  • Patent number: 11101199
    Abstract: A power semiconductor device is such that a notch provided, along a longitudinal end face of an inner lead, in a region of a lead frame to which the inner lead is bonded. A resistor is disposed, adjacent to the inner lead, on the same side as the notch with respect to the inner lead, and a distance between the inner lead and the notch is set to be smaller than a distance between the inner lead and the resistor, and thereby the inner lead, even when shifted in position, comes into no contact with the resistor. Because of this, it is no more necessary that a space be provided around the inner lead taking into consideration a positional shift of the inner lead, and it is possible to secure the heat release area of power semiconductor chips accordingly, and thus to obtain the small-sized and high-powered power semiconductor device.

  • Patent number: 10930581
    Abstract: Embodiments of the present disclosure are directed to flat no-lead packages with wettable sidewalls or flanks. In particular, wettable conductive layers are formed on the package over lateral portions of the leads and on portions of the package body, which may be encapsulation material. The wettable conductive layers may also be formed on bottom surfaces of the package body and the leads. The wettable conductive layers provide a wettable flank for solder to wick up when the package is mounted to a substrate, such as a PCB, using SMT. In particular, solder that is used to join the PCB and the package wicks up the side of the wettable conductive layers along a side surface of the package. In that regard, the solder is exposed and coupled to the side surface of the package at the wettable conductive layers, thereby allowing for a visual inspection of the solder joints. The wettable conductive layers are formed on the package after the package body has been formed.

    Abstract: A lead frame includes, as an outermost plating layer, a roughened silver plating layer having acicular projections and covering top faces and faces that form concavities or a through hole between the top faces and bottom faces of a lead frame substrate made of a copper-based material. The roughened silver plating layer has a crystal structure in which the crystal direction <101> occupies a largest proportion among the crystal directions <001>, <111>, and <101>. The lead frame can be manufactured with improved productivity owing to reduction in cost and operation time, and achieves remarkably high adhesion to sealing resin while keeping the total thickness of plating layers including the silver plating layer to be thin.

  • Patent number: 10895682
    Abstract: Photonic circuits are disclosed having an efficient optical power distribution network. Laser chips (InP) having different wavelengths are flip-chip assembled near the center of a silicon photonic chip. Each InP die has multiple optical lanes, but a given die has only one wavelength. Waveguides formed in the photonic chip are optically connected to the lanes, and fan out to form multiple waveguide sets, where each waveguide set has one of the waveguides from each of the different wavelengths, i.e., one waveguide from each InP die. The waveguide network is optimized to minimize the number of crossings that any given waveguide may have, and no waveguide having a particular wavelength crosses another waveguide of the same wavelength. The unique arrangements of light sources and waveguides allows the use of a smaller number of more intense laser sources, particularly in applications such as performance-optimized datacenters where liquid cooling systems may be leveraged.
