  • Patent number: 10534258
    Abstract: A method for semiconductor structure design includes performing, by a processor, error processing of an initial design file layout. The processor further detects a tip-to-tip (T2T) structure design violation at a design cell boundary for a metal layer above (Ma) a via (Vx) at a tip of the Ma for the initial design file layout for a semiconductor structure based on a library of pattern rules. Upon detection of the T2T structure design violation, the processor retargets the Vx for generating a resulting design file layout of the semiconductor structure.

    Abstract: Aspects describing modified self-aligned quadruple patterning (SAQP) processes using cut pattern masks to fabricate integrated circuit (IC) cells with reduced area are disclosed. In one aspect, a modified SAQP process includes disposing multiple mandrels. First spacers are disposed on either side of each mandrel, and second spacers are disposed on either side of each first spacer. A cut pattern mask is disposed over the second spacers and includes openings that expose second spacers corresponding to locations in which voltage rails are to be disposed. The voltage rails are formed by removing the second spacers exposed by the openings in the cut pattern mask, and disposing the voltage rails in the corresponding locations left vacant by removing the second spacers. Routing lines are disposed over routing tracks formed between each set of the remaining second spacers to allow for interconnecting of active devices formed in the IC cell.
