90nm is probably too good for microcontrollers :-) STMicroelecronics make most of (cheaper) microcontrollers on 180nm, AVR's are closer to 500nm... There are lots of Russian microcontrollers already available (based on Cortex-M3, M0, M4 cores), but at the moment they are manufactured overseas (X-Fab is favorite fab in Russia). Domestically-manufactured microcontrollers are much simpler (AVR or old PIC-level, there is even Russian AVR clone, which is not very widely used).
