    摘要: A method of low-temperature oxidation of a silicon substrate includes placing a silicon wafer in a vacuum chamber; maintaining the silicon wafer at a temperature of between about room temperature and 350° C.; introducing an oxidation gas in the vacuum chamber including introducing an oxidation gas taken from the group of oxidation gases consisting of O2 and O3; dissociating the oxidation gas into radical oxygen with a xenon laser generating light at a wavelength of about 172 nm and flowing the radical oxygen over the silicon wafer; and forming an oxide layer on at least a portion of the silicon wafer.

    摘要: A method for annealing a high dielectric constant (high-k) gate dielectric layer includes placing a wafer including one or more partially formed transistors in an ambient. The ambient may include hydrogen and an oxidizing gas or the ambient may include nitrous oxide. Each transistor includes a high-k gate dielectric layer coupled to a substrate. The method further includes heating the high-k gate dielectric layer to a temperature greater than 650° C. while the gate dielectric layer is in the ambient. The ambient prevents or reduces the formation of lower dielectric constant (lower-k) material between the high-k gate dielectric layer and the substrate. Another method for annealing a high-k gate dielectric layer includes the use of an ambient including chemically active oxygen gas. When such an ambient is used, the high-k gate dielectric layer is heated to a temperature not greater than 600° C. while the gate dielectric layer is in the ambient.

    摘要: A method of forming a capacitor of a semiconductor device which can prevent disconnection between lower electrodes by blanket-depositing a second conductive film for silicidation on a semiconductor substrate and forming an oxide of the second conductive film such as titanium dioxide (TiO2) on an interlayer dielectric using high temperature oxidation, before depositing a dielectric film, and which can obtain a high capacitance by forming both a silicide layer including the second conductive film, and the oxide of the second conductive film such as titanium dioxide (TiO2) having a high dielectric constant, on a lower electrode, and using the silicide layer and oxide as the dielectric film.

    摘要: A method for making an electronic device, such as a MOS transistor, including the steps of forming a plurality of semiconductor islands on an electrically functional substrate, printing a first dielectric layer on or over a first subset of the semiconductor islands and optionally a second dielectric layer on or over a second subset of the semiconductor islands, and annealing. The first dielectric layer contains a first dopant, and the (optional) second dielectric layer contains a second dopant different from the first dopant. The dielectric layer(s), semiconductor islands and substrate are annealed sufficiently to diffuse the first dopant into the first subset of semiconductor islands and, when present, the second dopant into the second subset of semiconductor islands.
