Electrical characterization and reliability of submicron SOI CMOS technology in the extended temperature range (to 300 °C)
I-V characteristics and reliability parameters for the set of hardened SOIMOSFET'swith special layouts and tungsten metallization to provide additional thermal tolerance for high-temperature SOI CMOS IC's are investigated in the temperature range up to 300 °C. The reliability aspects under test for MOSFET's are threshold voltage shift, subthreshold slope and mobility degradation, gate leakage current rise; for tungsten metallization (contacts, conductor lines and vias) I-T and R-T characteristics, failure time. The SOI MOSFET standard compact SPICE model BSIMSOI with traditional temperature limit of 150 °C ismodified to be used for CMOS IC simulation in the extended temperature range up to 300 °C. The results indicate that the 0.5–0.18 μm SOI MOSFET's with tungsten metallization have stable electrical behavior that makes them possible to be used during implementation of HT CMOS IC's (to 300 °C).
The considered model of the failure rate of CMOS VHSIC design proposed in the article Piskun G.A., Alekseev V.F., "Improvement of mathematical models calculating of CMOS VLSIC taking into account features of impact of electrostatic discharge", published in the first issue of the journal "Technologies of electromagnetic compatibility" for the year 2016. It is shown that the authors claim that this model "...will more accurately assess the reliability of CMOS VHSIC design" is fundamentally flawed and its application will inevitably lead to inadequate results. Alternatively, the proposed model of the failure rate of CMOS VHSIC design, which also allows to take into account the views of ESD, but based on the use of resistance characteristics of CMOS VHSIC to the effects of ESD.

The monograph contents totaled the many years results of Scientific school «The Automated System for Ensuring of Reliability and Quality of Equipment - ASONIKA» National research University «Higher school of Economics» (scientific supervisor of the Scientific school - academician of RANS, doctor of technical sciences, professor YU. Kofanov) and long-term cooperation with the scientists of Kiev Institute of mathematical machines and systems problems of the Ukrainian National Sciences Academy (Deputy Director on science, doctor of technical sciences V.P. Strelnikov). The final structure of the monograph had been formed in the discussion of modern problems of reliability aerospace electronic equipment at the XVII International scientific-technical conference «Systemic problems of reliability, quality, mathematical modelling, information and infocommunication technologies in innovation projects». This conference was dedicated to the 20th anniversary of the HSE. The book outlines the basics of probability-physical approach to the study and the assessment of the reliability of onboard aerospace equipment. Presents the methods of estimation of reliability parameters of electronic components, as according to reference data and test or operating results in the presence or absence of failures. Developed the methods of calculation of reliability parameters of mechanical elements of aerospace equipment as well as research methods reliability of redundant and non-redundant, non-renewable and renewable systems on the basis of adequate two-parameter distributions of diffusion. Established the theory of planning reliability test with lightweight, durable, including accelerated testing with new methods of processing the testing results and reliability assessment. We propose new methods of evaluation and prediction of the aerospace equipment reliability to measure the determining parameters. Developed methodology of the statistical characteristics evaluation of the degradation process for the study of single samples of aerospace equipment using information about its representative minobject (minibranch, mineralizatsiya). All problems of reliability, which is solved in this book (mathematical modeling, calculation and experimental evaluation of the reliability of systems) result in the identification of the time until failure (or to failure) distribution. It is proved that when assessing the reliability of onboard aerospace equipment, most accurate results diffusion DN-distribution. On the basis of the law of distribution can be carried out the evaluation of all the necessary parameters of aerospace equipment reliability (mathematical expectations developments, gamma-interest developments, the probability of non-failure operating time for the specified time, the residual resource and others). The book provides a large number of examples and problems, proving the effectiveness and efficiency of the proposed methods. Material monograph mostly taught HSE in the various courses of lectures. The monograph is intended for a wide circle of specialists working in the field design, testing and operation of onboard aerospace equipment, as well as students and graduate students of the HSE in the execution of their coursework, independent scientific research, and the preparation of graduation theses and dissertations.

The dynamics of a two-component Davydov-Scott (DS) soliton with a small mismatch of the initial location or velocity of the high-frequency (HF) component was investigated within the framework of the Zakharov-type system of two coupled equations for the HF and low-frequency (LF) fields. In this system, the HF field is described by the linear Schrödinger equation with the potential generated by the LF component varying in time and space. The LF component in this system is described by the Korteweg-de Vries equation with a term of quadratic influence of the HF field on the LF field. The frequency of the DS soliton`s component oscillation was found analytically using the balance equation. The perturbed DS soliton was shown to be stable. The analytical results were confirmed by numerical simulations.
