  • Publication number: 20240145346
    Abstract: A semiconductor device includes a substrate with a conductive pattern. A semiconductor die is electrically connected to the substrate and both the semiconductor die and the substrate are at least partially covered by a package body. In some examples, through-mold vias are formed in the package body to provide electrical signal paths from an exterior surface thereof to the conductive pattern of the substrate. In some examples, through-mold vias are included in the package body to provide electrical signal paths between the semiconductor die and an exterior surface of the package body. In some examples, an interposer is electrically connected to the through-mold vias and may be covered by the package body and/or disposed in spaced relation thereto. In some examples, the interposer may not be electrically connected to the through-mold vias but may have one or more semiconductor dies of the semiconductor device electrically connected thereto.

  • Patent number: 11969397
    Abstract: The present invention relates to a composition for preventing or treating transplantation rejection or a transplantation rejection disease, comprising a novel compound and a calcineurin inhibitor. A co-administration of the present invention 1) reduces the activity of pathogenic Th1 cells or Th17 cells, 2) increases the activity of Treg cells, 3) has an inhibitory effect against side effects, such as tissue damage, occurring in the sole administration thereof, 4) inhibits various pathogenic pathways, 5) inhibits the cell death of inflammatory cells, and 6) increases the activity of mitochondria, in an in vivo or in vitro allogenic model, a transplantation rejection disease model, a skin transplantation model, and a liver-transplanted patient, and thus inhibits transplantation rejection along with mitigating side effects possibly occurring in the administration of a conventional immunosuppressant alone.

  • Patent number: 11961775
    Abstract: In one example, a semiconductor device can comprise a substrate, a device stack, first and second internal interconnects, and an encapsulant. The substrate can comprise a first and second substrate sides opposite each other, a substrate outer sidewall between the first substrate side and the second substrate side, and a substrate inner sidewall defining a cavity between the first substrate side and the second substrate side. The device stack can be in the cavity and can comprise a first electronic device, and a second electronic device stacked on the first electronic device. The first internal interconnect can be coupled to the substrate and the device stack. The encapsulant can cover the substrate inner sidewall and the device stack and can fill the cavity. Other examples and related methods are disclosed herein.

  • Patent number: 10065862
    Abstract: The present invention relates to carbon nanotube fibers reinforced with a carbon precursor and a method for manufacturing the same. The carbon nanotube fibers reinforced with a carbon precursor according to the present invention are carbonized by the empty space inside the carbon nanotube fibers being filled with a carbon precursor, and therefore, are highly effective in that the mechanical and thermal properties are improved due to effective stress transfer and contact resistance decrease, and these properties are maintained intact even at high temperatures.

  • Publication number: 20030107462
    Abstract: A flyback transformer, used as a high voltage generator for supplying a high voltage to the CRT of a TV receiver or a monitor, and a bleeder resistor holding device for such transformers is disclosed. The bleeder resistor holding device is designed to hold a bleeder resistor at a position between a high voltage bobbin and a low voltage bobbin of the transformer, thus accomplishing compactness and smallness of a focus pack of the transformer. In the flyback transformer of this invention, the bleeder resistor is positioned at a gap defined between the pin terminals of the high voltage bobbin and the low voltage bobbin such that the bleeder resistor is spaced apart from the pin terminal of the low voltage bobbin by a predetermined distance.
