    摘要: Embodiments described herein provide a method for polishing a substrate surface. The methods generally include storing processing components in multiple storage units during processing, and combining the processing components to create a slurry while flowing the processing components to a polishing pad. A substrate is polished using the slurry, and the thickness of a material layer disposed on the substrate is determined. The flow rate of one or more processing components is then adjusted to affect the rate of removal of the material layer disposed on the substrate.

    摘要: A method and apparatus for extending a polishing article lifetime on a polishing tool with multiple platens is described. The apparatus includes an advanceable roll to roll platen with multiple embodiments of a polishing article to be used thereon. The polishing article is adapted to perform a polishing process by removing conductive and dielectric material from a substrate while minimizing downtime of the polishing tool. In some embodiments, the polishing article may be a dielectric material or a conductive material and is configured to include a longer usable lifetime to minimize replacement and downtime of the tool.

    摘要: Systems for scribing a workpiece incorporate a motorized beam expander to change a laser beam spot size incident on a workpiece. A system includes a frame, a laser coupled with the frame and generating an output to remove material from at least a portion of a workpiece, a beam expander positioned along a path of the laser output and having a motorized mechanism operable to vary a beam expansion ratio applied to the laser output, and at least one scanning device coupled with the frame and operable to control a position of the laser output, after expansion, on the workpiece. The motorized beam expander can be used to selectively vary the width of a laser beam supplied to a scanning device so as to selectively vary the size of the laser beam incident on the workpiece. Alternatively, a variable aperture can be used instead of a beam expander.

    摘要: In-line metrology methods and systems for use with laser-scribing systems used in solar-cell fabrication are disclosed. Such methods and systems can involve a variety of components, for example, a device for measuring the amount of power input to a laser, a power meter for measuring laser output power, a beam viewer for measuring aspects of a laser beam, a height sensor for measuring a workpiece height, a microscope for measuring workpiece features formed by the laser-scribing system, and a system for monitoring a laser-scribing system and annunciating a warning(s) and/or an error message(s) when operational limits are exceeded. In-line metrology methods can also include the processing of output beam reflections so as to track beam drift over time and/or provide for focusing of an imaging device.

In many embodiments, a laser-scribing apparatus includes a frame, a first fixture coupled with the frame, a second fixture coupled with the frame, a laser operable to generate output able to remove material from at least a portion of the workpiece, and a scanning device coupled with the laser and the frame. The first fixture is configured for engagement with a first portion of the workpiece. The second fixture is configured for engagement with a second portion of the workpiece. When the workpiece is engaged by the first and second fixtures the workpiece is substantially vertically oriented. The scanning device is operable to control a position of the output from the laser relative to the workpiece.
