摘要： Light scattered from illuminated spot on a patterned wafer is first passed through a di-electric filter and then by an optical fiber bundle to a detector. The di-electric filter controls the aperture of the light that is passed to a desired azimuth angle and the optical fiber further limits the aperture.

摘要： There is disclosed numerous embodiments of a method and apparatus for a particle scanning system and an automatic inspection system. In each of these a particle beam is directed at the surface of a substrate for scanning that substrate. Also included are a selection of detectors to detect at least one of the secondary particles, back-scattered particles and transmitted particles from the substrate. The substrate is mounted on an x-y stage to provide it with at least one degree of freedom while the substrate is being scanned by the/particle beam. The substrate is also subjected to an electric field on it's surface to accelerate the secondary particles. The system also has the capability to accurately measure the position of the substrate with respect to the charged particle beam. Additionally, there is an optical alignment means for initially aligning the substrate beneath the,particle beam means. To function most efficiently there is also a vacuum means for evacuating and repressurizing a chamber containing the substrate. The vacuum means can be used to hold one substrate at vacuum while a second one is being loaded/unloaded, evacuated or repressurized. Alternately, the vacuum means can simultaneously evacuate a plurality of substrates prior to inspection and repressurize of the same plurality of substrates following inspection. In the inspection configuration, there is also a comparison means for comparing the pattern on the substrate with a second pattern.

摘要： A turntable is rotated to wind the tape of a taped program thereon in equal lengths per revolution thereof. Each equal winding forces the preceeding windings inwardly on the turntable to assume progressively curving paths as the respective windings recede from the periphery of the turntable. Pressure pads are equally spaced around the periphery of the turntable and rotate therewith. The pressure pads extend radially, and frictionally engage the top edges of the tape windings which follow increasingly curved paths therebetween as the equal windings are forced inwardly by succeeding equal windings. The ends of the tape are connected leaving a portion of the closed loop formed thereby for engagement by associated apparatus and rendition thereby of the taped program. Since all of the windings on the turntable are of the same length per rotation thereof, tape can be simultaneously wound on and off the turntable as it is rotated with no slippage and friction between windings, and as the beginning and end of the taped program are joined, the program can be repeated for as many performances as desired, with only monitoring for mechanical failures required.

摘要： Systems and methods for automatic throttling of resources in an information handling system are disclosed. A method may include determining whether a first throttling condition exists, the first throttling condition existing when a chassis management controller fails to communicate a clock or synchronization signal to one or more devices in an information handling system chassis for a particular duration of time. The method may also include determining whether a second throttling condition exists, the second throttling condition existing when the chassis management controller fails to communicate data to one or more devices in the information system handling chassis. The method may further include throttling a resource in the information handling system chassis if at least one of the first throttling condition and the second throttling condition exists.

摘要： Methods and systems produce flattening layers associated with nitrogen-containing quantum wells and prevent 3-D growth of nitrogen containing layers using controlled group V fluxes and temperatures. MEE (Migration Enhanced Epitaxy) is used to form a flattening layer upon which a quantum well is formed and thereby enhance smoothness of quantum well interfaces and to achieve narrowing of the spectrum of light emitted from nitrogen containing quantum wells. MEE is performed by alternately depositing single atomic layers of group III and V materials at a given group V flux and then raising the group V flux to saturate the surface of the flattening layer with the group V material. A cap layer is also formed over the quantum well. Where nitrogen is used, the systems incorporate a mechanical means of preventing nitrogen from entering the MBE processing chamber, such as a gate valve.

摘要： This disclosure concerns devices such as DBRs, one example of which includes at least one first mirror layers having an oxidized region extending from an edge of the DBR to an oxide termination edge that is situated greater than a first distance from the edge of the DBR. The DBR also includes at least one second mirror layer having an oxidized region extending from the edge of the DBR to an oxide termination edge that is situated less than a second distance from the edge of the DBR, such that the first distance is greater than the second distance. Additionally, a first mirror layer includes an oxidizable material at a concentration that is higher than the concentration of the oxidizable material in any of the second mirror layers. Finally, a first mirror layer is doped with an impurity at a higher level than one of the second mirror layers.
