Abstract: Multicast transmissions do not allow for individual receivers to acknowledge that data was received by each receiver in the network. This is not acceptable for isochronous systems that require specific levels of QoS for each device. A multimedia communications protocol supports using multicast transmissions (one-to-many) in multimedia isochronous systems. A transmitter establishes a Multi-ACKed Multicast protocol within which a group of receiving devices can acknowledge the multicast transmission during a multi-acknowledgment period.

Abstract: Upstream burst transmit times are dynamically communicated to the transmit unit in grants issued over time and in any order. A critical parameter is when to trigger the operation to order the buffered data stream for transmission. If the ordering operation is triggered too soon, a later grant of an earlier burst transmit time may not be accounted for and the subsequent transmission could violate the transmission order rule. If the ordering operation is triggered too late, the decision to transmit a burst at an earlier burst transmit time may violate the margin rule. To address these concerns, a fetch offset time in advance of each granted burst transmit time is assigned. As each fetch offset time is sequentially reached, a next partial data portion of the buffered data stream is prepared for burst communication.

Abstract: An electronic device includes a ranging light source and a reflected light detector. A logic circuit causes the ranging light source to emit ranging light at a target. Reflected light from the target is detected using the reflected light detector, with the reflected light being a portion of the ranging light that reflects from the target back toward the reflected light detector. An intensity of the reflected light is determined using the reflected light detector. A distance to the target is determined based upon time elapsed between activating the ranging light source and detecting the reflected ranging light. Reflectance of the target is calculated, based upon the intensity of the reflected light and the distance to the target.

Abstract: A fin of silicon-germanium material is formed and covered with an epitaxially grown layer of silicon material. A dummy transistor gate is then formed to extend over a channel of the fin. Sidewall spacers are formed on each side of the dummy transistor gate and directly on top of the expitaxial silicon layer. Epitaxially grown raised source and drain regions are formed on each side of the dummy transistor gate adjacent the sidewall spacers. The dummy transistor gate and a portion of the epitaxial silicon layer (underneath said dummy transistor gate) are removed and replaced by a metal gate.

Abstract: A strip of sacrificial semiconductor material is formed on top of a non-sacrificial semiconductor material substrate layer. A conformal layer of the non-sacrificial semiconductor material is epitaxially grown to cover the substrate layer and the strip of sacrificial semiconductor material. An etch is performed to selectively remove the strip of sacrificial semiconductor material and leave a hollow channel surrounded by the conformal layer and the substrate layer. Using an anneal, the conformal layer and the substrate layer are reflowed to produce an optical waveguide structure including the hollow channel.

Abstract: Methods and structures for forming strained-channel finFETs are described. Fin structures for finFETs may be formed using two epitaxial layers of different lattice constants that are grown over a bulk substrate. A first thin, strained, epitaxial layer may be cut to form strain-relieved base structures for fins. The base structures may be constrained in a strained-relieved state. Fin structures may be epitaxially grown in a second layer over the base structures. The constrained base structures can cause higher amounts of strain to form in the epitaxially-grown fins than would occur for non-constrained base structures.

Abstract: A modified silicon substrate having a substantially defect-free strain relaxed buffer layer of SiGe is suitable for use as a foundation on which to construct a high performance CMOS FinFET device. The substantially defect-free SiGe strain-relaxed buffer layer can be formed by making cuts in, or segmenting, a strained epitaxial film, causing edges of the film segments to experience an elastic strain relaxation. When the segments are small enough, the overall film is relaxed so that the film is substantially without dislocation defects. Once the substantially defect-free strain-relaxed buffer layer is formed, strained channel layers can be grown epitaxially from the relaxed SRB layer. The strained channel layers are then patterned to create fins for a FinFET device. In one embodiment, dual strained channel layers are formed—a tensilely strained layer for NFET devices, and a compressively strained layer for PFET devices.

Abstract: A semiconductor device includes a plurality of gates formed upon a semiconductor substrate that includes a plurality of outer active areas (e.g. CMOS/PMOS areas, source/drain regions, etc.) and one or more inner active areas. An isolator is formed upon one or more inner gates associated with the one or more inner active areas. A contact bar electrically connects the outer active areas and/or outer gates and is formed upon the isolator. The isolator electrically insulates the contact bar from the one or more inner active areas and/or the one or more inner gates.

Abstract: A method is for making a semiconductor device. The method may include providing a lead frame having a recess, forming a sacrificial material in the recess of the lead frame, and mounting an IC on the lead frame. The method may include encapsulating the IC and the lead frame, removing portions of the lead frame to define lead frame contacts for the IC, and removing the sacrificial material to define for each lead frame contact a solder anchoring tab extending outwardly at a lower region and defining a sidewall recess between opposing portions of the solder anchoring tab and the encapsulation material.
