    摘要: A semiconducting device with a dual sidewall spacer and method of forming are provided. The method includes: depositing a first spacer layer over a patterned structure, the first spacer layer having a seam propagating through a thickness of the first spacer layer near an interface region of a surface of the substrate and a sidewall of the patterned structure, etching the first spacer layer to form a residual spacer at the interface region, where the residual spacer coats less than the entirety of the sidewall of the patterned structure, depositing a second spacer layer on the residual spacer and on the sidewall of the patterned structure not coated by the residual spacer, the second spacer layer being seam-free on the seam of the residual spacer, and etching the second spacer layer to form a second spacer coating the residual spacer and coating the sidewall of the patterned structure not coated by the residual spacer.

    摘要: A semiconducting device with a multilayer sidewall spacer and method of forming are described. In one embodiment, the method includes providing a substrate containing a patterned structure on a surface of the substrate and depositing a first spacer layer over the patterned structure at a first substrate temperature, where the first spacer layer contains a first material. The method further includes depositing a second spacer layer over the patterned substrate at a second substrate temperature that is different from the first substrate temperature, where the first and second materials contain the same chemical elements, and the depositing steps are performed in any order. The first and second spacer layers are then etched to form the multilayer sidewall spacer on the patterned structure.

    摘要: 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.

    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.
