摘要： The present invention generally provides a method for preparing an oxynitride film on a substrate. A surface of the substrate is exposed to oxygen radicals formed by ultraviolet (UV) radiation induced dissociation of a first process gas comprising at least one molecular composition comprising oxygen to form an oxide film on the surface. The oxide film is exposed to nitrogen radicals formed by plasma induced dissociation of a second process gas comprising at least one molecular composition comprising nitrogen using plasma based on microwave irradiation via a plane antenna member having a plurality of slits to nitridate the oxide film and form the oxynitride film.

摘要： A method is provided for forming a microstructure with an interfacial oxide layer by using a diffusion filter layer to control the oxidation properties of a substrate associated with formation of a high-k layer into the microstructure. The diffusion filter layer controls the oxidation of the surface. The interfacial oxide layer can be formed during an oxidation process that is carried out following deposition of a high-k layer onto the diffusion filter layer, or during deposition of a high-k layer onto the diffusion filter layer.

摘要： Ultra-thin oxide layers are formed utilizing low pressure processing to achieve self-limiting oxidation of substrates and provide ultra-thin oxide. The substrates to be processed can contain an initial dielectric layer such as an oxide layer, an oxynitride layer, a nitride layer, a high-k layer, or alternatively can lack an initial dielectric layer. The processing can be carried out using a batch type process chamber or, alternatively, using a single-wafer process chamber. One embodiment of the invention provides self-limiting oxidation of Si-substrates that results in SiO2 layers with a thickness of about 15 A, where the thickness of the SiO2 layers varies less than about 1 A over the substrates.
