Latest Patents

One of Hsu's notable patents involves a method of manufacturing photo masks for lithography. This invention entails acquiring circuit pattern data to calculate a pattern density, representing the total pattern area per predetermined area. For areas with a pattern density below a defined threshold, dummy pattern data are generated to optimize the mask drawing process. Using an electron beam from an electron beam lithography apparatus, the patterns are drawn on a resist layer applied to a mask blank substrate. After exposure to the electron beam, the resist layer is developed, ensuring that the dummy patterns do not appear in the final photo mask pattern. This innovative approach streamlines the production process and enhances the quality of photo masks, vital in modern semiconductor applications.
