    Abstract: Methods of fabricating an isolation structure on a substrate are provided. In one aspect, a method of fabricating an isolation structure on a substrate is provided that includes forming a first insulating layer on the substrate wherein the first insulating layer has a first sidewall. A trench is formed in the substrate that has a second sidewall. A second insulating layer is formed in the trench. The second insulating layer displaces the second sidewall laterally. The first insulating layer is densified by heating to liberate gas therefrom and thereby move the first sidewall into substantial vertical alignment with the second sidewall. The risk of substrate attack due to trench isolation structure pullback is reduced. Trench edges are covered by thick isolation material.

    Abstract: A fabrication process for semiconductor devices is disclosed for forming ultra-thin gate oxides, whereby a silicon substrate is subjected to an N2O plasma to form the ultra-thin gate oxide. According to one embodiment, the silicon substrate is heated in a deposition chamber and the N2O plasma is created by applying RF power to a showerhead from which the N2O is dispensed. By reacting an N2O plasma directly with the silicon substrate it is possible to achieve gate oxides with thicknesses less than 20 Å and relative uniformities of less than 1% standard deviation. The oxide growth rate resulting from the presently disclosed N2O plasma treatment is much slower than other known oxide formation techniques. One advantage of the disclosed N2O plasma treatment over thermal oxidation lies in the predictability of oxide growth thickness resulting from reaction with N2O plasma versus the strong variation in oxide formation rates exhibited by thermal oxidation. Following gate oxide formation, a high temperature anneal may be performed, preferably in an RTA apparatus. By combining the N2O plasma treatment with an RTA process, the disclosed method is believed to offer a controllable and reproducible method for fabricating highly uniform, ultra-thin gate oxides, having low trapping state densities.

    Abstract: A method is provided for forming high quality nitride sidewall spacers laterally adjacent to the opposed sidewall surfaces of a gate conductor dielectrically spaced above a semiconductor substrate. In an embodiment, a polysilicon gate conductor is provided which is arranged between a pair of opposed sidewall surfaces upon a gate dielectric. The gate dielectric is arranged upon a semiconductor substrate. Nitride is deposited from a high density plasma source across exposed surfaces of the substrate and the gate conductor. The high density plasma source may be generated within an ECR or ICP reactor containing a gas bearing N2 and SiH4. The energy and flux of electrons, ions, and radicals within the plasma are strictly controlled by the magnetic field such that a substantially stoichiometric and contaminant-free nitride is deposited upon the semiconductor topography. Thereafter, the nitride is anisotropically etched so as to form nitride spacers laterally adjacent the sidewall surfaces of the gate conductor.
