Title:
EXPOSURE PELLICLE FILM, PELLICLE, EXPOSURE ORIGINAL, EXPOSURE DEVICE, AND METHOD FOR MANUFACTURING EXPOSURE PELLICLE FILM
Document Type and Number:
WIPO Patent Application WO/2021/210432
Kind Code:
A1
Abstract:
An exposure pellicle film includes a carbon nanotube film, the carbon nanotube film containing carbon nanotubes, the carbon nanotube film having an EUV light transmittance of 80% or above at a wavelength of 13.5 nm, and the carbon nanotube film having a thickness of 1-50 nm inclusive. When the carbon nanotube film is positioned on a silicon substrate and the reflectance of the positioned carbon nanotube film is measured under the following conditions using a reflection spectroscopic film thickness gauge, 3σ of the reflectance is 15% or below. Diameter of measurement points: 20 μm; reference measurement wavelength: wavelength 285 nm; number of measurement points: 121; distance between center points of adjacent measurement points: 40 μm
