    摘要: A semiconductor fabrication process includes forming a first etch mask (131) that defines a first opening (132) and a second etch mask (140) that defines a second opening (142) overlying an interlevel dielectric (ILD) (108). The ILD (108) is etched to form a first via (154) defined by the first opening (132) and a second via (152) defined by the second opening (142). The first etch mask (131) may include a patterned hard mask layer (122) and the second etch mask may be a patterned photoresist layer (140). The first etch mask may further include spacers (130) adjacent sidewalls of the patterned hard mask layer (122). The patterned hard mask layer (122) may be a titanium nitride and the spacers (130) may be silicon nitride. The ILD (108) may be an CVD low-k dielectric layer overlying a CVD low-k etch stop layer (ESL) (106).

    摘要: A non-planar semiconductor device (10) starts with a silicon fin (42). A source of germanium (e.g. 24, 26, 28, 30, 32) is provided to the fin (42). Some embodiments may use deposition to provide germanium; some embodiments may use ion implantation (30) to provide germanium; other methods may also be used to provide germanium. The fin (42) is then oxidized to form a silicon germanium channel region in the fin (36). In some embodiments, the entire fin (42) is transformed from silicon to silicon germanium. One or more fins (36) may be used to form a non-planar semiconductor device, such as, for example, a FINFET, MIGFET, Tri-gate transistor, or multi-gate transistor.

    摘要: A method and apparatus is presented that provides mobility enhancement in the channel region of a transistor. In one embodiment, a channel region (18) is formed over a substrate that is bi-axially stressed. Source (30) and drain (32) regions are formed over the substrate. The source and drain regions provide an additional uni-axial stress to the bi-axially stressed channel region. The uni-axial stress and the bi-axially stress are both compressive for P-channel transistors and tensile for N-channel transistors. Both transistor types can be included on the same integrated circuit.

    摘要: Two different transistors types are made on different crystal orientations in which both are formed on SOI. A substrate has an underlying semiconductor layer of one of the crystal orientations and an overlying layer of the other crystal orientation. The underlying layer has a portion exposed on which is epitaxially grown an oxygen-doped semiconductor layer that maintains the crystalline structure of the underlying semiconductor layer. A semiconductor layer is then epitaxially grown on the oxygen-doped semiconductor layer. An oxidation step at elevated temperatures causes the oxide-doped region to separate into oxide and semiconductor regions. The oxide region is then used as an insulation layer in an SOI structure and the overlying semiconductor layer that is left is of the same crystal orientation as the underlying semiconductor layer. Transistors of the different types are formed on the different resulting crystal orientations.

    摘要: Mechanical stress control may be achieved using materials having selected elastic moduli. These materials may be selectively formed by implantation, may be provided as a plurality of buried layers interposed between the substrate and the active area, and may be formed by replacing selected portions of one or more buried layers. Any one or more of these methods may be used in combination. Mechanical stress control may be useful in the channel region of a semiconductor device to maximize its performance. In addition, these same techniques and structures may be used for other purposes besides mechanical stress control.
