    摘要: The method of forming a polysilicon layer is provided. A first polysilicon layer with a first grain size is formed on a substrate. A second polysilicon layer with a second grain size is formed on the first polysilicon layer. The first grain size is smaller than the second grain size. The first polysilicon layer with a smaller grain size can serve as a base for the following deposition, so that the second polysilicon layer formed thereon has a flatter topography, and thus, the surface roughness is reduced and the Rs uniformity within a wafer is improved.

    摘要: An optical critical dimension measuring method, applicable in measuring a pattern, that includes a plurality of polysilicon layers, of a device, is provided. The method includes obtaining a real curve corresponding to the to-be-measured device. Then, determining whether an ion implantation process has been performed on the polysilicon layers, a different module is selected. A correlation process is performed according to the selected module to generate a theoretical curve that correlates with the real curve to obtain a plurality of parameters corresponding to the theoretical curve.
