  • Publication number: 20230110750
    Abstract: A carrier has a plate-shaped carrier body that has an inner hole and is made of a first material, and an insertion member that is shaped such that the insertion member fits between the substrate and an inner circumference of the inner hole, that has a substrate holding hole, and that is made of a second material that is different from the first material. The insertion member has a region that bulges toward the carrier main body side, and when a radius of an inscribed circle inscribed to an inner circumference of the substrate holding hole of the insertion member is R, the center of gravity of the insertion member is located 0.1×R or more away from the center of an inner circumferential shape of the substrate holding hole of the insertion member.

  • Patent number: 8745555
    Abstract: Methods for designing and manufacturing an integrated circuit are disclosed, in which the physical design process for a standard cell or cells utilizes a preferred diagonal direction for minimum-width patterns on at least one layer, where the standard cell or cells are used in the layout of an integrated circuit. The methods also include forming the patterns on a photomask using model-based fracturing techniques with charged particle beam simulation, and forming the patterns on a substrate such a silicon wafer using the photomask and an optical lithographic process with directional illumination which is optimized for the preferred diagonal direction.

  • Patent number: 8426832
    Abstract: The present invention increases the number of characters available on a stencil for charged particle beam lithography. A stencil for charged particle beam lithography is disclosed, comprising two character projection (CP) characters, wherein the blanking areas for the two CP characters overlap. A stencil is also disclosed comprising two CP characters with one or more optional characters between the two characters, wherein the optional characters can form meaningful patterns on a surface only in combination with one of the two characters. A stencil is also disclosed wherein the blanking area of a CP character extends beyond the boundary of the stencil's available character area. Methods for design of the aforementioned stencils are also disclosed.

  • Patent number: 6938226
    Abstract: A 7-track standard cell library having a layout architecture that is designed for fabrication technologies having design rules of 0.12 microns or smaller. The cells are laid out using a routing grid having horizontal and vertical grid spacings of 0.4 microns, such that the height of each 7-track standard cell is 2.8 microns (i.e., seven track spacings based on a horizontal grid spacing of 0.4 microns). Power rails are implemented using M1 structures. The seven-track cell height is divided into four tracks on the P-side and three tracks on the N-side. Complex cells include one internal connection line (structure) formed using the third metal layer (M3) that is introduced in a predetermined track (e.g., the second track from the top of the cell) to facilitate the seven-track layout.
