    摘要: In a method for use of x-ray diffraction to measure the strain on the top silicon germanium layer of an SOI substrate, the location of the peak diffraction area of an upper silicon layer of the SOI substrate is determined by first determining the peak diffraction area of the upper silicon layer on a reference pad (where the SOI thickness is about 700-900 Angstroms) within a die formed on a semiconductor wafer. The x-ray beam then moves to that location on the pad of interest to be measured and begins the XRD scan on the pad of interest to ultimately determine the strain of the top silicon germanium layer of the pad of interest

    摘要: A direct measurement of lattice spacing by X-ray diffraction is performed on a periodic array of unit structures provided on a substrate including semiconductor devices. Each unit structure includes a single crystalline strained material region and at least one stress-generating material region. For example, the single crystalline strained material region may be a structure simulating a channel of a field effect transistor, and the at least one stress-generating material region may be a single crystalline semiconductor region in epitaxial alignment with the single crystalline strained material region. The direct measurement can be performed in-situ at various processing states to provide in-line monitoring of the strain in field effect transistors in actual semiconductor devices.
