Patent ID: 7501305

Claim:
A method for forming a deposited film containing microcrystalline silicon on a moving substrate by plasma-enhanced CVD, the method comprising a step of: forming a deposited film containing microcrystalline silicon on a moving substrate by plasma-enhanced CVD under conditions such that when a deposited film having a thickness of 300 nm or more is formed on a substrate while the substrate is in a stationary state, an area of the microcrystalline silicon region in which an intensity of Raman scattering attributed to a crystalline substance in the deposited film is equal to or higher than three times an intensity of Raman scattering attributed to an amorphous is 50% or more of the total area based on the area of the microcrystalline silicon region and the area of a region composed of the amorphous, wherein the area of microcrystalline silicon region in which the intensity of Raman scattering attributed to the crystalline substance in the deposited film is equal to or higher than three times the intensity of Raman scattering attributed to amorphous is determined by color or reflectivity corresponding to microcrystalline silicon.
