Gate security feature
An anti-counterfeiting security circuit is incorporated into an authentic integrated circuit device to induce failure in a counterfeited integrated circuit device by forming the security circuit (e.g., 21, 31, 41, 51) with one or more operatively inert high-k metal gate transistors (e.g., hkmg pmos 112) having switched or altered work function metal layers (82) where the security circuit defines a first electrical function with the one or more operatively inert high-k metal gate transistors and defines a second different electrical function if the one or more operatively inert high-k metal gate transistors were instead fabricated as operatively functional high-k metal gate transistors of the first polarity type with a work function metal layer of the first polarity type, the security circuit would define a second different electrical function.. .
