Для получения тонких пленок SiO2 методом БТО в качестве исходных образцов использовали пластины кремния КЭФ4,5 (100). Предварительно образцы окислялись при 1000 °С во влажном кислороде (толщина полученного SiO2 d = 100 нм), затем в растворе плавиковой кислоты проводилось полное снятие оксида кремния, после пластины подвергались химической очистке по технологии Radio Corporation of America (RCA). Окисление в стационарной атмосфере кислорода производилось в одну или две стадии при нагреве пластин импульсом света разной мощности до максимальных температур 1035 – 1250 °С, а также трехстадийным процессом, где заключительным этапом был отжиг в атмосфере азота либо в формовочном газе (N2 97 % + H2 3 %). Были проведены исследования характеристик азотированных в N2 барьерных структур SiO2-Si, полученных процессом БТО световыми потоками импульсами секундной длительности для улучшения электрофизических параметров оксидов затвора методом БТО, что представляет интерес для интегральных микросхем (ИС) с большой плотностью расположения активных областей приборов.</p></abstract><trans-abstract xml:lang="en"><p>Investigations of the thickness and optical characteristics of thin SiO2 films obtained by one-, two-, or three-stage rapid thermal processing (RTP) at atmospheric pressure, pulses of 6, 12, and 20 s duration have been carried out. To obtain thin SiO2 films by the RTP method, N-type:Ph 4.5 Оhm/□ (100) silicon wafers were used as initial samples. The samples were preliminarily oxidized at 1000 °C of the obtained wet oxygen (SiO2 d = 100 nm), then the silicon oxide was completely removed in a solution of hydrofluoric acid, after which the wafers were subjected to chemical cleaning using the Radio Corporation of America (RCA) technology. Oxidation in a stationary oxygen atmosphere was carried out in one or two stages by heating the plates with a light pulse of different power up to maximum temperatures of 1035 – 1250 °C, as well as a three-stage process, where the final stage was annealing in a nitrogen atmosphere or in a forming gas (N2 97% + H2 3%). The characteristics of SiO2-Si barrier structures nitrided in N2, obtained by the RTP process by light fluxes with pulses of a second duration, were studied to improve the electrophysical parameters of gate oxides by the RTP method. It is of interest for integrated circuits (ICS) with a high density of the active regions of devices.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>окисление кремния</kwd><kwd>толщина оксида кремния</kwd><kwd>фотодиссоциация</kwd><kwd>равномерность оксида кремния</kwd><kwd>прямое азотирование</kwd><kwd>показатель преломления</kwd><kwd>концентрация азота</kwd></kwd-group><kwd-group xml:lang="en"><kwd>silicon oxidation</kwd><kwd>silicon oxide thickness</kwd><kwd>photodissociation</kwd><kwd>silicon oxide uniformity</kwd><kwd>direct nitriding</kwd><kwd>refractive index</kwd><kwd>nitrogen concentration</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ahopelto J., Ardila G., Baldi, L.
