  • Patent number: 10727131
    Abstract: The present disclosure describes a method to form silicon germanium (SiGe) source/drain regions with the incorporation of a lateral etch in the epitaxial source/drain growth process. For example, the method can include forming a plurality of fins on a substrate, where each of the plurality of fins has a first width. The SiGe source/drain regions can be formed on the plurality of fins, where each SiGe source/drain region has a second width in a common direction with the first width and a height. The method can also include selectively etching—e.g., via a lateral etch—the SiGe source/drain regions to decrease the second width of the SiGe source/drain regions. By decreasing the width of the SiGe source/drain regions, electrical shorts between neighboring fins can be prevented or minimized. Further, the method can include growing an epitaxial capping layer over the Si/Ge source/drain regions.

  • Publication number: 20200185124
    Abstract: A high-speed flat cable having a better bending/folding memory and a manufacturing method thereof are provided. The high-speed flat cable includes a plurality of shielded signal units, one or more bendable composite layers, and an adhesive layer. The shielded signal units are substantially coplanar, spaced apart from each other or adjoining each other. The one or more bendable composite layers includes an inner insulating film layer, a bendable aluminum foil layer, and an outer insulating film layer. The one or more bendable composite layers composed of the inner insulating film layer, the bendable aluminum foil layer, and the outer insulating film layer increase its mechanical bending/folding property to improve the bending/folding memory. The one or more bendable composite layers allow the flat cable to be bent with ease without rebounding, thereby enhancing production efficiency.

  • Publication number: 20200154599
    Abstract: The disclosure relates to a heat dissipation module, a display device having the same, and an assembly method thereof. Place the heat dissipation structure in between the chip of the COF (chip-on-film) and the thermal-conductive supporting component, heat generated by the chip of the COF can be absorbed by the heat dissipation structure and then be transferred to the thermal-conductive supporting component through the heat dissipation structure. As a result, the temperature of the chip is decreased, and the chip is avoided from operating at high temperature to deteriorate its performance and to result in thermal deformation or any other negative effects on the nearby components.

  • Publication number: 20200076132
    Abstract: A connector assembly configured for compact, high speed electronic systems. The assembly includes a board connector and a cable connector that may be mated by moving the cable connector in a mating direction perpendicular to a printed circuit board to which the board connector is mounted. The cable and board connectors may latch when mated and may be unlatched and unmated by pulling on a tab at a top of the cable connector in a direction opposite the mating direction. As a result, little clearance is required around the board connector to access the latching components. Such a connector may enable an electronic device with high signal integrity because the connector can be mounted close to an electronic component that processes high speed signals, providing a short, and high integrity signal paths for high speed signals.

  • Publication number: 20200076126
    Abstract: A connector assembly with latching provided by a rotating latch bar. The connector has a low height, with the rotating latch bar providing secure engagement between mated connectors of the connector assembly. The latch bar may be shaped to provide spring force that urges the mated connectors together. The connector assembly may be formed with a cable connector and a board connector. The low height of the board connector enables the connector to be mounted close to high speed electronic components, such as a processor, even if covered by a heat sink, as the connector may fit under the heat sink. The cable connector may be coupled, via a cable, to an I/O connector or other component remote from the high speed electronic component.
