Abstract: An improved system and method for purging a microenvironment to desired levels of relative humidity, oxygen, or particulates through the implementation of a purge gas delivery apparatus and method that provides even distribution of the purging gas within the microenvironment. A substrate container has a tower therein with a fluid flow passageway extending the length of the tower. Apertures with porous media between the aperture and fluid flow passageway regulate the volume and pressure of air discharging at each aperture. Alternatively, the tower may be formed of a porous tubular polymeric material. A sleeve may direct the discharge purge gas in the interior.

Abstract: Material management systems and methods include material storage vessels with information (e.g., electronic information) storage. Information may be communicated from a storage device to a process tool controller and employed to set or adjust a process tool operating parameter. Material information may be determined by remote analysis and subsequently communicated to an electronic information storage device of a vessel containing such material. Location and movement of material storage vessels within a customer facility may be automatically tracked, with further transfer of material-specific information. Product information may be associatively stored with material-specific information utilized in product manufacture.

Abstract: An optical sensor apparatus includes an optically transmissive structure having planar first, second, and third faces, two or more light sources located outside the structure adjacent the first face, and a photodetector array located outside the prism adjacent the first face. The structure, light sources, and photodetector array are configured such that light from the light sources that is totally internally reflected at an optical interface between the prism and a sample outside the structure proximate the second face is reflected at the third face and incident on a portion of the photodetector array that depends on a refractive index of the sample. The light sources are positioned with respect to the structure and photodetector array such that the totally internally reflected light from each light source corresponds to a different range of refractive index of the sample and maps to a corresponding portion of the photodetector array.

Abstract: Embodiments of the present invention provide I/O systems, methods, and devices for interfacing pump controller(s) with control device(s) which may have different interfaces and/or signaling formats. In one embodiment, an I/O interface module comprises a processor, a memory, and at least two data communications interfaces for communicating with a pumping controller and a control device. The I/O interface module can receive discrete signals from the control device, interpret them accordingly and send the packets to the pump controller. The pump controller reads the packets and takes appropriate actions at the pump. The I/O interface module can interpret packets of data received from the pump controller and assert corresponding discrete signals to the control device. The I/O interface module is customizable and allows a variety of interfaces and control schemes to be implemented with a particular multiple stage pump without changing the hardware of the pump.
