Empty-space-in-silicon technique for fabricating a silicon-on-nothing structure

Abstract: A promising technique to form the silicon-on-nothing structure is presented as an alternative to the silicon-on-insulator structure. A large plate-shaped empty space in silicon (ESS) below the surface of the silicon substrate can be fabricated by connecting the spherical empty spaces, which are formed by surface migration of Si on the patterned Si substrate. The ESS technique has the potential to change the microprocess for the fabrication of large-scale integrated circuits and it can be applied to various man… Show more

“…The produced Si scaffold obtained in this way retains the monocrystalline nature of the original substrate, what has deep implications on its thermal stability. The monocrystalline core will remain stable up to the melting temperature of silicon due to the lack of grain boundaries; however, microstructures are still sensitive to oxygen and surface diffusion effects [23,24], which soften them in solid phase. Hopefully, both effects can be effectively suppressed under the appropriate non-oxidizing atmospheres.…”

“…Several available methods for the transfer of perovskite films are the laser lift-off process, 2,3 ion cutting, 4 the use of water-soluble substrates, 5,6 and the epifree process. 7,8 In this letter, an approach for film transfer is demonstrated that makes use of seed layers of nanosheets on arbitrary sacrificial substrates. Nanosheets are essentially two-dimensional single crystals; they have a constant thickness of a few nanometers at most and their lateral size is mostly in the micrometer range, 9 while their oriented crystal structure enables them to direct epitaxial growth of thin films.…”

“…Оценки показывают, что для цилиндрической поры в кремнии диаметром 1.2 мкм при α = 6.24 · 10 14 эВ/см 2 [13] это давление составляет около 17 атмосфер. Цилиндрическая полость являет-ся неравновесной и стремится изменить свою форму, превратившись в сферу, или при высоком аспектном отношении глубины поры к ее диаметру разделиться на несколько изомерных сфер [22,26], что и наблюдалось в работах [8,9]. Перемещение атомов по поверхности изменяет форму поры, сохраняя неизменным ее объем.…”

“…Спекание макропор сопровождается распадом цилиндрических пустот на изомерные сферы и также образованием беспористой корки [8]. Если макропоры организованы в регуляр-ную решетку, то при спекании можно сформировать сплошную полость под слоем кремния и получить структуру Silicon On Nothing (SON) [9].…”
