  • Publication number: 20230132054
    Abstract: Disclosed is a semiconductor package including a package substrate, a semiconductor chip mounted on the package substrate, a connection solder pattern between the package substrate and the semiconductor chip, and a dummy bump between the package substrate and the semiconductor chip and spaced apart from the connection solder pattern. The connection solder pattern includes a first intermetallic compound layer, a connection solder layer, and a second intermetallic compound layer. The dummy bump includes a dummy pillar and a dummy solder pattern. A thickness of the dummy solder pattern is less than a thickness of the connection solder pattern. A melting point of the dummy solder pattern is greater than that of the connection solder layer.

  • Publication number: 20230099351
    Abstract: A semiconductor package includes a lower substrate having a chip mounting region, an interconnection region surrounding the chip mounting region, and an outer region surrounding the interconnection region, and includes a lower wiring layer. A first solder resist pattern has first openings exposing bonding regions of the lower wiring layer. A semiconductor chip is on the chip mounting region and is electrically connected to the lower wiring layer. A second solder resist pattern is on the first solder resist pattern on the interconnection and outer regions and is spaced apart from the semiconductor chip, and includes second openings disposed on the first openings. An upper substrate covers the semiconductor chip, and includes an upper wiring layer. A vertical connection structure is on the interconnection region and electrically connects the upper and lower wiring layers. A solder resist spacer is on the second solder resist pattern on the outer region.

  • Patent number: 11229124
    Abstract: The present invention relates to a method for formation of a redistribution layer using photo-sintering and to the redistribution layer formed by the method. The method for forming a redistribution layer using photo-sintering includes printing, on a substrate, a liquid electrode pattern for a redistribution layer; coating a transparent polymer on the substrate and the pattern; photo-sintering the electrode pattern using photonic energy; and evaporating an organic substance contained in the liquid electrode pattern via the photo-sintering to remove the polymer on a top face of the electrode pattern to form a redistribution layer as the sintered electrode pattern.
