We report on development of digital circuits fabrication technique based on depletion mode AlGaN/GaN high electron mobility transistors (HEMTs) with adjusted threshold voltage. Transistors fabrication technique is based on fluorine plasma treatment of AlGaN/GaN on Sapphire HEMT gate region. Plasma treatment process based on CHF3/O2 gas mixture was developed. Post-treatment annealing process was applied...
A contact fabrication technology has been developed to achieve a low specific contact resistance to AlGaN/GaN heterostructures. The contact consisted of a Ti/Al/Ni/Au metal stack and was deposited by e-beam evaporation on semiconductor surface followed by rapid thermal annealing (RTA) in nitrogen. A specific contact resistance as low as 0.2 Ω∗mm at 870 °C. This low value was obtained by the optimization...
Definition the temperature dependence of electronic components parameters needs for their using in different devices. In this paper we research the temperature dependence of the parameters of test Schottky field-effect transistor based on gallium nitride (GaN) with nanostructure heterojunction. Our measuring platform is based on a two-channel measuring unit and Agilent Technologies E5273A probe-based...
For a number of years, IBRAE RAS has run the activities to form the bank of topographic and subject-matter electronic maps/plans of various scales. Principal tasks of the IBRAE Bank of Electronic Maps are formulated as follows: Development of a cartographic basis to support specialized GIS, information-reference systems, information-modeling and training systems developed at IBRAE; ...
