Vapour Phase Epitaxy as the Key Technology for Power MIS -transistors Based on Silicon Carbide Paper reports on features of SiC epitaxial growth in 4H–SiC vertical power MOSFET fabrication technology: for the drift layer formation and electrical properties optimization of the transistor channel. SiC components of power electronics have several advantages in comparison with traditional silicon ones. These components are characterized by higher electrical breakdown voltage, low active area resistance, high operating frequency, low losses at switching, high values of peak operating temperature and switching power density. Technologies of volume and epitaxial growth are the elements which enabled to create an electronic component basis for the 4H–SiC-based power electronics. Improvement of the epitaxial growth technology and quality of substrates permit to prepare instrument structures that demonstrate an advantage of SiC as the material of power electronics compared to other semiconductors.

Biomolecular computer: current state and trends of development Existing silicone computer technologies are coming to theoretical limit of scaling. The new breakthrough technologies with the help of which it will be possible to overcome these limits of scaling in the devices of information processing are required. One of the alternative approaches is to apply biomolecular chemical reactions for computation. Implementations of such computation based on DNA, proteins and molecular systems are reviewed.

Dynamic diffusion in binary composites measured by nuclear magnetic resonance Self-diffusion of water molecules measured with nuclear magnetic resonance (NMR) explores composite soft matter non-invasively. Detecting structural properties from NMR data is a challenging inverse problem and has to account for variability in shapes, sizes and concentrations of the compartments of soft matter. In this paper we develop a numerical method, providing a fundamental understanding of contrast diffusion mechanism in NMR signal closely linked to both the compartment hierarchy and the temporal spectrum. We model a composite with self-similar random structure and demonstrate that we retrieve the effective dynamic diffusion spectrum as function of geometries of different shapes, sizes and concentrations of disordered compartments of material.

Fast-scanning probe microscopy Fast-scanning probe microscopy makes it possible to study living objects at the molecular level with a millisecond time resolution, which provides new opportunities for biomedicine and personalized medicine in principle. The most interesting field of high-speed probe microscopy is solving the following complex tasks: determining bacterial antibiotic resistance, screening drugs using a single cell, targeted delivery of substances to a local area of biological tissue and a biological object, and early detection of biological agents.

The analysis of structural properties and parameters of objectsusing an integrated approach to processing x-ray optical measurement Investigations of thin-film microelectronic structures of low-k dielectrics and TiN diffusivebarrier layers using proposed complex of X-ray methods, particularly, reflectometry and diffused scattering have been accomplished. The advantages of this approach are that it allows of resolving ambiguities, such as "density-roughness" appeared at solving of inverse X-ray problems, identifying features of the studied structures formation and developing an analytical complex combined by self-consistent processing of the data obtained by several measurement methods in practice. In future, it is planned to adapt it to X-ray spectral and X-ray diffraction analysis methods to study the elemental and phase composition of objects, including the analysis of ore minerals.

Automated defect detection system in MEMS manufacturing Well-established systems of control and inspection of products at various technological stages play a key role in ensuring production flexibility, in continuous improvement of production processes and reduction of production losses. In MEMS production, an automated optical inspection is often used for these purposes, the result of which is a large number of images that require processing and analysis. This article presents the results of the implementation of the automated system for detecting defects of lithography, based on software for image processing, developed specifically for this purpose by AKSALIT Soft, at MAPPER.
