    摘要: In one embodiment, a method for predicting yield during the design stage includes receiving defectivity data identifying defects associated with previous wafer designs, and dividing the defects into systematic defects and random defects. For each design layout of a new wafer design, yield is predicted separately for the systematic defects and the random defects. A combined yield is then calculated based on the yield predicted for the systematic defects and the yield predicted for the random defects.

    摘要: Embodiments of the present invention provide methods and apparatuses for determining factors for design consideration in yield analysis of semiconductor fabrication. In one embodiment, a computer-implemented method for determining factors for design consideration in yield analysis of semiconductor fabrication includes obtaining a geometric characteristic of a defect on a chip and obtaining design data of the chip, where the design data is associated with the defect. The method further includes determining a criticality factor of the defect based on the geometric characteristic and the design data, and outputting the criticality factor.
