Cluster tool architecture for processing a substrate
A cluster tool for processing a substrate includes a cassette and a processing module including a first processing chamber that is configured to perform a chill process on a substrate, a second processing chamber that is configured to perform a bake process on the substrate, and an input chamber. The first processing chamber, the second processing chamber, and the input chamber are substantially adjacent to each other. The processing module also includes a robot that is configured to receive the substrate in the input chamber and transfer and position the substrate in the first processing chamber and second processing chamber. The robot includes a robot blade, an actuator, and a heat exchanging device. The heat exchanging device includes a chilled transfer arm assembly. The cluster tool also includes a 6-axis articulated robot configured to transfer the substrate between the cassette and the input chamber.
1. A cluster tool for processing substrates, comprising:
a cassette that is configured to contain two or more substrates;
a processing module comprising:
a first processing chamber that is configured to perform a chill process on a substrate supported above a surface of a chill plate in a first processing region;
a second processing chamber that is configured to perform a bake process on the substrate supported above a surface of a bake plate in a second processing region; and
an input chamber, wherein the first processing chamber, the second processing chamber, and the input chamber are substantially adjacent to each other;
a robot that is configured to receive the substrate in the input chamber and transfer and position the substrate in the first processing chamber and second processing chamber, wherein the robot comprises:
a robot blade;
an actuator that is configured to position the robot blade in the first and second processing chambers; and
a heat exchanging device that is in thermal communication with the robot blade and is configured to control the temperature of a substrate positioned thereon;
wherein the heat exchanging device comprises a chilled transfer arm assembly; and
a 6-axis articulated robot configured to transfer the substrate between the cassette and the input chamber.
