Patent ID: 7562326

Claim:
A method of generating a standard cell layout and transferring the standard cell layout to a substrate, comprising: using a computer to execute steps of: creating a plurality of leaf cell layouts in a leaf cell layout library; analyzing a circuit of the standard cell layout to obtain an analysis result indicating a plurality of leaf cell layouts able to make up the analyzed standard cell layout; selecting a plurality of leaf cell layout from the leaf cell layout library according to the analysis result; piecing together the leaf cell layouts selected from the leaf cell layout library to generate the standard cell layout; wherein each of the leaf cell layout is rectangular having a long axis and a short axis, the leaf cell layouts are arranged along the short axis in a single row, the leaf cell layouts which form the standard cell layout comprises at least one main leaf cell layout and two boundary leaf cell layouts, and a width of the boundary leaf cell layout is substantially half that of the main leaf cell layout; and wherein the main leaf cell layout is composed of a plurality of grids, each of the o grids has a width of 0.26 microns, and a length of 0.2 microns; and transferring the standard cell layout to the substrate to form an integrated circuit.
