Abstract :
Modulation of reflected light intensity by electronic device operation is well established as a backside contactless probing technique. In this paper, we present a simple setup for mapping reflected light signals across semiconductor devices. In the experiment, metal-oxide-semiconductor field-effect transistors (MOSFET) were used in different operating conditions.
