  • Patent number: 7291063
    Abstract: The present invention relates to an article for altering a surface of a workpiece, or a polishing pad having a window. In particular, the polishing pad includes a polyurethane urea material wherein the polyurethane urea material contains cells which are at least partially filled with gas. The polyurethane urea material can be prepared by combining polyisocyanate and/or polyurethane prepolymer, hydroxyl-containing material, amine-containing material and blowing agent. The polishing pad according to the present invention is useful for polishing articles, and is especially useful for chemical mechanical polishing or planarization of microelectronic and optical electronic devices such as but not limited to semiconductor wafers. The window of the polishing pad is at least partially transparent and thus, can be particularly useful with polishing or planarizing tools that are equipped with through-the-platen wafer metrology.

  • Patent number: 7249492
    Abstract: A method and device are provided for measuring and/or adjusting the cleaning performance of a cleaning liquid. One method of the invention includes determining a control value (i.e., the number of drops of the cleaning liquid to provide a selected volume) indicative of when the cleaning performance of the cleaning liquid is at or approaching an unacceptable level. At least one substrate can be contacted with the cleaning liquid and a drop number for the cleaning liquid (i.e., the number of drops of the cleaning liquid to provide the selected volume) again measured. At least one cleaning agent, such as at least one surfactant, can be added to the cleaning liquid when the measured drop number is at or near the control value. In one embodiment, the cleaning agent can be added until the measured drop number is at or near a baseline drop number for the cleaning liquid (i.e., the number of drops of the cleaning liquid when cleaning performance is acceptable).

The photochromic articles demonstrate a photochromic response when activated behind an ultraviolet blocking transparency such as an automotive windshield. For example, the photochromic articles retain at least 12 percent of the activation measured as change in optical density or delta OD under outdoor simulating conditions in the Outdoor Test when tested under conditions simulating an eyeglass wearer behind an automotive windshield in the Behind the Windshield Test.
