The micro-feature includes a sidewall and the patterned substrate contains an isolation layer on the field area and on the sidewall and bottom of the micro-feature. The method includes forming a Si or SiGe seed layer at the bottom of the micro-feature, and at least partially filling the micro-feature from the bottom up by selectively growing Si or SiGe onto the Si or SiGe seed layer. According to one embodiment, the Si or SiGe seed layer is formed by depositing a conformal Si or SiGe layer onto the patterned substrate, removing the Si or SiGe layer from the field area, heat treating the Si or SiGe layer in the presence of H2 gas to transfer at least a portion of the Si or SiGe layer from the sidewall to the bottom of the micro-feature, and etching Si or SiGe residue from the field area and the sidewall.

摘要： A method is provided for in-situ formation of a thin oxidized AlN film on a substrate. The method includes providing the substrate in a process chamber, depositing an AlN film on the substrate, and post-treating the AlN film with exposure to a nitrogen and oxygen-containing gas. The post-treating increases the dielectric constant of the AlN film with substantially no increase in the AlN film thickness. The method can also include pre-treating the substrate prior to AlN deposition, post-annealing the AlN film before or after the post-treatment, or both.

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 extending time between chamber cleaning processes in a process chamber of a processing system. A particle-reducing film is formed on a chamber component in the process chamber to reduce particle formation in the process chamber during substrate processing, at least one substrate is introduced into the process chamber, a manufacturing process is performed in the process chamber, and the at least one substrate is removed from the process chamber. The particle-reducing film may be deposited on a clean chamber component or on a material deposit formed on a chamber component. Alternatively, the particle-reducing film may be formed by chemically modifying at least a portion of a material deposit on a chamber component. The particle-reducing film may be formed after each manufacturing process or at selected intervals after multiple manufacturing processes.

摘要： This invention provides a method for modifying the surface properties of a Si or Si alloy substrate by performing repeated etch-grow cycles of thermal oxide to yield a more defect free substrate with a more uniform nucleating surface which provides an improved interface for dielectric formation. Additionally, this method of processing does not expose the substrate to ambient atmosphere and preserves the improved surface until subsequent processing steps are performed.
