  • Publication number: 20250061261
    Abstract: The present disclosure provides a method and an apparatus for arranging electrical components within a semiconductor device, and a non-transitory computer-readable medium. The method includes (a) providing a first layout including a plurality of cells placed therein; (b) generating a second layout by performing a first set of calculations on the first layout such that cell congestions in the first layout is eliminated from the second layout; (c) generating a third layout by performing a second set of calculations on the second layout such that the total wire length of the third layout is less than that of the second layout; and (d) iterating the operations (b) and (c) until a target layout conforming a convergence criterion.

  • Patent number: 6695921
    Abstract: An improved hoop support for semiconductor wafers reduces contamination of the wafer during edge beveling operations through the use of support pins that make only line contact with the wafer. The support pins are spaced around the periphery of the hoop and possess a triangular cross section. Two intersecting sides of the pins form an edge that defines the line contact with the wafer. These intersecting sides are preferably inclined relative to the wafer at an angle of between 60 and 80 degrees.
