This paper presents a comparative assessment of alternative grown and deposited gate dielectrics in sub-micron fabricated devices. High quality rapid-thermal CVD oxides and oxynitrides are examined as alternatives to conventional furnace grown gate oxides. An alternative gate process using in-situ boron doped and RTCVD deposited poly-Si is explored. PMOSFETs with Leff down to 0.06 μm were fabricated using a 0.1 μm technology. Electrical characterization of fabricated devices revealed excellent control of gate-boron depletion with the in-situ gate deposition process in all devices. Boron penetration of 2.0 nm gate oxides was effectively controlled by the use of a lower temperature RTA process. The direct tunneling leakage, although significant at these thicknesses, was less than 1 mA/cm2 at Vd = −1.2 V for all dielectrics. MOSFETs with comparable drive currents and excellent junction and off-state leakages were obtained with each dielectric.}, journal={RAPID THERMAL AND INTEGRATED PROCESSING VII}, author={Srivastava, A and Heinisch, HH and Vogel, E and Parker, C and Osburn, CM and Masnari, NA and Wortman, JJ and Hauser, JR}, year={1998}, pages={163–170} } @article{parker_lucovsky_hauser_1998, title={Ultrathin oxide-nitride gate dielectric MOSFET's}, volume={19}, ISSN={["0741-3106"]}, DOI={10.1109/55.663529}, abstractNote={The first ultrathin oxide-nitride (O-N) gate dielectrics with oxide equivalent thickness of less than 2 nm have been deposited and characterized in n-MOSFET's.
