    摘要: A method of making a high quality thin dielectric layer includes annealing a substrate and a base oxide layer overlying a top surface of the substrate at a first temperature in a first ambient and annealing the substrate and base oxide layer at a second temperature in a second ambient subsequent to the first anneal. The first ambient includes an inert gas ambient selected from the group consisting of a nitrogen, argon, and helium ambient. Prior to the first anneal, the base oxide layer has an initial thickness and an initial density. The first anneal causes a first density and thickness change in the base oxide layer from the initial thickness and density to a first thickness and density, with no incorporation of nitrogen, argon, or helium of the ambient within the base oxide layer. The first thickness is less than the initial thickness and the first density is greater than the initial density. The second anneal causes a second density and thickness change in the base oxide layer from the first thickness and density to a second thickness and density. The second thickness is larger than the first thickness and the second density is on the order of the greater than or equal to the first density.

    摘要: A high quality thin dielectric layer is achieved by annealing a substrate and base oxide layer at a first temperature in a first ambient and subsequently annealing the substrate and base oxide layer at a second temperature in a second ambient, the base oxide layer overlying a top surface of the substrate. Prior to the first anneal, the base oxide layer has an initial thickness and density. The first anneal causes a first density and thickness change in the base oxide layer from the initial thickness and density to a first thickness and density, with no incorporation of a component of the ambient within the base oxide layer. The first thickness is less than the initial thickness and the first density is greater than the initial density. The second anneal causes a second density and thickness change in the base oxide layer from the first thickness and density to a second thickness and density. The second thickness is larger than the first thickness and the second density is on the order of the greater than or equal to the first density.

    摘要: A method of forming a semiconductor device includes forming a high dielectric constant material over a semiconductor substrate, forming a conductive material over the high dielectric constant material, and performing an anneal in a non-oxidizing ambient using ultraviolet radiation to remove defects in the high dielectric constant material. Examples of a non-oxidizing ambient include for example nitrogen, deuterium, a deuterated forming gas (N2/D2), helium, argon or a combination of any two or more of these. Additional anneals using ultraviolet radiation may be performed. These additional anneals may occur in non-oxidizing or oxidizing ambients.
