Latest Patents

Ebata's latest patents include a diffraction grating, a method for manufacturing diffraction gratings, and a photomask. The objective of his inventions is to enhance the performance of diffraction gratings. In his method, a molding member is prepared, which includes a substrate and a resist pattern with grooves. These grooves alternate between bottom portions and top portions, extending in a specific direction. The intervals between adjacent bottom portions change stepwise, allowing for precise manufacturing. A metal film is then formed on the resist pattern, which is later peeled off to create a surface shape that is the reverse of the original resist pattern. Additionally, he has developed a manufacturing method for concave diffraction gratings, which enables easy and accurate alignment of groove intervals with a convex fixing substrate.
