Abstract
An X-ray apparatus includes a mount, an X-ray source, a detector, an optical gauge and a motor. The mount is configured to hold a planar sample having a first side, which is smooth, and a second side, which is opposite the first side and on which a pattern has been formed. The X-ray source is configured to direct a first beam of X-rays toward the first side of the sample. The detector is positioned on the second side of the sample so as to receive at least a part of the X-rays that have been transmitted through the sample and scattered from the pattern. The optical gauge is configured to direct a second beam of optical radiation toward the first side of the sample, to sense the optical radiation that is reflected from the first side of the sample, and to output a signal, in response to the sensed optical radiation, that is indicative of a position of the sample. The motor is configured to adjust an alignment between the detector and the sample in response to the signal.
