Latest Patents

Hoshino's latest patents include a self-cleaning method for aligners and a phase difference specifying method. The self-cleaning method involves a reflecting plate with a convex lens portion that is set in an original plate holder. Exposure light rays are irradiated from a light source, and the lens portion is coated with a reflective film. This setup allows the light rays to be reflected, diffused, and emitted onto the surface of a condenser lens, effectively breaking down and removing contaminants. The method also ensures that contaminants in areas other than the normal exposure path are cleaned.

The phase difference specifying method features a phase shift mask with first and second mask patterns. The first mask pattern acts as a backing film that enables the formation of a first optical image on a substrate. This image creates a resist pattern with a width that varies based on the distance between the mask and the substrate. The second mask pattern, a semi-transmissive film, allows for the formation of a second optical image, which also results in a resist pattern with a width that changes depending on specific parameters. The duty ratio of the second mask is carefully set to ensure that the width variations of both optical images are synchronized.
