate processing apparatus of claim 8 , including a plurality of processing chambers arrayed around a periphery of the vacuum chamber.
