Пленки хрома толщиной порядка 30 нм наносили магнетронным распылением хромовой мишени ионами аргона на кремниевые подложки при комнатной температуре. Быструю термообработку проводили в интервале температур от 200 до 550 °С в режиме теплового баланса путем облучения обратной стороны подложек некогерентным световым потоком кварцевых галогенных ламп в среде азота в течение 7 с. Установлено, что формирование гексагональной фазы дисилицида хрома с размером зерен 150–300 нм происходит пороговым образом при превышении температуры быстрой термообработки 400 °С. Одновременно происходят сильные изменения поверхностной морфологии пленок, возникает шероховатость поверхности и границы раздела силицид-кремний. При этом волнообразная морфология поверхности пленки практически повторяет морфологию границы раздела силицида с кремнием (то есть является точной репликой границы раздела). Предложен и обсуждается механизм формирования шероховатости структуры границы раздела дисилицида хрома с кремнием, основанный на учете эффекта Киркендала и деформационно-стимулированной диффузии вакансий. Результаты исследований структуры и морфологии слоев дисилицида хрома на кремнии хорошо согласуются с результатами электрофизических измерений барьера Шоттки. Полученные результаты могут быть использованы в микроэлектронике при формировании выпрямляющих контактов и металлизации межсоединений в интегральных схемах, а также с целью термоэлектрических и оптоэлектронных применений.</p></abstract><trans-abstract xml:lang="en"><p>The formation of chromium disilicide layers on n-type single crystal silicon substrates (111) during rapid thermal annealing in heat balance mode by the methods of Rutherford backscattering, X-ray diffraction and transmission electron microscopy of cross sections was investigated. Chromium films of about 30 nm thickness were deposited by magnetron sputtering of a chromium target with argon ions onto silicon substrates at room temperature. The rapid thermal treatment was carried out in a temperature range of 200 to 550 °C in a heat balance mode by irradiating the substrates backside with a non-coherent light flux of quartz halogen lamps in a nitrogen ambient for 7 s. It was established that hexagonal phase of chromium disilicide formation with grain size of 150–300 nm occurs in a threshold manner when the temperature of rapid thermal treatment exceeds 400 °C. At the same time, there are strong changes in the films surface morphology and surface roughness, and a silicide-silicon interface occur. In this case the wavy film surface morphology practically repeats silicide-silicon interface morphology (the surface exactly replicates the interface). The mechanism of CrSi2/Si interface structure roughness formation based on consideration of Kirkendall effect and deformation-stimulated diffusion of vacancies is proposed and discussed. The research results of the structure and morphology of CrSi2 layers on silicon are well-correlated with the results of the Schottky barrier electrophysical measurements. The results obtained can be used in microelectronics for forming rectifying contacts and interconnects metallization for integrated circuits, as well as for thermoelectric and optoelectronic applications.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>быстрая термообработка</kwd><kwd>дисилицид хрома</kwd><kwd>структурно-фазовые превращения морфология поверхности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rapid thermal treatment</kwd><kwd>chromium disilicide</kwd><kwd>structure and phase transformations</kwd><kwd>surface morphology</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования проводились в рамках проектов ГПНИ (№ ГР 20190644, № ГР 20191100).
