Abstract

In accordance with one or more aspects of the disclosed embodiment a semiconductor processing apparatus is provided. The semiconductor processing apparatus includes a frame forming a sealable chamber having a longitudinal axis and lateral sides astride the longitudinal axis, the sealable chamber being configured to hold a sealed environment therein, at least one transport module mounted to the sealable chamber and having a telescoping carriage being configured so that the telescoping carriage is linearly movable relative to another portion of the transport module where the telescoping carriage and the other portion define a telescoping motion along the longitudinal axis, and at least one transfer robot mounted to the carriage, each of the at least one transfer robot having at least one transfer arm configured for holding a substrate thereon.

First claim

1 . A semiconductor processing apparatus comprising:
a frame forming a sealable chamber having a longitudinal axis and lateral sides astride the longitudinal axis, the sealable chamber being configured to hold a sealed environment therein; at least one transport module mounted to the sealable chamber and having a telescoping carriage being configured so that the telescoping carriage is linearly movable relative to another portion of the transport module where the telescoping carriage and the other portion define a telescoping motion along the longitudinal axis; and at least one transfer robot mounted to the carriage, each of the at least one transfer robot having at least one transfer arm configured for holding a substrate thereon.

2 . The semiconductor processing apparatus of claim 1 , wherein a telescoping travel path of the telescoping carriage crosses an axis of entry/exit through a transport chamber opening through which a substrate holding station is communicably coupled to the transport chamber.

3 . The semiconductor processing apparatus of claim 1 , wherein the at least one transport module is removable from the sealable chamber as a unit.

4 . The semiconductor processing apparatus of claim 1 , wherein the at least one transfer robot is configured so that the at least one transfer arm is rotatable relative to the telescoping carriage.

5 . The semiconductor processing apparatus of claim 1 , wherein the sealed environment is a vacuum environment and the at least one transfer robot includes a sealed drive section disposed within the vacuum environment.

6 . The semiconductor processing apparatus of claim 1 , wherein the transport module includes a base member to which the telescoping carriage is movably mounted, the base member being fixedly and stationarily mounted relative to the frame.

7 . The semiconductor processing apparatus of claim 1 , wherein the at least one transfer robot and telescoping carriage are configured so that positioning of the telescoping carriage within the sealable chamber is effected substantially independent of positioning of the at least one transfer arm for picking and placing substrates.

8 . The semiconductor processing apparatus of claim 1 , the semiconductor processing apparatus further comprising kinematic locating features configured to engage the telescoping carriage for positioning the telescoping carriage within the sealable chamber.

9 . The semiconductor processing apparatus of claim 1 , the semiconductor processing apparatus further comprising a controller and one or more sensors connected to the controller, the one or more sensors being located and configured to sense the telescoping carriage within the sealable chamber and the controller being configured to determine a position of the telescoping carriage within the sealable chamber based on signals from the one or more sensors.

10 . The semiconductor processing apparatus of claim 1 , the semiconductor processing apparatus further comprising a controller and one or more sensors connected to the controller, the one or more sensors being located and configured to sense a substrate within the sealable chamber that is carried by the at least one transfer robot and the controller being configured to effect automatic wafer centering during transport of the substrate by the at least one transfer robot.

11 . The semiconductor processing apparatus of claim 1 , wherein the telescoping carriage spans a width that extends from adjacent one lateral side of the sealable chamber to another lateral side of the sealable chamber.

12 . The semiconductor processing apparatus of claim 1 , wherein the at least one transport module includes two telescoping carriages arranged laterally side by side within the sealable chamber.
