Russia doesnt rely on foreign semi-conductors for their military, they used to have France supply their T-90s with the Catherine thermal imagers, but from 2015 onwards its all domestically produced (product of early Western sanctions against Russia). You dont need a 7nm GA100 level of silicon in a Kalibr missile, 65nm* is enough for any modern military need.
*28nm is from TSMC, but they have the tech for it, but not for mass production, yet.
