Abstract:
A method for processing a substrate includes disposing the substrate in a deposition chamber configured to perform a deposition process and depositing a film on the substrate using the deposition process. The substrate having the film thereon is then transferred from the deposition chamber into a treatment chamber and a plasma cleaning process is performed on the substrate in the treatment chamber. Further processing of the substrate is performed after the plasma cleaning process.

Abstract:
A dielectric layer is created for use with non-volatile memory and/or other devices. The dielectric layer is created using atomic layer deposition to deposit multiple components whose mole fractions change as a function of depth in the dielectric layer in order to create a rounded bottom of a conduction band profile for the dielectric layer.
Abstract:
Methods of forming transistor devices and structures thereof are disclosed. A first dielectric material is formed over a workpiece, and a second dielectric material is formed over the first dielectric material. The workpiece is annealed, causing a portion of the second dielectric material to combine with the first dielectric material and form a third dielectric material. The second dielectric material is removed, and a gate material is formed over the third dielectric material. The gate material and the third dielectric material are patterned to form at least one transistor.
Abstract:
A process for the fabrication of a ferroelectric capacitor comprising depositing a layer of Ti (5) over an insulating layer (3) of AI 2 0 3 , and oxidising the Ti layer to form a Ti0 2 layer (7). Subsequently, a layer of PZT (9) is formed over the Ti0 2 layer (7). The PZT layer (9) is subjected to an annealing step in which, due to the presence of the Ti0 2 layer (7) it crystallises to form a layer (11) with a high degree of (111)-texture.
Abstract:
Ultra-thin oxide and oxynitride layers are formed utilizing low pressure processing to achieve self-limiting oxidation of substrates and provide ultra-thin oxide and oxynitride. 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 Si0 2 layers with a thickness of about 15Å, where the thickness of the Si0 2 layers varies less than about 1 Åover the substrates.
Abstract:
A first precursor gas is flowed to the substrate within the chamber effective to form a first monolayer on the substrate. A second precursor gas different in composition from the first precursor gas is flowed to the first monolayer within the chamber under surface microwave plasma conditions within the chamber effective to react with the first monolayer and form a second monolayer on the substrate which is different in composition from the first monolayer. The second monolayer includes components of the first monolayer and the second precursor. In one implementation, the first and second precursor flowings are successively repeated effective to form a mass of material on the substrate of the second monolayer composition. Additional and other implementations are contemplated.
