  • Publication number: 20240006267
    Abstract: An example semiconductor package comprises a ceramic header having a top surface and a cavity formed within the ceramic header. The cavity is open at the top surface. A semiconductor die is mounted within the cavity of the ceramic header. A lid structure is coupled to the top surface of the ceramic header. The lid structure and ceramic header form a portion of a package enclosing the semiconductor die. One or more silver tubes are in contact with a first surface of the semiconductor die and with a first surface of the lid structure. A seal ring is located between the top surface of the ceramic header and the lid structure. The seal ring couples the lid structure to the ceramic header. The one or more silver tubes are hollow and filled with a getter material.
