Abstract

Functional aqueous solution supply apparatus () has a replenishment water production unit () that is supplied with ultrapure water (W) from a pipe conduit () and produces functional aqueous solution as washing water (W), a storage tank () that is supplied/replenished with the produced washing water (W) via a pipe (), and a circulation pipe conduit () that supplies the washing water (W) from the storage tank () to single-wafer type washers (A,B,C, andD) and returns unused washing water (W) to the storage tank (). The circulation pipe conduit () is branched into supply pipes (A,B,C, andD) and is further connected to return pipes (A,B,C, andD) that communicate into the circulation pipe conduit () from the washers (A,B, . . . ), respectively. The operation plan of the washers (A,B, . . . ) is preliminarily transmitted to a control means (), and this control means () can control the replenishment water production unit (). Such a functional aqueous solution supply apparatus can supply the functional aqueous solution as the washing water to use points such as washing apparatuses for electronic components/electronic members, etc.
