  • Patent number: 11974472
    Abstract: A display substrate and a manufacturing method and a display device are provided. The display substrate includes: a base substrate, a first insulation layer, a first electrode pattern, a connecting electrode pattern, a second electrode, a light-emitting functional layer, and a first filling layer. The second electrode is connected with the connecting electrode pattern, the second electrode and the first electrode pattern are spaced apart from each other. The light-emitting functional layer is located between the first electrode pattern and the second electrode. The first filling layer is located between the connecting electrode pattern and the first electrode pattern. The first filling layer and the light-emitting functional layer are different layers; a portion of the first insulation layer that is located between the first electrode pattern and the connecting electrode pattern has a groove, and the first filling layer is at least partially located in the groove.

  • Patent number: 9947606
    Abstract: A semiconductor device is disclosed including material for absorbing EMI and/or RFI. The device includes a substrate, one or more semiconductor die, and molding compound around the one or more semiconductor die. The material for absorbing EMI and/or RFI may be provided within or on a solder mask layer on the substrate, or within a dielectric core of the substrate. The device may further include EMI/RFI-absorbing material around the molding compound and in contact with the EMI/RFI-absorbing material on the substrate to completely enclose the one or more semiconductor die in EMI/RFI-absorbing material.

  • Publication number: 20150187745
    Abstract: A semiconductor device, and a method of its manufacture, are disclosed. The semiconductor device includes a semiconductor die, such as a controller die, mounted on a surface of a substrate. Pillars, for example of solder, may also formed on the substrate, around the semiconductor die. The pillars are formed to a height above the substrate that is greater than the height of the substrate-mounted semiconductor die, including any wire bonds, above the substrate. A second group of one or more semiconductor die, such as flash memory die, may be affixed to the substrate, on top of the solder pillars without contacting the substrate-mounted semiconductor die.
