Abstract:
A substrate processing apparatus for performing predetermined processing on a group of substrates arranged in parallel at a first pitch, said substrate processing apparatus comprising:a) cassette moving means (231) for sequentially moving a plurality of cassettes (C) to a plurality of transfer positions which are shifted by said first pitch from each other, each of said cassettes being capable of receiving a predetermined number of substrates (W) arranged at a second pitch which is an integral multiple of said first pitch;b) transfer means (23) for holding said predetermined number of substrates in each of said plurality of transfer positions to take out said predetermined number of substrates from said plurality of cassettes;c) transport means (3) for receiving sequentially a plurality of times said predetermined number of substrates in association with said plurality of transfer positions from said transfer means to hold substrates having been received in said plurality of cassettes as said group of substrates to transport said group of substrates while holding said group of substrates; andd) processing means (4U) for performing said predetermined processing upon said group of substrates transported by said transport means.
