  • Publication number: 20240131555
    Abstract: A deposition apparatus includes: a support module having a plurality of support parts coupled to a target substrate; a base substrate coupled to the support module; a connection member for connecting the plurality of support parts to the base substrate; and a mask assembly configured to mask a deposition material provided to the target substrate. The support module further includes position control parts, which control the plurality of support parts to be movable along a direction axis perpendicular to a major surface of each of the support parts, respectively.

  • Publication number: 20230327350
    Abstract: In a general aspect, an electronic device assembly includes a substrate arranged in a plane. The substrate has a first side and a second side, the second side being opposite the first side. The assembly also includes a plurality of semiconductor die disposed on the first side of the substrate and at least one signal pin. The at least one signal pin includes a proximal end portion coupled with the first side of the substrate, a distal end portion, and a medial portion disposed between the proximal end portion and the distal end portion. The medial portion is pre-molded in a molding compound, the proximal end portion and the distal end portion exclude the molding compound. The at least one signal pin is arranged along a longitudinal axis that is orthogonal to the plane of the substrate.

  • Publication number: 20220406684
    Abstract: Implementations of a semiconductor package may include one or more semiconductor die directly coupled to only a direct leadframe attach (DLA) leadframe including two or more leads; and a coating covering the one or more semiconductor die and the DLA leadframe where when the semiconductor package is coupled into an immersion cooling enclosure, the coating may be in contact with a dielectric coolant while the two or more leads extend out of the immersion cooling enclosure.

  • Patent number: 7723187
    Abstract: A salicide treatment is performed on a common source line to reduce surface resistance and contact resistance, thereby improving a cell current characteristic. Therefore, a chip can be reduced in size and chips per wafer can be increased, thereby achieving high yield. In addition, it is possible to overcome the structural limitation of the flash cell when the semiconductor memory device is highly integrated and shrunken.
