Abstract: A polysilicon layer including an amorphous polysilicon layer and a crystallized polysilicon layer is provided. The crystallized polysilicon layer is disposed on the amorphous polysilicon layer. Besides, the amorphous polysilicon layer has a first grain size, the crystallized polysilicon layer has a second grain size, and the first grain size is smaller than the second grain size. The amorphous polysilicon layer with a smaller grain size can serve as a base for the following deposition, so that the crystallized polysilicon layer formed thereon has a flatter topography, and thus, the surface roughness is reduced and the Rs uniformity within a wafer is improved.
