Latest Patents
Nishida's latest patents include a method of manufacturing a transfer mask and a method of manufacturing a semiconductor device. The first patent focuses on detecting internal defects in a transfer mask using transmitted light quantity distribution data from an inspection apparatus. This innovative approach employs a die-to-die comparison inspection method, where inspection light is directed at different regions of a thin film to obtain transmitted light quantity distributions. By analyzing the differences between these distributions, a selection can be made for a transfer mask that does not exhibit high-density defect regions. The second patent involves a halftone type phase shift mask blank, which features a semitranslucent film pattern and a shielding film pattern on a transparent substrate. This design allows for effective detection of the film patterns based on reflected light when inspected.
