    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.
