  • Patent number: 9006003
    Abstract: A method of detecting bitmap failure associated with physical coordinates is provided. In the method, data of wafer mapping inspection are obtained first, and the data include images of defects in each of layers within a wafer and a plurality of physical coordinates of the defects. Thereafter, a bitmap failure detection is performed to obtain digital coordinates of failure bits within the wafer. The digital coordinates are converted into a plurality of physical locations, and the physical locations are overlapped with the physical coordinates so as to rapidly obtain correlations between the failure bits and the defects.

  • Patent number: 8607171
    Abstract: A system and method for modifying an integrated circuit (IC) layout includes performing a correction process, such as an optical proximity correction (OPC) process, only on regions within designated blocks that are defined around respective modified structures. An IC layout can be compared to a modified version of the IC layout to detect modified structures. One or more large blocks can then be defined around respective modified structures. A correction process can then be performed on only the one or more large blocks. Small blocks within respective large blocks can then be extracted from the modified IC layout and merged with the original IC layout to generate a final modified and corrected IC layout.
