Abstract
A lithography includes a storage tank that stores process chemical fluid, an anti-collision frame, and an integrated sensor assembly. The storage tank includes a dispensing port positioned at a lowest part of the storage tank in a gravity direction. The anti-collision frame is coupled to the storage tank. An integrated sensor assembly is disposed on at least one of the anti-collision frame and the storage tank to measure a variation in fluid quality in response to fluid quality measurement of fluid.
