Teacher from Altai State University has developed a unique device that will improve the production of modern microelectronics components
On December 12, 2023, the first defense took place in the recently opened dissertation council 24.2.269.03 (Physical and Mathematical Sciences) at Altai State University. The dissertation for the degree of Candidate of Physical and Mathematical Sciences in the specialty 1.3.2 Instruments and methods of experimental physics was defended by the teacher of the Department of General and Experimental Physics of the Institute of Digital, Electronics and Physics Technologies Alexander Katasonov on the topic “Eddy current method for studying inhomogeneities and defects of thin metal films”, scientific supervisor – Doctor of Physical and Mathematical Sciences Anatoly Sagalakov.
The dissertation work is devoted to the development of a software and hardware complex in which the eddy current method is implemented. The developed miniature eddy current sensor allows local scanning of thin conductive layers, measuring the size of defects and inhomogeneities with an area of \u200b\u200bfrom 104 μm2. Such miniature measuring systems are widely used in the production of modern microelectronics components.
“My development is aimed at studying thin films, which are an integral part of microelectronics production. This is all the stuffing of our modern phones and computers. My development will improve the efficiency of this production, the economic component, and reduce defects. Our method is non-contact and has higher productivity compared to the methods that are mainly used,” said Alexander Katasonov.
