ABSTRACT:
Three embodiments of MicroCube Interconnection Hardware are disclosed: the MicroVac Vacuum Generator, the MicroControl Module, and the MicroSensor. Each embodiment is a combination of a MicroCube Precision Fitting and Various enhancements which provide precision control, regulation, or measurement of flows of gas or liquid in a semiconductor fabrication environment. The Microcube Precision Fitting is a substantially cubical unitary body that includes a central chamber and at least one external port. Each port comprises an annular counterbored step surrounded by a support wall which both enclose an aperture that extends into the central chamber. The MicroVac Vacuum Generator is a combination of a MicroCube Precision Fitting and three appendages: an inlet, a contaminant port, and an outlet. A first stage fits inside the inlet and is disposed coaxially to a second stage that resides within the outlet.
