Latest Patents

Abrosimov's latest patents highlight his expertise and creativity in semiconductor technology. One notable invention is a method and apparatus for producing single crystals composed of semiconductor material. This invention outlines a technique for generating a single crystal with properties akin to those of zone-pulled single crystals. The method involves using a vessel that is transmissive to high-frequency magnetic fields, along with a granulate of granular semiconductor material. By supplying high-frequency current to a specially designed planar inductor, an open melt lake is created, facilitating the upward pulling of a single crystal from the melt lake, ensuring it remains embedded and isolated from the wall of the vessel.

Another patent focuses on the production of monocrystalline silicon wafers with an approximately polygonal cross-section. This method describes a process in which a crystal is pulled vertically downwards from a rotating hanging melt drop. The approach emphasizes controlling the rotational speed during the crystal-growth phase, enabling the formation of silicon single crystal ingots tailored to specific geometrical requirements, ultimately leading to the production of wafers with precise characteristics.
