Abstract: An improvement is proposed in the design and manufacturing of the frame-supported pellicle used to protect the photomask- a lithographic template employed in semiconductor manufacturing for creating integrated circuit devices- from airborne contaminants. Addressed, is that the industry's current pellicle frame design always results in the destruction of the frame-supported pellicle and sometimes the photomask itself when- as is frequently the case- defects are found underneath the frame-supported pellicle necessitating its removal to permit photomask repair and/or cleaning. In addition, imperfections in the flatness of the current pellicle frame induce physical distortions in the photomask that result in degradations to the photomask's pattern placement accuracy.

Abstract: The present invention is directed to polishing pads useful in determining an end to the useful wear life thereof. In a simple embodiment of the present invention, a polishing pad that is used with slurries is dyed on one side in a manner that causes the dye to permeate the pad to a limited depth that does not cause total coloring. Another embodiment of the present invention involves a fixed abrasive pad that has fixed abrasives embedded into the pad to a selected depth where at least one color level is within the portion of the pad that contains the fixed abrasives. After dyeing the pad, the pad is attached to the polishing platen. During the polishing operation, a color change signals a time to stop the polishing operation and change the pad. With multiple colors in the pad, limited only by the ability to dye the pad with uniform depth levels, characteristic wear patterns can be observed and adjustments made accordingly to prolong and optimize pad life.

Abstract: An in-duct humidifier has a permeable rectangular pad to be placed in a heated air stream. Water dripping onto the top of the pad is evaporated by the air stream which is passing through the pad to thereby increase its humidity. The pad is held in a frame and the frame is mounted in the humidifier's housing. The frame holds the pad by an arrangement of sloped surfaces and narrow projections to minimize the area of the frame in direct contact with the pad. By minimizing the contact area between the pad and the frame, the amount of water flowing onto the frame and evaporating from the frame is minimized, thereby reducing the rate and amount of minerals dissolved in the water which are deposited on the frame surfaces.
