Patent ID: 8362794

Claim:
A method comprising: providing a plurality of field-effect-transistors (FETs) in a single integrated circuit (IC); operating said plurality of FETs under a first operation condition; reversing an operation direction for at least one of said plurality of FETs for a brief period of time; measuring a second operation condition of said one of said plurality of FETs during said brief period of time; and providing a reliability indicator of said plurality of FETs based upon a difference computed between said second operation condition and a reference operation condition, wherein said first operation condition is a forward saturated operation condition having a first operation current and a first operation voltage; said second operation condition is a reverse saturated operation condition having a second operation current and a second operation voltage; and said reference operation condition, having a reference operation current and a reference operation voltage, is said forward saturated operation condition at a time when said plurality of FETs starts regular usage.
