Abstract :
High-resolution X-ray diffraction has been carried out by using a vertically and horizontally condensed X-ray microbeam at the Hyogo beamline (BL24XU) of SPring-8. The microbeam is 7×5 μm2 in size and it possesses a small angular divergence and a narrow energy bandwidth. The sample is a Si substrate on which thermal oxide films are fabricated with fine patterns. At the region of the line-and-space pattern, many periodic peaks lying along the transverse direction are observed in a reciprocal space map. Those patterns are attributed to some local strain distribution due to the patterned oxide film on the Si wafer.
