    摘要: A method of fabricating a memory cell including forming nanodots over a first dielectric layer and forming a second dielectric layer over the nanodots, where the second dielectric layer encases the nanodots. In addition, an intergate dielectric layer is formed over the second dielectric layer. To form sidewalls of the memory cell, a portion of the intergate dielectric layer and a portion of the second dielectric layer are removed with a dry etch, where the sidewalls include a location where a nanodot has been deposited. A spacing layer is formed over the sidewalls to cover the location where a nanodot has been deposited and the remaining portion of the second dielectric layer and the nanodots can be removed with an isotropic etch selective to the second dielectric layer.

    摘要: A pattern having exceptionally small features is printed on a partially fabricated integrated circuit during integrated circuit fabrication. The pattern is printed using an array of probes, each probe having: 1) a photocatalytic nanodot at its tip; and 2) an individually controlled light source. The surface of the partially fabricated integrated circuit comprises a photochemically active species. The active species undergoes a chemical change when contacted by the nanodot, when the nanodot is illuminated by light. To print a pattern, each probe raster-scans its associated nanodot across the surface of the partially fabricated integrated circuit. When the nanodot reaches a desired location, the nanodot is illuminated by the light source, catalyzing a change in the reactive species and, thus, printing at that location. Subsequently, reacted or unreacted species are selectively removed, thereby forming a mask pattern over the partially fabricated integrated circuit. The minimum size of the features in the pattern is determined by the size of the nanodot and can be very small, e.g., having critical dimensions of about 20 nm or less.

    摘要: The invention comprises methods of forming a conductive contact to a source/drain region of a field effect transistor, and methods of forming local interconnects. In one implementation, a method of forming a conductive contact to a source/drain region of a field effect transistor includes providing gate dielectric material intermediate a transistor gate and a channel region of a field effect transistor. At least some of the gate dielectric material extends to be received over at least one source/drain region of the field effect transistor. The gate dielectric material received over the one source/drain region is exposed to conditions effective to change it from being electrically insulative to being electrically conductive and in conductive contact with the one source/drain region. Other aspects and implementations are contemplated.

    摘要: A method of forming a thin film transistor relative to a substrate includes, a) providing a thin film transistor layer of polycrystalline material on a substrate, the polycrystalline material comprising grain boundaries; b) providing a fluorine containing layer adjacent the polycrystalline thin film layer; c) annealing the fluorine containing layer at a temperature and for a time period which in combination are effective to drive fluorine from the fluorine containing layer into the polycrystalline thin film layer and incorporate fluorine within the grain boundaries to passivate said grain boundaries; and d) providing a transistor gate operatively adjacent the thin film transistor layer. The thin film transistor can be fabricated to be bottom gated or top gated. A buffering layer can be provided intermediate the thin film transistor layer and the fluorine containing layer, with the buffering layer being transmissive of fluorine from the fluorine containing layer during the annealing. Preferably, the annealing temperature is both sufficiently high to drive fluorine from the fluorine containing layer into the polycrystalline thin film layer and incorporate fluorine within the grain boundaries to passivate said grain boundaries, but sufficiently low to prevent chemical reaction of the fluorine containing layer with the polycrystalline thin film layer.

The second hafnium-containing material is in a crystalline phase and/or orientation different from the crystalline phase and orientation of the hafnium-containing seed material. The second hafnium-containing material can be, for example, in an amorphous phase. The seed material is then utilized to induce a desired crystalline phase and orientation in the second hafnium-containing material. The invention also includes capacitor constructions utilizing hafnium-containing materials, and circuit assemblies comprising the capacitor constructions.
