    Abstract: Provided is a novel chamber effluent monitoring system. The system comprises a chamber having an exhaust line connected thereto. The exhaust line includes a sample region, wherein substantially all of a chamber effluent also passes through the sample region. The system further comprises an absorption spectroscopy measurement system for detecting a gas phase molecular species. The measurement system comprises a light source and a main detector in optical communication with the sample region through one or more light transmissive window. The light source directs a light beam into the sample region through one of the one or more light transmissive window. The light beam passes through the sample region and exits the sample region through one of the one or more light transmissive window. The main detector responds to the light beam exiting the sample region. The system allows for in situ measurement of molecular gas impurities in a chamber effluent, and in particular, in the effluent from a semiconductor processing chamber. Particular applicability is found in semiconductor manufacturing process control and hazardous gas leak detection.

    Abstract: A light sampling system for sampling scattered light from mirrors in an optical switch. The system includes four basic components: an imaging lens, a multi-channel liquid crystal light valve (LCLV), a collecting lens, and a light sensor. Light scattered by each mirror, is collected by the imaging lens, which re-images the light onto the LCLV. The LCLV is divided into multiple regions, one for each mirror to be monitored. Each region can independently be made opaque (nullclosednull) or transparent (nullopennull) to light reaching it. Light passing through all open regions of the LCLV is collected by the collecting lens, which focuses the light onto the light sensor. The light sensor registers a response to light passing through the LCLV. Each region of the LCLV can be programmed to be open or closed for any length of time, in any combination or sequence with any other region or regions, depending upon how the user wishes to monitor the scattered light. The system is particularly useful for individually sampling scattered light from each of multiple mirrors.

    Abstract: A ground contamination detector has a duct (21) having an annular opening (21a). The annular opening blows air toward the ground (1) to form an air curtain that defines an enclosed space (2A) between the duct and the ground. The detector also has a pipe (23) having a nozzle that opens in the enclosed space and jets heated air toward the ground, to promote the evaporation of noxious substance (3) and diffuse the evaporated gas in the enclosed space. The detector also has a suction pipe (24) to suck the evaporated gas from the enclosed space and a sensor (25) to analyze the sucked gas. The enclosed space formed by the air curtain defines a detection area on the ground, and the detector collects and analyzes contaminants in the enclosed space in a noncontact way. The detector is installable on a vehicle, to efficiently detect the presence and position of contaminants on the ground in real time.

    Abstract: An apparatus for simulating a blackbody utilizes several plates to absorb and reflect electromagnetic radiation. Electromagnetic radiation entering the apparatus from a certain view is reflected from one plate to another, until the direction of travel of the electromagnetic radiation is reversed. Each time the electromagnetic radiation is reflected, the majority of the electromagnetic radiation is absorbed resulting in a negligible amount of incoming electromagnetic radiation escaping the apparatus.

    Abstract: A multi-charged particle beam tool for semiconductor wafer inspection or lithography includes an array of electron beam columns, each having its own electron or ion source. The objective lenses of the various electron beam columns, while each has its own pole piece, share a common single magnetic coil which generates a uniform magnetic field surrounding the entire array of electron beam columns. This advantageously improves the spacing between the beams while providing the superior optical properties of a strong magnetic objective lens. When used as an inspection tool, each column also has its own associated detector to detect secondary and back-scattered electrons from the wafer under inspection. In one version the gun lenses similarly have individual pole pieces for each column and share a common magnetic coil.

    Abstract: A virtual blackbody radiation system (10) includes a light-emitting unit (1) including an LED driven by a fixed current, a light-receiving unit (2) including a sapphire rod, and an optical unit (3) including lenses (31, 32) for converging light emitted by the light-emitting unit in a convergent light. A cylindrical member (41)included in the optical unit (3)can be moved along the optical axis by a servomotor (42) included in a focus adjusting unit (4) for positional adjustment. The focus of convergent light relative to the light-receiving unit (2) can be adjusted by moving the lens (32) disposed in the cylindrical member (41) along the optical axis relative to the light-receiving unit (2). The intensity of the convergent light on the light-receiving unit (2) can be adjusted to the intensity of predetermined blackbody radiation. Thus, the virtual blackbody radiation system (10) is able to obtain light of a desired intensity without changing the driving current for driving a light source; consequently, the life time of the light source can be extended and the stability of radiation can be improved.
