Abstract:
An apparatus for observing a sample using an electron beam, comprising:an electron beam for irradiating on the sample; a sample stage on which the sample is placed; an x-ray detector for detecting x-rays generated from a micro sample taken from the sample as the electron beam irradiates the micro sample; a shielding piece comprised of carbon, beryllium, or an alloy of carbon and beryllium provided between the sample stage and the micro sample for reducing x-rays, wherein said shielding piece is incorporated into a portion of said sample stage, further wherein said micro sample is in contact with said shielding piece portion of the sample stage; and at least one additional shielding piece comprised of carbon, beryllium, or an alloy of carbon and beryllium incorporated into at least a second portion of said sample stage.
