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.

摘要： A method for producing thin, below 6 nm of equivalent oxide thickness, germanium oxynitride layer on Ge-based materials for use as gate dielectric is disclosed. The method involves a two step process. First, nitrogen is incorporated in a surface layer of the Ge-based material. Second, the nitrogen incorporation is followed by an oxidation step. The method yields excellent thickness control of high quality gate dielectrics for Ge-based field effect devices, such as MOS transistors. Structures of devices having the thin germanium oxynitride gate dielectric and processors made with such devices are disclosed, as well.

摘要： A structure, and method of fabrication, for high performance semiconductor field effect devices is disclosed. These devices are having a gate dielectric containing a germanate material. In representative embodiments the gate dielectric is essentially a layer of a germanate material. The chemical composition of such materials is MezGexOy, where Me stands for a metal with high ion polarizability, and x, y, and z are non-zero integers. Such a gate dielectric is advantageous, from the point of view of dielectric constant, barrier height, carrier mobility, thermal stability, and interface stability.

摘要： A method for forming an ultra thin gate dielectric for an integrated circuit device is disclosed. In an exemplary embodiment of the invention, the method includes forming an initial nitride layer upon a substrate by rapidly heating the substrate in the presence of an ammonia (NH3) gas, and then re-oxidizing the initial nitride layer by rapidly heating the initial nitride layer in the presence of a nitric oxide (NO) gas, thereby forming an oxynitride layer. The oxynitride layer has a nitrogen concentration therein of at about 1.0×1015 atoms/cm2 to about 6.0×1015 atoms/cm2, and has a thickness which may be controlled within a sub 10 Å range.
