Latest Patents

Amano's latest patents include innovations related to phase-shifting photomask blanks and the methods for producing them. His work involves a reactive sputtering technique that allows for the formation of a uniform thin phase-shifting photomask blank. This process utilizes NO gas as the reactive gas and a target composed of a mixture of molybdenum and silicon. The transparent substrate serves as the thin film-forming substrate, enabling the creation of a light-transmitting film that can effectively transmit light rays without contributing to exposure. The film is formed through an opening that ensures even regions with lower deposition rates contribute to the film formation. The resulting phase-shifting photomask blank undergoes a patterning treatment to create a functional photomask.
