  • Publication number: 20250079283
    Abstract: A package structure includes a first semiconductor die, a second semiconductor die, an insulating encapsulant and a redistribution layer. The insulating encapsulant laterally surrounds the first semiconductor die and the second semiconductor die, wherein the insulating encapsulant includes a first portion sandwiched in between the first semiconductor die and the second semiconductor die, the first portion has a first recessed part adjacent to an edge of the first semiconductor die, and a second recessed part adjacent to an edge of the second semiconductor die. The redistribution layer is disposed on and electrically connected to the first semiconductor die and the second semiconductor die.

  • Publication number: 20240063081
    Abstract: A package structure including a semiconductor die, an encapsulant, a redistribution structure, and a through insulating via is provided. The first redistribution structure includes an insulating layer and a circuit layer. The semiconductor die is disposed on the first redistribution structure. The semiconductor die includes a semiconductor base, through semiconductor vias, a dielectric layer, and bonding connectors. Through semiconductor vias penetrate through the semiconductor base. The dielectric layer is disposed on a backside of the semiconductor base. The dielectric layer of the semiconductor die is bonded with the insulating layer of the first redistribution structure. The bonding connectors are embedded in the dielectric layer and connected to the through semiconductor vias. The bonding connectors of the semiconductor die are bonded with bonding pads of the circuit layer. The encapsulant is disposed on the first redistribution structure and encapsulates the semiconductor die.

  • Publication number: 20240038626
    Abstract: A semiconductor package includes a first redistribution circuit structure, a semiconductor die, and an electrically conductive structure. The semiconductor die is disposed over and electrically coupled to the first redistribution circuit structure. The electrically conductive structure connects a non-active side of the semiconductor die to a conductive feature of the first redistribution circuit structure, where the semiconductor die is thermally couped to the first redistribution circuit structure through the electrically conductive structure, and the electrically conductive structure includes a structure of multi-layer with different materials.
