Latest Patents
One of Toshiyuki Ohishi's latest patents is a process for producing diffraction gratings. This innovative process involves several steps, including the formation of a coating layer on a first diffraction grating layer made of resin on a substrate. The method ensures that the first diffraction grating layer remains undamaged during the coating process. After forming the coating layer, a portion of it is removed through etching to create a second diffraction grating layer that has a reverse phase compared to the first. The first diffraction grating layer is then removed, and the substrate is etched using a mask made from the second diffraction grating layer. This technique allows for the easy production of diffraction gratings with a reverse phase. Additionally, if the first diffraction grating layer is retained, both layers can be used as a mask to produce a diffraction grating with a period that is half the size of the first grating layer.
