  • Publication number: 20220168865
    Abstract: A double-side polishing method including: disposing a wafer between a polishing pad attached to an upper surface of a lower turn table and a polishing pad attached to a lower surface of an upper turn table provided above the lower turn table; and polishing both sides of the wafer. An absolute value of a difference between a gap at inner circumferential portions of the two polishing pads and a gap at outer circumferential portions thereof is defined as a pad gap. The pad gap is larger when the both sides of the wafer are polished than when the two polishing pads are dressed. This provides a double-side polishing method that simultaneously achieves enhancement of quality level (processing precision) and extension of cloth life.

  • Patent number: 11327719
    Abstract: A generation means 11 generates a uniform random number between 0 and a first probability, which is a probability of a stochastic variable becoming a value within a predetermined interval in a positive range in the first discrete distribution. When a uniform random number less than or equal to a second probability is generated, the second probability being a probability of the stochastic variable becoming a value within a predetermined interval in a second discrete distribution, which is a discrete Gaussian distribution on a one-dimensional lattice the center of which is the origin, the selection means 12 selects, as a random number generation method, an accumulation method in which a functional value defining the second discrete distribution is used. When a uniform random number greater than the second probability is generated, the selection means 12 selects a rejection sampling method as the random number generation method.

  • Publication number: 20220134874
    Abstract: In the lid opening and closing device, the rotating body at the initial position rotates to one side in the rotation direction, so that the lock member is disengaged from the first link. Further, the first link and the rotating body are provided with a differential connecting mechanism, and the differential connecting mechanism connects the rotating body and the first link to operate the link mechanism at the retracted position after the lock member is disengaged from the first link, when the rotating body is rotating. As a result, the differential connecting mechanism imparts a time difference between the two operations of the rotating body. Therefore, the lock member and the link mechanism can be operated by rotationally driving the rotating body by a single actuator.
