Latest Patents

One of Matsuda's latest inventions is a photomask and a method of manufacturing it using a trapezoidal configuration. This photomask is composed of a transparent substrate with a light shielding film that is intricately designed. The film features a bottom surface that contacts the substrate, a side face at an acute angle, and an upper face that runs parallel to the bottom yet at an obtuse angle to the side face. This unique structure enables the accurate formation of a phase shift portion around the film's perimeter, effectively enhancing pattern resolution by minimizing the negative impact of reflective light.

Additionally, the manufacturing method for this photomask involves several critical steps. A trapezoidal pattern is created on the transparent substrate, along with the application of a transparent film at temperatures not exceeding 250 degrees Celsius. This process plays a vital role in suppressing thermal distortion within the light shielding film, thus ensuring robustness and precision in the final product.
