Abstract: FIELD: crystal analysis. SUBSTANCE: method is related to X-ray diffraction analysis of crystals, in particular, of residual mechanical stresses and structural perfection of semiconductor plates-substrates, homo- and heterocompositions after various technological operations when manufacturing discrete devices and integrated microcircuits in solid-state microelectronics. Method includes forming two parallel monochromatic X-rays directed on to examined plate. Determination of difference of reflection angles of these rays from different points located at specified distance from each other on curved surface is performed by successive bringing them into reflecting position by turn of plate about rotational axis perpendicular to plane holding incident and reflected rays, and located in the middle between points of incidence of rays on to reflecting surface. Third central ray parallel to first two rays and arranged at equal distances from each of them is formed simultaneously with them and is directed on to examined surface. It is used to orient plate before measurement of curvature. Determination of difference of angles of rays reflection noncoinciding with central one is conducted before and after turns of plate through 180 deg about rotational axis lying in plane of ray passage and matching normal to surface at point of reflection of central ray. Curvature is found by formula $$$, where K is curvature of plate ($$$, R is radius of curvature); S is distance between rays on reflecting surface; $$$ and $$$ are correspondingly differences of reflection angles before and after turn of plate through 180 deg about normal to surface at point of reflection of central ray.
