  • Publication number: 20200379337
    Abstract: A blankmask includes a transparent substrate, a phase-shift film, and a light-shielding film. The phase-shift film for example has a transmissivity of 30˜100%, and in this case the light-shielding film has a thickness of 40˜70 nm and a composition ratio of 30˜80 at % chromium, 10˜50 at % nitrogen, 0˜35% oxygen, and 0˜25% carbon. A structure where the light-shielding film and the phase-shift film are stacked has an optical density of 2.5˜3.5. Thus, CD deviation is minimized when the light-shielding film is etched in a manufacturing process for a photomask.
