A programmable substrate support including a first substrate support that mates with a second substrate support to enable automatic switching between different types of substrates. The first substrate support is configured to support a first type of substrate and to mount to a substrate positioning system to enable handling of substrates of the first type. The second substrate support is configured to support a second type of substrate, and is further configured to mate with the first substrate support to form a mated configuration. The mated configuration enables the substrate positioning system to handle substrates of the second type. In a semiconductor wafer processing embodiment, the first substrate support is an end effector capable of handling wafers of a first size, such as 200 millimeter (mm) wafers, and the second substrate support is another end effector capable of handling wafers of a second size, such as 300 mm wafers. Of course, any size and type of substrate is contemplated. The first and second end effectors include complementary couplers that enables the second end effector to mount on top of the first end effector in the mated configuration. The complementary couplers may further include locating features to enable repeatable alignment between the end effectors.

Programmable substrate support for a substrate positioning system

A modular, transportable housing for storing substrates, such as semi-conductor wafers and masks, and for maintaining such substrates in a substantially clean environment. Substrates are supported within the housing by a plurality of combs which maintain the substrates in spaced relationship relative to each other. Access to the interior of the housing is permitted by a pivotal door assembly. A docking unit permits interface of the housing with a clean environment. Control circuitry provided in the docking unit detects the presence of a housing and loads/unloads the housing as directed by a host computer through a communication link. A memory device is preferably mounted to the housing for storing history and other information about the substrates within the housing. The host computer directs the control circuitry to retrieve the substrate information from the memory and relay the information to the host computer. During or after processing of the substrates, the host computer updates the memory as desired. In this manner, the host computer controls and tracks one or more docking units and associated substrate housings.

Substrate housing and docking system

A stage assembly for a substrate processing system including a cassette support assembly for receiving and supporting a cassette and an actuation and support assembly for supporting and moving the cassette and cassette support assembly between a loading position and a processing position. The processing position provides convenient and efficient access by a central processing system, and the loading position preferably places each cassette closer to, and aligned with, a front panel of the processing system for convenient access by an operator. The actuator and support assembly preferably includes a frame assembly and a rotating plate pivotally mounted to the frame assembly, where the cassette support assembly is mounted to the rotating plate for pivoting relative to the frame assembly. An actuator assembly mounted to the frame assembly flits the cassette support assembly between the loading and processing positions. A shaft assembly pivotally mounts the cassette support assembly to the rotating plate. An adjustable linkage assembly is mounted between the frame assembly and the shaft assembly, so that the cassette support assembly is rotated or swiveled by an adjustable amount between the loading and processing positions.

Stage assembly for a substrate processing system

A nesting passenger vehicle designed to improve access to subways and commuter trains by virtue of its reduced parking area requirements. A short cabin and a V shaped frame permit the vehicle to nest or horizontally stack into other vehicles of the same shape in a manner that requires a small amount of parking space per vehicle. The present invention provides a significant parking density advantage compared to conventional, privately owned automobiles.
