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.

The method includes providing a structure having an epitaxial Si surface and a patterned film, non-selectively depositing a carbon-doped Si film onto the structure, the carbon-doped Si film containing an epitaxial carbon-doped Si film deposited onto the epitaxial Si surface and a non-epitaxial carbon-doped Si film deposited onto the patterned film, and non-selectively depositing a Si film on the carbon-doped Si film, the Si film containing an epitaxial Si film deposited onto the epitaxial carbon-doped Si film and a non-epitaxial Si film deposited onto the non-epitaxial carbon-doped Si film. The method further includes dry etching away the non-epitaxial Si film, the non-epitaxial carbon-doped Si film, and less than the entire epitaxial Si film to form a strained epitaxial carbon-doped Si film on the epitaxial Si surface.

摘要： A method is provided for oxide removal from a substrate. The method includes providing the substrate in a process chamber where the substrate has an oxide layer formed thereon, and performing a sequential oxide removal process. The sequential oxide removal process includes exposing the substrate at a first substrate temperature to a flow of a first etching gas containing F2 to partially remove the oxide layer from the substrate, raising the temperature of the substrate from the first substrate temperature to a second substrate temperature, and exposing the substrate at the second temperature to a flow of a second etching gas containing H2 to further remove the oxide layer from the substrate. In one embodiment, a film may be formed on the substrate following the sequential oxide removal process.

摘要： A method for using a silicon germanium (SiGe) surface layer to integrate a high-k dielectric layer into a semiconductor device. The method forms a SiGe surface layer on a substrate and deposits a high-k dielectric layer on the SiGe surface layer. An oxide layer, located between the high-k dielectric layer and an unreacted portion of the SiGe surface layer, is formed during one or both of deposition of the high-k dielectric layer and an annealing process after deposition of the high-k dielectric layer. The method further includes forming an electrode layer on the high-k dielectric layer.
