Rostec created silicon from Russian materials

Ruselectronics holding of Rostec State Corporation presented a sample at the Innoprom-2022 exhibition

monocrystalline silicon createdentirely from Russian materials, according to the corporation's website. The technology will allow import substitution of foreign raw materials in the production of electronic power devices. The material is created in several stages. First, monosilane is synthesized from metallurgical silicon powder or from silicon dioxide, from which, in turn, polycrystalline silicon is obtained. It is on the basis of this semi-finished product that single-crystal silicon is created.

“Rostec has mastered the technology of its ownproduction of single-crystal silicon from Russian materials with a specific electrical resistance of more than 1000 ohm-cm. Thanks to this, it is possible to completely replace the imports of foreign raw materials that were used to produce silicon wafers for electronic power devices, such as transistors, thermistors, power rectifiers,” said Alexander Bushuev, CEO of Salyut Research and Production Enterprise, which developed the new technology.
