    摘要: PROBLEM TO BE SOLVED: To provide a reflective mask capable of mask inspection by pattern comparison on a layout in a mode of scan exposure by injecting exposure light slantly to the mask, and its inspection method.
    SOLUTION: The reflective mask for irradiating the exposure light slightly incident to a mask surface over a predetermined exposure area and projecting light reflected on the mask surface to a wafer for scan exposure includes a plurality of rectangular chip regions 11a-11f containing the same mask patterns arranged in a scanning direction 12. When shape correction is made depending on a distance from the center line of an exposure area 21 (azimuth angle θ), the two chip regions 11a and 11b have the identical mask patterns after the shape correction. Thus the identical patterns can be compared with each other on the layout to perform die-to-die inspection for defect inspection of the mask pattern.

    摘要: PROBLEM TO BE SOLVED: To provide mask designing techniques capable of shortening the increased OPC (Optical Proximity Correction) processing time, shortening the manufacture TAT (Turn Around Time) of a semiconductor device, thereby reducing cost. SOLUTION: A cell library pattern constituting a basic configuration of a semiconductor circuit pattern is preliminarily subjected to an OPC processing for the layout of a single pattern, and the processed cell library pattern is used to produce a semiconductor chip. A plurality of cell libraries are laid to design a mask pattern and the correction amount by the OPC applied to the cell library is changed by considering the influences of cell library patterns laid in the periphery. Further, a group of cells in the identical layout of the objective cell as well as peripheral cells is extracted and registered as a cell set, so that OPC on identical cell sets is carried out not by repeating computation but by copying.
