    摘要: A method and device providing a strained Si film with reduced defects is provided, where the strained Si film forms a fin vertically oriented on a surface of a non-conductive substrate. The strained Si film or fin may form a semiconductor channel having relatively small dimensions while also having few defects. The strained Si fin is formed by growing Si on the side of a relaxed SiGe block. A dielectric gate, such as, for example, an oxide, a high “k” material, or a combination of the two, may be formed on a surface of the strained Si film. Additionally, without substantially affecting the stress in the strained Si film, the relaxed SiGe block may be removed to allow a second gate oxide to be formed on the surface previously occupied by the relaxed SiGe block. Accordingly, a semiconductor device having a strained Si fin vertically oriented on a non-conductive substrate may be formed where the strained Si film is oriented such that it may form a channel of small dimensions allowing access to both sides and top in order to from single gate, double gate, or more gate MOSFETs and finFETs with a channel having a reduced number of defects and/or reduced dimensions.

    摘要: A part of the gate of a FINFET is replaced with a stress material to apply stress to the channel of the FINFET to enhance electron and hole mobility and improve performance. The FINFET has a SiGe/Si stacked gate, and before silicidation the SiGe part of the gate is selectively etched to form a gate gap that makes the gate thin enough to be fully silicidated. After silicidation, the gate-gap is filled with a stress nitride film to create stress in the channel and enhance the performance of the FINFET.
