摘要:
An in situ method for forming a HfO2 high-k dielectric layer in a batch wafer processing system. The method comprises first loading a plurality of wafers into a process chamber, and then pre-treating the plurality of wafers in the process chamber with a first oxidizer. After pre-treating the wafers, and without removing the wafers from the process chamber, the method then comprises depositing HfO2 on the plurality of wafers by atomic layer deposition, which comprises a plurality of deposition cycles, each cycle comprising alternating exposure of the plurality of wafers in the process chamber to a second oxidizer and a hafnium precursor. The hafnium precursor is selected from hafnium tert-butoxide (HTB) or hafnium tetra-diethylamide (TDEAH).

A method is provided for forming a metal-containing film on a substrate by a sequential gas exposure process in a batch type processing system. A metal-containing film can be formed on a substrate by providing a substrate in a process chamber of a batch type processing system, heating the substrate, sequentially flowing a pulse of a metal-containing precursor gas and a pulse of a reactant gas in the process chamber, and repeating the flowing processes until a metal-containing film with desired film properties is formed on the substrate. The method can form a metal-oxide film, for example HfO2 and ZrO2, a metal-oxynitride film, for example HfxOzNw, and HfxOzNw, a metal-silicate film, for example HfxSiyOz and ZrxSiyOz, and a nitrogen-containing metal-silicate film, for example HfxSiyOzNw and ZrxSiyOzNw. A processing tool containing a batch type processing system for forming a metal-containing film by a sequential gas exposure process is provided.

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.

A method is provided for reduced defect such as void free or reduced void Si or SiGe deposition in a micro-feature on a patterned substrate. 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.

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.

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.
