    摘要: The object of the present invention is to establish a technology for directly evaluating polishing pad surface conditions, to allow high-precision CMP process management, and to improve process throughput. The pad surface is illuminated with light. The intensity of reflected light or fluorescence from the illuminated area or an intensity distribution image is used directly evaluate the pad surface condition. Based on the results of this evaluation, conditioning conditions for a conditioner are optimized, thus allowing high-precision CMP processing while maintaining good pad surface conditions.

    摘要: A projecting apparatus for forming an image of a mask on a wafer by a projector of a unit magnification reflection system having a concave spherical mirror and a convex spherical mirror. The distance from the projector to the mask or the upper side of a mask holder for holding the mask and the distance from the projector to the wafer are measured. An error of the image-forming position is computed from the distance measurements. At least one of the mask, the wafer and the projector is moved along the direction of projection in a manner to eliminate the error of the image-forming position computed, thus attaining automatic focus adjustment.

    摘要: A continuous sputtering apparatus comprising a main vacuum chamber, one loading station and a plurality of process stations capable of having their pressures controlled separately. The process station includes a sub vacuum chamber capable of being in communication with the main vacuum chamber through an opening and an evacuation port. The loading station and the process stations are arranged to be spaced with equal angles. Substrate holders are provided to face the stations and are rotated by said equal angle in a time. The substrate holder opens and closes the opening of the sub vacuum chamber to serve as a gate valve.
