Latest Patents
Iwashita holds a patent for a "Method of manufacturing a transfer mask and method of manufacturing a semiconductor device." This patent addresses the detection of internal defects in a transfer mask using transmitted light quantity distribution data from an inspection apparatus. The process involves a die-to-die comparison inspection method, where inspection light is directed at two regions of a thin film to obtain respective transmitted light quantity distributions. A predetermined-range difference distribution is then created by plotting coordinates based on the comparison of these distributions. This method allows for the selection of a transfer mask that does not exhibit high density of plotting in the predetermined-range difference distribution.
