    Abstract: A method for making a semiconductor device may include forming, on a substrate, at least one stack of alternating first and second semiconductor layers. The first semiconductor layer may comprise a first semiconductor material and the second semiconductor layer may comprise a second semiconductor material. The first semiconductor material may be selectively etchable with respect to the second semiconductor material. The method may further include removing portions of the at least one stack and substrate to define exposed sidewalls thereof, forming respective spacers on the exposed sidewalls, etching recesses through the at least one stack and substrate to define a plurality of spaced apart pillars, selectively etching the first semiconductor material from the plurality of pillars leaving second semiconductor material structures supported at opposing ends by respective spacers, and forming at least one gate adjacent the second semiconductor material structures.

    Abstract: In an embodiment, a transmitter includes first and second transmission paths. The first transmission path is configurable to generate first pilot clusters each including a respective first pilot subsymbol in a first cluster position, and the second transmission path is configurable to generate second pilot clusters each including a respective second pilot subsymbol in a second cluster position such that a vector formed by the first pilot subsymbols is orthogonal to a vector formed by the second pilot subsymbols. For example, where such a transmitter transmits simultaneous orthogonal-frequency-division-multiplexed (OFDM) signals (e.g., MIMO-OFDM signals) over respective channels that may impart inter-carrier interference (ICI) to the signals due to Doppler spread, the pattern of the pilot symbols that compose the pilot clusters may allow a receiver of these signals to use a recursive algorithm, such as a Vector State Scalar Observation (VSSO) Kalman algorithm, to estimate the responses of these channels.

    Abstract: Methods and structures for forming a reduced resistance region of a finFET are described. According to some aspects, a dummy gate and first gate spacer may be formed above a fin comprising a first semiconductor composition. At least a portion of source and drain regions of the fin may be removed, and a second semiconductor composition may be formed in the source and drain regions in contact with the first semiconductor composition. A second gate spacer may be formed covering the first gate spacer. The methods may be used to form finFETs having reduced resistance at source and drain junctions.

    Abstract: Ultra-low-k dielectric materials used as inter-layer dielectrics in high-performance integrated circuits are prone to be structurally unstable. The Young's modulus of such materials is decreased, resulting in porosity, poor film strength, cracking, and voids. An alternative dual damascene interconnect structure incorporates deep air gaps into a high modulus dielectric material to maintain structural stability while reducing capacitance between adjacent nanowires. Incorporation of a deep air gap having k=1.0 compensates for the use of a higher modulus film having a dielectric constant greater than the typical ultra-low-k (ULK) dielectric value of about 2.2. The higher modulus film containing the deep air gap is used as an insulator and a means of reducing fringe capacitance between adjacent metal lines. The dielectric layer between two adjacent metal lines thus forms a ULK/high-modulus dielectric bi-layer.
