摘要
A camouflaged application specific integrated circuit is disclosed. The camouflaged ASIC includes at least one camouflaged FinFET, which includes a substrate of a first conductivity type, a fin, disposed on the substrate, the fin including a source region of a second conductivity type, a drain region of the second conductivity type, and a channel region of the first conductivity type. The camouflaged application specific integrated circuit also includes a gate disposed over and substantially perpendicular to the channel region, forming one or more transistor junctions with the fin. In one embodiment, the substrate includes a punch through stop (PTS) region of the second conductivity type disposed between the fin and the substrate, the PTS region electrically shorting the source region of the fin to the drain region of the fin.
