    摘要: By forming MOSFETs on a substrate having pre-existing ridges of semiconductor material (i.e., a “corrugated substrate”), the resolution limitations associated with conventional semiconductor manufacturing processes can be overcome, and high-performance, low-power transistors can be reliably produced. Ridges on the corrugated substrate can be created using high precision techniques that are not ordinarily suitable for device production. MOSFETs that subsequently incorporate the high-precision ridges into their channel regions will typically exhibit much more precise and less variable performance than similar MOSFETs formed using optical lithography-based techniques that cannot provide the same degree of patterning accuracy. Additional performance enhancement techniques such as pulse-shaped doping, “wrapped” gates, epitaxially grown conductive regions, epitaxially grown high mobility semiconductor materials, high-permittivity ridge isolation material, and narrowed base regions can be used in conjunction with the segmented channel regions to further enhance device performance.

    摘要: A method of performing a timed etch of a material to a precise depth is provided. In this method, ion implantation of the material is performed before the timed etch. This ion implantation process substantially enhances the etch rate of the material within a precisely controlled depth range corresponding to the range of implantation-induced damage. By using the ion implantation, the variation in vertical etch depth can be reduced by a factor approximately equal to the etch rate of the damaged material divided by the etch rate of the undamaged material. The vertical etch depth can be used to provide a vertical dimension of a non-planar semiconductor device. Minimizing vertical device dimension variations on a wafer can reduce device and circuit performance variations, which is highly desirable.

    摘要: A multiple mask and a multiple masking layer technique can be used to pattern a single IC layer. A resolution enhancement technique can be used to define one or more fine-line patterns in a first masking layer, wherein each fine-line feature is sub-wavelength. Moreover, the pitch of each fine-line pattern is less than or equal to that wavelength. The portions of the fine-line features not needed to implement the circuit design are then removed or designated for removal using a mask. After patterning of the first masking layer, another mask can then be used to define coarse features in a second masking layer formed over the patterned first masking layer. At least one coarse feature is defined to connect two fine-line features, wherein the coarse feature(s) can be derived from a desired layout using a shrink/grow operation. The IC layer can be patterned using the composite mask formed by the patterned first and second masking layers.

    摘要: A multiple mask and a multiple masking layer technique can be used to pattern an IC layer. A RET can be used to define one or more fine-line patterns in a first masking layer. Portions of the fine-line features are then removed or designated for removal using a mask. This removal/designation can include accessing a desired layout (with at least one layout feature including a fine-line feature and a coarse feature) and expanding layout features only in directions along critical dimensions of those layout features. Another mask can then be used to define coarse features in a second masking layer formed over the patterned first masking layer. Coarse feature(s) can be derived from the desired layout using a shrink/grow operation performed only in directions orthogonal to a critical dimension of the fine-line features. The IC layer can be patterned using the composite mask formed by the patterned first and second masking layers.

    摘要: A non-volatile electro-mechanical diode memory cell is described for implementation of compact (4F2) cross-point memory arrays. The electro-mechanical diode memory cells operate with relatively low set/reset voltages and excellent retention characteristics, and are multi-time programmable. Due to its simplicity, this electro-mechanical diode memory cell is attractive for implementation of three-dimensional memory arrays for higher storage density.
