摘要： A conformal disk holder for holding a rotating disk against a surface of a polishing pad is described. The conformal disk holder can be used for any polishing apparatus, but is particularly suited for use in a CMP pad conditioning disk. The conformal disk holder is constructed by a cover member, a flexural plate member and a base member. The flexural plate member has a center protrusion with a downwardly facing convex surface for intimately engaging an upwardly facing concave surface on a center protrusion of the base member. The intimate engagement between the convex surface and the concave surface allows at least a 5° tilt of the base member from a horizontal plane, and preferably allows a tilt between about 5° and about 30°.

摘要： A system and method for providing laser diodes with broad spectrum is described. GaN-based laser diodes with broad or multi-peaked spectral output operating are obtained in various configurations by having a single laser diode device generating multiple-peak spectral outputs, operate in superluminescene mode, or by use of an RF source and/or a feedback signal. In some other embodiments, multi-peak outputs are achieved by having multiple laser devices output different lasers at different wavelengths.

摘要： A method for executing computer programs in accordance with a preset priority is provided. The method is applicable to a computer system connecting to a data storage, a plurality of device selection buttons, and a plurality of multimedia players. The data storage is installed with a plurality of device drivers, a plurality of device application programs, and a program execution priority table. The program execution priority table defines correspondence between the device selection buttons and the multimedia players, and the priority order of execution of the device drivers and the device application programs of the multimedia players. When the computer detects any device selection button is pressed, the computer executes the device drivers and the device application programs corresponding the multimedia player in the priority order defined by the program execution priority table.

摘要： A thin-film optical recording medium and compatible materials is disclosed. When the transparent layer and the reflecting layer of the present invention are exposed to a light beam, the two layers react to form a semi-transparent reflective alloy/compound area. The presence of such area (1) decreases the effective optical thickness of the transparent layer and/or (2) forms a region of changed optical n & k and/or (3) changes the optical polarization angle. At least one of the above three effects produces an optical contrast before and after the recording from which the signal modulation required for reading the optical media can be derived. The present invention allows high-density, high-resolution, high-speed recording of data that is highly compatible with the full visible-light spectrum.
