Abstract: A method for predictably cleaning the contact elements and support hardware of a tester interface, such as a probe card and a test socket, while it is still in manual, semi-automated, and automated handling device and the electrical test equipment is disclosed. In the method, a cleaning device is loaded into wafer prober or packaged device handler and the pin contact elements and support hardware are contacted by the cleaning device.

Abstract: A cleaning wafer or substrate for use in cleaning, or in combination with, components of, for example, integrated chip manufacturing apparatus. The cleaning substrate can include a substrate having varying predetermined surface features, such as one or more predetermined adhesive, non-tacky, electrostatic, 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 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 adapted to accomplish a variety of functions, including abrading or polishing. The cleaning substrate may be made by a novel method of making, and it may then be used in a novel method of use I 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 may be placed within the prober or tester/handler similar to a wafer containing semiconductor dies to be tested so that the probe elements of the testing machine contact the cleaning medium periodically to remove debris and/or reshape the tips of the probe elements.
