  • Patent number: 11923314
    Abstract: A semiconductor package includes a connection structure including a redistribution layer, a plurality of under bump metal layers electrically connected to the redistribution layer, a passivation layer which overlaps at least portions of side faces of the plurality of under bump metal layers, and includes a first trench disposed between under bump metal layers adjacent to each other, a surface mounting element which is on the under bump metal layers adjacent to each other, connected to the redistribution layer, and overlaps the first trench, and an underfill material layer that is between a portion of the passivation layer and the surface mounting element, and is in the first trench. The first trench extends in a first direction and includes a first sub-trench having a first width in a second direction, and a second sub-trench having a second width different from the first width in the second direction.

  • Patent number: 11314120
    Abstract: A coating device includes an upper stage, a lower stage and a spraying part. The upper stage masks an upper surface of a display panel. The lower stage masks a lower surface of the display panel. The spraying part sprays ink to a side surface of the display panel. The side surface of the display panel is exposed between the upper stage and the lower stage. The coating device includes the upper stage and the lower stage, so that the coating device may form a coating layer of uniform thickness by precisely spraying ink. In addition, a cross-section of the coating layer may be precisely formed having specific shape such as an L or C shape. A display apparatus having high light usage efficiency and reduced light leakage may be provided by using the coating device.
