Abstract:
1. A substrate processing apparatus, comprising: a processing unit that includes a processing space in which a substrate is arranged, sequentially supplies mutually different plural kinds of processing liquid to the processing space to perform a predetermined wet processing to the substrate with respect to each processing liquid, releases the processing liquid used in the wet processing from a releasing portion downwards of the processing space in a predetermined direction upon each execution of the wet processing; a liquid retrieval unit that includes plural liquid retrievers, is separated from the processing unit, and is disposed below the processing unit, the plural liquid retrievers retrieving the plural kinds of processing liquid sequentially released from the releasing portion at each retrieval position predetermined with respect to each kind of the processing liquid; and a selective positioning unit that relatively moves the processing unit and the liquid retrieval unit to selectively position each of the liquid retrievers at each retrieval position corresponding to the kind of the processing liquid released from the releasing portion; wherein the liquid retrieval unit is moved in a horizontal direction by the selective positioning unit to the retrieval position corresponding to the kind of the processing liquid released from the releasing portion.
