There's a lot of silicon circuitry running perfectly at liquid nitrogen temperature . Much more is run around -40 C . There's probably some at liquid helium temperature, but the cost of keeping things that cold usually means that circutry is outside the coldest zone . Colder is better, electrically . It's other environmental problems associated with cold which are the difficulty .

Before high temperature caused the silicon to become a "conductor", the aluminium wires connecting to the world would have melted . The various (essential: "doping") impurities would probably migrate over time at lesser temperatures .
