    摘要: In order to control the position of a specimen on a specimen holder with high accuracy, a specimen cartridge (1) is made of a good thermal conductor, an outer frame (5) is made of heat insulating material and a connecting rod is made of a poor thermal conductor. The temperature distribution of the specimen (2) becomes uniform and the temperature drift is reduced. Further, thermal expansion of a specimen cartridge tilting rod (3) does not affect the tilting angle. These features make it possible to perform various highly accurate observations and measurements with an electron microscope.

    摘要: Provided is a thin film stack inspection method capable of accurately measuring and inspecting layer thicknesses of thin film stacks. An X-ray having a long coherence length is used as an incident X-ray and the X-ray specular-reflected from a sample placed on a goniometer is partially bent by a prism. The X-ray bent by the prism and the X-ray going straight are made to interfere with each other to obtain interference patterns. Though being thin film stacks, the sample has a portion having no thin film and thus an exposed substrate. The X-ray not bent by the prism includes an X-ray specular-reflected from the exposed substrate. By changing the incident angle from 0.01° to 1°, the interference patterns of the specular-reflected X-ray are measured. Thus, layer thicknesses are measured using a change in a phase of the X-ray reflected from a film stack interface.
