  • Patent number: 10354927
    Abstract: Integrated circuits are disclosed in which the strain properties of adjacent pFETs and nFETs are independently adjustable. The pFETs include compressive-strained SiGe on a silicon substrate, while the nFETs include tensile-strained silicon on a strain-relaxed SiGe substrate. Adjacent n-type and p-type FinFETs are separated by electrically insulating regions formed by a damascene process. During formation of the insulating regions, the SiGe substrate supporting the n-type devices is permitted to relax elastically, thereby limiting defect formation in the crystal lattice of the SiGe substrate.

  • Patent number: 10347569
    Abstract: Embodiments of the present disclosure are directed to leadframes having the cantilevered extension that includes an integral support on the end of the lead nearest the die pad. A support integral to the leadframe allows the support to be built to the proper height to support the cantilevered lead in each package and reduces or eliminates the upward, downward, and side to side deflections caused or allowed by supports built-in to the tooling of the manufacturing equipment. Also, by building the support into the leadframe, the leadframes may be pretaped prior to the die attach and wire bonding steps of the manufacturing process.

  • Publication number: 20190208240
    Abstract: A channel stream is received and demultiplexed into a video packetized elementary stream (PES), audio packetized elementary stream (PES), and program clock reference (PCR). Indexing circuitry stores the video PES and the audio PES in a buffer, locates a presentation time stamp (PTS) in the video PES and stores that PTS in the buffer, locates a start of each group of pictures (GOP) in the video PES and stores those locations in the buffer, and locates a PTS in the audio PES and stores that PTS in the buffer. Control circuitry empties the buffer of an oldest GOP in the video PES if the PCR is greater than the PTS of a second oldest GOP stored in the buffer, and empties the buffer of each PES packet of the audio PES that has a PTS that is less than the PTS of the oldest GOP stored.

  • Patent number: 10325927
    Abstract: Single gate and dual gate FinFET devices suitable for use in an SRAM memory array have respective fins, source regions, and drain regions that are formed from portions of a single, contiguous layer on the semiconductor substrate, so that STI is unnecessary. Pairs of FinFETs can be configured as dependent-gate devices wherein adjacent channels are controlled by a common gate, or as independent-gate devices wherein one channel is controlled by two gates. Metal interconnects coupling a plurality of the FinFET devices are made of a same material as the gate electrodes. Such structural and material commonalities help to reduce costs of manufacturing high-density memory arrays.

  • Patent number: 10324254
    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.

  • Patent number: 10319647
    Abstract: An analog integrated circuit is disclosed in which short channel transistors are stacked on top of long channel transistors, vertically separated by an insulating layer. With such a design, it is possible to produce a high density, high power, and high performance analog integrated circuit chip including both short and long channel devices that are spaced far enough apart from one another to avoid crosstalk. In one embodiment, the transistors are FinFETs and the long channel devices are multi-gate FinFETs. In one embodiment, single and dual damascene devices are combined in a multi-layer integrated circuit cell. The cell may contain various combinations and configurations of the short and long-channel devices. A high density cell can be made by simply shrinking the dimensions of the cells and replicating two or more cells in the same size footprint as the original cell.
