Downloading of the abstract is permitted for personal use only.Singe event effect (SEE) simulation in modern integrated circuits (ICs) by femtosecond laser irradiation through the substrate allows eliminating a lot of problems connected to the presence of multiple opaque metal layers above the IC active layer. With this irradiation geometry, the proper wavelength of laser radiation should be chosen to generate sufficient amount of nonequilibrium charge in the active layer on the one hand, and to avoid significant laser energy losses in the thick substrate on the other hand. In this paper several typical microelectronic ICs were selected to investigate the dependence of SEE generation effectiveness on the laser wavelength when irradiating through the substrate of various thickness. It was found, that the most appropriate laser wavelength for the silicon substrate thicknesses of 300 to 800 μm lies in the 1030 to 1070 nm range.
- ПубликацияТолько метаданныеInfluence of ultrashort laser drilling on magnetic and transport characteristics of HTS tapes(2019) Pokrovskii, S, V.; Mavritskii, O. B.; Egorov, A. N.; Mineev, N. A.; Timofeev, A. A.; Rudnev, I. A.; Покровский, Сергей Владимирович; Маврицкий, Олег Борисович; Егоров, Андрей Николаевич; Тимофеев, Алексей Афанасьевич; Руднев, Игорь АнатольевичWe investigated the magnetic and transport characteristics of second generation high-temperature superconducting (HTS) tapes with an ordered array of antidots. We have performed modification of HTS GdBa2Cu3O7-delta industrial tape produced by SuperOx (Russia) using femtosecond laser exposure. We have created a local lattice of defects with the period 50 mu m and the size of every hole up to 1 mu m. We studied the dependence of the critical current on magnetic field and the angular dependence of the critical current. The influence of the array of artificial defects on the pinning force was shown in a wide range of magnetic fields. Transport and magnetization measurements reveal that these modifications of HTS tapes increases the trapped magnetic field and the critical current. The local increase in the critical current reaches 49%. These enhancements of the critical current have been observed in the intermediate angles. The proposed method of antidot arrays by laser drilling can be used for local modification of HTS tapes, and can improve the current-carrying characteristics of industrial tapes.
- ПубликацияТолько метаданныеApplication of two-photon absorption technique for single-event effects simulation in silicon microelectronic devices(2022) Egorov, A. N.; Mavritskii, O. B.; Pechenkin, A. A.; Savchenkov, D. V.; Kholina, M. S.; Егоров, Андрей Николаевич; Маврицкий, Олег Борисович; Печенкин, Александр Александрович; Холина, Марта Сергеевна© 2022 SPIE.The application of two-photon absorption (TPA) for local nonequilibrium charge generation in the semiconductor microelectronic structures improves the 3D-spatial resolution of optical testing techniques (such as OBIC and similar), as compared to those, based on single-photon absorption (SPA). In this paper we discuss the results of laser single-event effect (SEE) simulation in digital potentiometer AD8400, using the TPA of tightly focused femtosecond laser radiation. The experiments were performed at the setup, which includes the tunable optical parametric amplifier with output wavelength in 900…1200 nm region. The results were compared to those obtained by SPA technique on the same experimental setup.
- ПубликацияТолько метаданныеPulsed Laser Single-Event Effect Simulation in AD8400 using Two-Photon Absorption(2022) Egorov, A. N.; Mavritskii, O. B.; Pechenkin, A. A.; Savchenkov, D. V.; Kholina, M. S.; Егоров, Андрей Николаевич; Маврицкий, Олег Борисович; Печенкин, Александр Александрович; Холина, Марта Сергеевна© 2022 IEEE.The results of laser single-event effect (SEE) simulation in digital potentiometer AD8400, using the two-photon absorption (TPA) of tightly focused femtosecond 1200 nm laser radiation are presented. Comparative measurements obtained by the single-photon absorption (SPA) of picosecond 1064 nm laser radiation in the same device revealed the improved 3D-spatial resolution of TPA compared to SPA-based pulsed laser testing. The effective depth of single event latchup (SEL) sensitive layer estimation was calculated from experimental results.
