Latest Patents

One of Goto's notable inventions is the polarized light irradiation apparatus. This apparatus is designed to prevent the reduction of the extinction ratio of polarized light when there is a change in the direction of polarization. It achieves this by utilizing at least two plane mirrors and forming a protection layer on the surface of the second mirror. The selection of material and optical thickness is crucial, as it ensures that the phase shifts of the polarization components meet specific conditions, thereby maintaining the integrity of the polarized light.

Another significant patent is the process for positioning a mask relative to another mask without the use of a dummy. This innovative process allows for the use of multichromatic light as a light source for alignment, eliminating the need for aberration correction. The device developed for this process utilizes projection lenses that are telocentric, ensuring precise alignment of the masks during operation.
