Abstract
A method and apparatus for unambiguous, precise and self-calibrating detection of unreliable semiconductor operation is provided. The apparatus includes an optically coupled sensor positioned over a semiconductor device and an electrical feedback control loop for adjusting the operating range of the semiconductor device. The method includes the steps of measuring optical emissions from a semiconductor device and adjusting compensation circuitry connected to the semiconductor device in response to the measured emissions.
