Получено, что увеличение времени диффузии иона в материале с пористостью 30 %, радиусом пор 1 нм (для входных параметров, указанных в статье) за счет увеличения диффузионного пути можно оценить в 16 %. При этом совместный учет эффекта увеличения электрического поля на краях пор и уменьшения энергии активации диффузии приводит к уменьшению времени до пробоя на 26 % относительно плотного материала.</p></abstract><trans-abstract xml:lang="en"><p>In this work, simulation modeling of processes of the diffusion of copper ions in low-k dielectric between two neighboring copper lines is performed. It was found that an increase in the diffusion time of an ion in a material with a porosity of 30% and a pore radius of 1 nm (for the input parameters specified in the work) due to an increase in the diffusion path can be estimated at 16%. Moreover, the combined consideration of the effect of an increase in the electric field at the edges of the pores and a decrease in the diffusion activation energy leads to a decrease in the time to breakdown by 26% relatively dense material.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>low-k диэлектрик</kwd><kwd>пористость</kwd><kwd>временной пробой диэлектрика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>low-k dielectric</kwd><kwd>porosity</kwd><kwd>TDDB</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">International technology roadmap for semiconductors (ITRSTM) interconnect. 2020 Edition. https://irds.ieee.org/editions/2020</mixed-citation><mixed-citation xml:lang="en">International technology roadmap for semiconductors (ITRSTM) interconnect. 2020 Edition. https://irds.ieee.org/editions/2020</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Maex K., Shamiryan D., Iacopi F., Brongersma S.H., Baklanov M.R., Yanovitskaya Z.S.
