Abstract: A cleaning wafer or substrate for use in cleaning, or in combination with, components of, for example, integrated chip manufacturing equipment. The cleaning substrate can include a substrate having varying predetermined surface features, such as one or more predetermined adhesive, non-tacky, electrostatic, or projection, depression, or other physical sections. The predetermined features can provide for more effective cleaning of the components with which they are used, such as in an integrated chip manufacturing apparatus in the place of the integrated chip wafer. The cleaning substrate can be urged into cleaning or other position by vacuum, mechanical, electrostatic, or other forces. The cleaning substrate can be adapted to accomplish a variety of functions, including abrading or polishing. The cleaning substrate may made by a novel method of making, and it may then be used in a novel method of use in combination with chip manufacturing apparatus.

Abstract: The cleaning device may clean probe elements. The probe elements may be the probe elements of a probe card testing apparatus for testing semiconductor wafers or semiconductor dies on a semiconductor wafer or the probe elements of a handling/testing apparatus for testing the leads of a packaged integrated circuit. During the cleaning of the probe elements, the probe card or the handler/tester is cleaned during the normal operation of the testing machine without removing the probe card from the prober. The cleaning device has a working surface with a particular characteristic (a matte finish or a conductive material) so that a prober is capable of automatically determining the location of the working surface of the cleaning device and therefore operate in an automatic cleaning mode.
