CHEMICAL DISPENSING SYSTEM

Abstract:

A chemical dispensing system is capable of simultaneously supplying a semiconductor processing chemical for production and testing through the use of independent chemical supply lines, which reduces production downtime of an associated semiconductor process, increases throughput and capability of the semiconductor process, and/or the like. Moreover, the capability to simultaneously supply the semiconductor processing chemical for production and testing allows for an increased quantity of semiconductor processing chemical batches to be tested with minimal impact to production, which increases quality control over the semiconductor processing chemical. In addition, the independent chemical supply lines may be used to supply the semiconductor processing chemical to production while independently filtering semiconductor processing chemical directly from a storage drum through a filtration loop.
