They are also working on super heat resistant microprocessors. In the past, integrated circuit chips could not withstand more than a few hours of high temperatures before degrading or failing. This chip exceeded 1,700 hours of continuous operation at 500 degrees Celsius - a breakthrough that represents a 100-fold increase in what has previously been achieved. The new silicon carbide differential amplifier integrated circuit chip may provide benefits to anything requiring long-lasting electronic circuits in very hot environments.
