  • Publication number: 20230056222
    Abstract: A semiconductor package may be presented. The semiconductor package includes a first dielectric layer including a first surface and a second surface. First and second conductive lands are disposed on the first surface of the first dielectric layer. A first column formed by the first conductive lands and a second column formed by the second conductive lands are spaced apart from each other. Outer traces extend from the second conductive lands, and inner traces are disposed on the second surface of the first dielectric layer. Vias penetrate the first dielectric layer and respectively connect the first conductive lands to the inner traces. A semiconductor die is disposed on the first surface of the first dielectric layer.

  • Publication number: 20230034877
    Abstract: Provided is a method of manufacturing a semiconductor device including a bump interconnect structure. In the method of manufacturing the semiconductor device, a first substrate including a connection pad is formed, and a bump including a solder layer and a metal post protruding from the solder layer are formed on the connection pad. A second substrate including a bump land may be formed. The first substrate may be disposed on the second substrate so that a protruding end of the metal post contacts the bump land, and the solder layer may be reflowed. Accordingly, it possible to interconnect the metal post to the bump land.
