  • Complementary field effect devices for eliminating or reducing diode effect
    Patent number: 6054722
    Abstract: A complementary device consisting of a PMOS TFT transistor and an NMOS FET transistor uses a conducting layer to shunt drain regions of the transistors to eliminate any detrimental diode or p-n junction effects. The use of the conducting layer significantly improves the current drive capabilities of the PMOS TFT when the complementary device is used to design SRAM cells with NMOS pull-down transistors.
