ABSTRACT:
Gates of individual devices on a slice are connected through a resistance to the device substrate, and through the same resistance to other device gates. This interconnection and high-resistance drain gives the gate protection from static charge buildup and subsequent catastrophic discharge which would result in a faulty device. This method protects each gate from the time of deposition to final device packaging.
