Abstract:
A system for use in monitoring contamination of fluid received from a remote fluid source to rinse one or more crystal wafers, the system comprising:a portable framework including a chamber which encloses a workspace to isolate the workspace from an environment in which the system is located;a rinsing bath mounted within the chamber and configured to receive the one or more crystal wafers for rinsing, the rinsing bath having an input port which detachably connects to the remote fluid source to receive fluid for passage over the crystal wafers;a cassette configured to support the one or more crystal wafers in the rinsing bath;a sealable container configured to receive the one or more crystal wafers after the one or more crystal wafers are rinsed so that the wafers may be transported from the chamber;a transport structure mounted on the framework to accommodate transport of the system to and from the remote fluid source; anda wafer-quality measurement apparatus configured to test one or more characteristics of a rinsed crystal wafer for comparison with an optimal wafer, any difference in the one or more characteristics being indicative of contamination of the fluid received from the remote fluid source.
