Abstract:
A substrate processing system comprising:a first processing apparatus for performing single substrate processing on each of substrates to be processed;a second processing apparatus for performing batch processing on plural substrates to be processed with the substrates held by a boat;an interface apparatus to which the substrates processed by said first processing apparatus are transported one by one, said interface apparatus causing the substrates to be held by the boat, transporting the boat holding plural substrates to said second processing apparatus, and after completion of the batch processing, retrieving the boat;a first transfer mechanism for loading/unloading the substrate into/from the boat in the interface apparatus; anda second transfer mechanism for transferring the boat in the interface apparatus to the second processing apparatus,said interface apparatus including:a stage,a rotary table rotatably arranged on said stage, for placing the boat thereon, andpositioning means for turning said rotary table in a direction of displacement of the boat to permit the boat to be placed on said rotary table when the boat is being placed on said rotary table with a shift position thereof displaced from a reference position in a rotatable direction of said rotary table by said second transfer mechanism, and after completion of placement of the boat, turning said rotary table in a direction opposite to the displacement direction to thereby position the boat at the reference position.
