    Abstract: A finFET structure includes a semiconductor fin located over a substrate. A gate electrode is located traversing the semiconductor fin. The gate electrode has a spacer layer located adjoining a sidewall thereof. The spacer layer does not cover completely a sidewall of the semiconductor fin. The gate electrode and the spacer layer may be formed using a vapor deposition method that provides for selective deposition upon a sidewall of a mandrel layer but not upon an adjoining surface of the substrate, so that the spacer layer does not cover completely the sidewall of the semiconductor fin. Other microelectronic structures may be fabricated using the lateral growth methodology.

    Abstract: A well isolation trenches for a CMOS device and the method for forming the same. The CMOS device includes (a) a semiconductor substrate, (b) a P well and an N well in the semiconductor substrate, (c) a well isolation region sandwiched between and in direct physical contact with the P well and the N well. The P well comprises a first shallow trench isolation (STI) region, and the N well comprises a second STI region. A bottom surface of the well isolation region is at a lower level than bottom surfaces of the first and second STI regions. When going from top to bottom of the well isolation region, an area of a horizontal cross section of the well isolation region is an essentially continuous function.

    Abstract: An integrated circuit and method for fabrication includes first and second structures, each including a set of sub-lithographic lines, and contact landing segments connected to at least one of the sub-lithographic lines at an end portion. The first and second structures are nested such that the sub-lithographic lines are disposed in a parallel manner within a width, and the contact landing segments of the first structure are disposed on an opposite side of a length of the sub-lithographic lines relative to the contact landing segments of the second structure. The contact landing segments for the first and second structures are included within the width dimension, wherein the width includes a dimension four times a minimum feature size achievable by lithography.

    Abstract: A field effect transistor is formed having wrap-around, vertically-aligned, dual gate electrodes. Starting with a silicon-on-insulator (SOI) structure having a buried silicon island, a vertical reference edge is defined, by creating a cavity within the SOI structure, and used during two etch-back steps that can be reliably performed. The first etch-back removes a portion of an oxide layer for a first distance over which a gate conductor material is then applied. The second etch-back removes a portion of the gate conductor material for a second distance. The difference between the first and second distances defines the gate length of the eventual device. After stripping away the oxide layers, a vertical gate electrode is revealed that surrounds the buried silicon island on all four side surfaces.
