Claim 22:
23. The physical analysis method according to claim 22, wherein the contrast enhancement layer is a composite film that includes a plurality of first material layers and a plurality of second material layers stacked upon one another, and the corresponding relationship between the material of the contrast enhancement layer and the average grayscale value of the image of the contrast enhancement layer is a corresponding relationship between the average grayscale value of the image of the contrast enhancement layer and a layer number of the first material layers or the second material layers, and the physical analysis method further comprises:
determining, before the step of forming the contrast enhancement layer, a ratio of the layer number of the first material layers to the layer number of the second material layers according to the grayscale value database, so that the difference between the average grayscale value of the image of the contrast enhancement layer and the average grayscale value of the surface layer image of the sample to be inspected is at least 50.
