  • Patent number: 10896828
    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.

  • Patent number: 10406568
    Abstract: A cleaning film designed to remove foreign matter and particulates from working surfaces of cleaning wafers used in semiconductor processes. These processes include wafer sort test for cleaning of probe card pins and FEOL tooling for cleaning during wafer handling equipment and wafer chucks. The debris collected on the cleaning wafer working surfaces is removed by the particle removal film allowing the debris and foreign matter to be discarded. The use of the cleaning film allows the operator to refresh the cleaning wafer without use of an outside vendor and eliminates wet washing and the use of solvents in the cleaning process.

  • Patent number: 8801869
    Abstract: A cleaning device for cleaning pin contact elements and support hardware in a semiconductor testing apparatus that has a cleaning layer with a predetermined configuration appropriate for the particular pin contact elements and a substrate having a configuration to be introduced into the testing apparatus during the normal testing operating of the testing apparatus. The cleaning layer secured to the substrate has predetermined characteristics that cause the pad to clean debris the pin contact elements and support hardware when the pin contact elements and support hardware contact the pad during the normal operation of the testing machine.
