Abstract: A tensile strained silicon layer is patterned to form a first group of fins in a first substrate area and a second group of fins in a second substrate area. The second group of fins is covered with a tensile strained material, and an anneal is performed to relax the tensile strained silicon semiconductor material in the second group of fins and produce relaxed silicon semiconductor fins in the second area. The first group of fins is covered with a mask, and silicon-germanium material is provided on the relaxed silicon semiconductor fins. Germanium from the silicon germanium material is then driven into the relaxed silicon semiconductor fins to produce compressive strained silicon-germanium semiconductor fins in the second substrate area (from which p-channel finFET devices are formed). The mask is removed to reveal tensile strained silicon semiconductor fins in the first substrate area (from which n-channel finFET devices are formed).

Abstract: Elongated fins of a first semiconductor material are insulated from and formed over an underlying substrate layer (of either SOI or bulk type). Elongated gates of a second semiconductor material are then formed to cross over the elongated fins at channel regions, and the gate side walls are covered by sidewall spacers. A protective material is provided to cover the underlying substrate layer and define sidewall spacers on side walls of the elongated fins between the elongated gates. The first semiconductor material and insulating material of the elongated fins located between the protective material sidewall spacers (but not under the elongated gates) is removed to form trenches aligned with the channel regions. Additional semiconductor material is then epitaxially grown inside each trench between the elongated gates to form source-drain regions adjacent the channel regions formed by the elongated fins of the first semiconductor material located under the elongated gates.

Abstract: In an embodiment, a transmitter includes a transmission path configurable to generate first pilot clusters in response to a matrix, each first pilot cluster including a respective first pilot subsymbol in a first cluster position and 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, the matrix having a dimension related to a number of cluster positions in each of the first pilot clusters. 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 estimate the responses of these channels more accurately than conventional receivers.

Abstract: A transistor device is fabricated by growing an epitaxial layer of semiconductor material on a semiconductor layer and forming an opening extending through the epitaxial layer at a position where a gate is to be located. This opening provides, from the epitaxial layer, a source epitaxial region on one side of the opening and a drain epitaxial region on an opposite side of the opening. The source epitaxial region and a first portion of the semiconductor layer underlying the source epitaxial region are then converted into a transistor source region. Additionally, the drain epitaxial region and a second portion of the semiconductor layer underlying the drain epitaxial region are converted into a transistor drain region. A third portion of the semiconductor layer between the transistor source and drain regions forms a transistor channel region. A transistor gate electrode is then formed in the opening above the transistor channel region.

The filler material in the recesses provides a wetable surface for filler material, such as solder, to adhere to during mounting of the package to another device, such as a printed circuit board (PCB). This enables strong solder joints between the leads of the package and the PCB. It also enables improved visual inspection of the solder joints after the package has been mounted.

The overlap region directly overlies the first interlayer dielectric adjacent to the interconnect, and the connection region directly contacts the interconnect. The first cap is positioned between the overlap region and the first interlayer dielectric.

A second sidewall peripherally surrounds each of the raised source region and raised drain region. The second sidewall extends above a top surface of the raised source region and raised drain region to define regions laterally delimited by the first and second sidewalls. A conductive material fills the regions to form a source contact and a drain contact to the raised source region and raised drain region, respectively.

Abstract: A modulated digital input signal is passed through a conditioning circuit to generate a first input signal. An error amplifier circuit receives the first input signal and a second input signal, and controls the operation of a MOS transistor to generate an output signal that is current modulated. The output signal is sensed to generate a feedback signal. A switching circuit selectively applies the feedback signal as the second input signal in response to a transition of the modulated digital input signal from a first logic state to a second logic state. The switching circuit alternatively selectively applies a fixed reference signal as the second input signal to the error amplifier in response to a transition of the modulated digital input signal from the second logic state to the first logic state.
