Abstract
Provided is an apparatus and method for measuring a thickness of thin film using x-ray where a thickness of a thin film of nanometer_(nm) level can be accurately measured without destructing an target sample, through determination of thickness of thin film of the target sample, by determining a calibration curve by comparing a difference of intensities of signals scattered by a special component included in a base layer of the reference sample.
