Main active elements in the frequency range from a few to a hundred gigahertz still are field-effect transistors with Schottky barrier based on gallium arsenide, other AB compounds and various heterostructures based on them. For optoelectronics, gall...
The lithographic methods are used to form contacts for nanostructures smaller than 100 nm , in part, e-beam lithography and focused ion beam lithography with the use of electron-sensitive resist. Focused ion beam lithography is characterized by great...
At the IC design phase it is required to consider all possible factors to ensure the produced device’s compliance with specified requirements. For instance, it is necessary to select an optimum package and to lower its impact on IC’s final characteri...
Transition from planar MOSFET structures to FinFET 3D structures ensures various radiation type resistance. However, the characteristics of radiation-exposed devices made at different factories vary considerably and it is hard to explain FinFET struc...
Intellectual Property (IP) cores are developed and used to accelerate the custom integrated circuits design flow and improve their final characteristics. There are two types of FPGA IP-cores: hard IP-core and soft IP-core. Hard IP-cores have an exact...
One of the main advantages of FPGA and CPLD is the high development speed; therefore, the importance of effective computer-aided design tools for modern microcircuits of these classes cannot be overestimated. Placement and routing are the most time-c...
In radioengineering systems, various methods and technical means are used for signal processing, the selection criteria of which are optimized for the best result of assigned task solution. The study of an analog signal shift on the time axis is one ...
Thermal methods of quality control of the plated-through hole (PTH) of printed circuit board (PCB) are based on thermal models. However, known thermal models of PTH take no account of heat transfer to PCB material thus not allowing for PTH heat chara...
The active state of carbon atoms is achieved in plasma at rigid energetic conditions. Proportion of particles with enough energy to activate carbon atoms is small. This work considers the result of energy input to carbon atom, which was in inert stat...
