No they are not.
"The Bank of Russia has no plans to soften its stance on cryptocurrency regulation. Russia’s central bank has put together bills that prohibit the issuance, circulation, and possession of cryptocurrencies in Russia, with violations leading to fines, Vedomosti writes. According to the Governor of the Bank of Russia Elvira Nabiullina, the compromise option proposed by the Ministry of Finance - the concept of legalizing cryptocurrencies - does not stop their risks."
Actually a lot of Russian chips are manufactured by TSMC. In 28nm or 16nm process.
But the talk that these sanctions will impact the Russian military is bullshit. Russian military chips are manufactured in Russia.
At one time in late 1990s and early 2000s the Russian MIC used foreign sourced chips, including US chips, on export aircraft. For example in Indian Su-30MKI. But they were never used in Russian Federation bought aircraft.
Those other chips made by TSMC are used in government civilian servers, consumer TV set top boxes, and the like.
Other sanctions on those Russian companies, similar to the ones they threatened SMIC with though, could impact Russian military chip production. But I suspect these Russian companies could source a lot of those products, like materials and photoresist, from China and they could likely service the machines themselves by making their own parts. They are still using KrF.
Even if for whatever reason the production in Russia became impossible it should have no impact on current aircraft production plans for the next years. Given you have to order chips in lots of at least thousands of units and the Russians make like a couple dozen aircraft a year just do the math as to when they will exhaust their chip stockpile. They should have enough chips in stock. It is possible to respin and fab new chips in 18 months. These could easily be fabbed in China if Taiwan does not want to do it.
Russia has had plans to make their own 300mm 28nm fab for several years. It is a good thing they never bothered doing it.
The US could sanction their suppliers and grind production down making the investment useless. This way Russia can buy an all Chinese tools semi fab once the Chinese 28nm fab for Huawei becomes operational. They will just replicate it. The Russian Federation has always had great relations with Huawei. Huawei's first international expansion was to Russia. They are building the Russian 5G network. Huawei has hired thousands of telecoms engineers in Russia and they have huge R&D facilities there.
Russia also has high technical expertise and lots of engineering talent so they could easily improve on Chinese tools or even make their own. It is just that there are not enough economies of scale in Russian semi industry to justify that investment. But I could easily see Russia do counter sanctions on US if they hit their semi industry.
If the US cut Russia from semi fab materials, Russia is the world's largest producer of sapphire crystals. These are used by the US in military and space chips for rad hard applications. The US also uses silicon-on-sapphire to make GPS chips for military and civilian applications. Imagine Russia puts sanctions on sales of sapphire crystal exports to US based Peregrine Semiconductor for example.
The US would then be forced to import alternative, much more worse quality, smaller sapphire crystals from Japan.
