Patent ID: 8464736

Claim:
A liquid reclaim system, comprising: (a) a proximity head capable of generating a first fluid meniscus and a second fluid meniscus on a surface of a wafer, wherein the second fluid meniscus is configured to confine the first fluid meniscus to prevent evaporation of a hot liquid chemistry included in the first fluid meniscus into a gas, wherein another gas is applied to the second fluid meniscus to confine the first fluid meniscus and the second fluid meniscus to a footprint on the wafer surface, the proximity head including: (i) at least one first inlet configured to supply the hot liquid chemistry to the first fluid meniscus, and (ii) at least one second inlet configured to supply a cold liquid chemistry to the second fluid meniscus; (b) a first supply tank for providing the hot liquid chemistry to the at least one inlet; (c) a second supply tank for supplying the cold liquid chemistry to the at least one second inlet; and (d) a liquid pump for removing the hot liquid chemistry mixed with at least a portion of the cold liquid chemistry to each of the first and second supply tanks for recirculation back to the proximity head as the hot liquid chemistry and the cold liquid chemistry; (e) a vacuum tank for receiving cold liquid chemistry removed from cold/gas fluid outlets.
