An apparatus, and particularly, a wafer carrier for polishing the face of a semiconductor wafer are provided. The wafer carrier forms a first cavity which can be pressure controlled to vary the shape of a face of a platen which contacts the wafer during polishing. A second cavity within the first cavity is provided. The second cavity can be independently pressure controlled to form a vacuum for holding the wafer against the platen surface or for forming a pressure stream to separate the wafer from the platen and/or to purge the holes in the surface of the platen. A non-contact displacement sensor capable of measuring a distance between the wafer carrier mount and the platen, may be provided. An endpoint detector capable of detecting a relative surface roughness of the wafer, to determine when the wafer has been sufficiently polished, may also be provided. A ring is peripherally located about an outer edge of the platen, and is mounted and positioned to resist lateral forces on the wafer during polishing.

A method of fabricating a high energy radiation mask, such as a laser ablation mask for manufacturing inkjet printheads, includes a multi-stage evacuation process and/or a step of reducing the deposition rate of silicon dioxide during formation of a dielectric stack. When the multi-stage evacuation procedure is combined with the slower deposition rate of silicon dioxide, the resulting mask has a surprisingly low defect density. In the first embodiment, the evacuation procedure is initiated using a low-rate first evacuation connection. The relatively slow purging of a vacuum chamber in which the dielectric stack is subsequently formed controls turbulence and environmental changes that can generate contamination and water along the surface of the substrate on which the dielectric stack is formed. When a pressure setpoint is reached, a second roughing connection is activated to increase the speed of the procedure. The second connection has a higher maximum rate than the first connection.

A phase-compensating cube corner retroreflector includes three rear reflecting surfaces. The first and the third rear reflecting surfaces can be coated with a phase-compensating film stack that induces 2nπ phase difference upon reflection, where n is an integer including 0. Alternatively, all three rear reflecting surfaces can be coated with a phase-compensating film stack that induces nπ phase difference when handling linearly polarized light, or 2nπ phase difference when handling linearly or circularly polarized light. So coated, the phase-compensating cube corner preserves the polarization orientation and ellipticity of the incident light. Such a phase-compensating cube corner can be used to improve the accuracy of distance-measuring interferometers. The cube corner directs light to and from other optical elements, including a polarizing beam-splitters, mirrors, and quarter-wave plates.

A method for electronically magnifying a target object with an imaging device. The method includes obtaining a full view image of the target object, where the full view image is focused. The method further includes moving the imaging device in proximity to a portion of the target object and obtaining a key image of the portion of the target object. The method further includes matching the key image to a corresponding portion of the full view image. The method further includes magnifying the corresponding portion of the full view image and displaying the magnified portion of the full view image.

Intelligent product feed systems and product transport methods are presented in which an array of variable speed transport modules is positioned between an input transport mechanism and an output mechanism, with the individual module speeds being controlled by a model-based planner to transport products delivered in an uncertain fashion by the input transport mechanism to the output mechanism synchronized and oriented according to a specified product configuration.

A system and method for interfacing a Web browser widget with social indexing is provided. Electronically-stored articles and a plurality of social indexes that are each associated with a social community are maintained. Each social index includes topics that each relate to at least one such article and a topic model for each topic. A widget remotely executing on a Web browser is interfaced and a request identifying one such social community is accepted. A Web page currently in view on the Web browser is identified and content included in the Web page is obtained. The social index for the social community is obtained. The topic models in the social index are evaluated against the content. Topically-relevant information based on the topics in the social index corresponding to those of the topic models matched to the content is selected. The topically-relevant information is provided to the widget arranged for presentation.
