Definitions
- the present invention relates to a substrate processing apparatus for handling substrates such as liquid crystal panels and semiconductor wafers, and more particularly to an inspection apparatus for measuring or inspecting the operation accuracy and state of a substrate transport robot used in the substrate processing apparatus. Things.
- Single wafer multi-chamber type semiconductor manufacturing equipment is equipped with a transfer chamber and a plurality of processing chambers arranged around it, and is configured to perform individual semiconductor manufacturing processing in a consistent atmosphere.
- a semiconductor wafer hereinafter, referred to as a “wafer”
- a wafer transfer robot provided in the transfer chamber.
- a conventional general wafer transfer robot includes an elongated flat blade that holds a wafer horizontally, and an arm assembly that includes a link machine that supports the blade and expands and contracts and rotates in a horizontal direction.
- a single-door lock chamber is connected to the transfer chamber so that the transfer chamber and the processing chamber can be loaded into or removed from the semiconductor manufacturing apparatus without opening to the atmosphere.
- a cassette for storing a plurality of wafers at regular intervals in a vertical direction is set.
- the wafer cassette is supported on a cassette stage in a positioning device called a cassette indexer, and is vertically moved up and down. This makes it possible to position a desired wafer in the wafer cassette with respect to the blade of the wafer transfer robot, and to store and remove wafers.
