  • Publication number: 20250061260
    Abstract: An integrated circuit includes a plurality of routing lines extending along a first direction, the plurality of routing lines being separated in the first direction by integral multiples of a nominal minimum pitch. The integrated circuit includes a plurality of standard cells, at least one of the plurality of standard cells having a first boundary coinciding with a routing line of the plurality of routing lines, and a second boundary offset from each of the plurality of routing lines.

  • Patent number: 7078149
    Abstract: A method for fabricating an optical recording medium is provided. A dye layer is formed on a molded substrate by spin-coating. A reflection layer is formed on the dye layer by sputtering so that the optical disc has enough reflection rate. The dye layer comprises a cyanine type dye and an azo metal chelate compound selected from the formula (I): wherein M is a metal ion; R1 is a hydrogen atom, a linear or branched alkyl group containing 1 to 6 carbon atoms, amino group, alkyl amino group or toluidinyl group; R2 is a hydrogen atom, a hydroxyl group, a halogen atom, an ether group, an ester group or a linear or branched alkyl group containing 1 to 6 carbon atoms; R3 is a hydrogen atom or a linear or branched alkyl group containing 1 to 6 carbon atoms; R4 is a hydrogen atom, a halogen atom or a linear or branched alkyl group containing 1 to 6 carbon atoms; A1 is a heterocyclic derivative group constituted by carbon atoms and nitrogen atoms.
