  • Publication number: 20250118703
    Abstract: A semiconductor chip is covered by a non-LDS encapsulation material (i.e., encapsulation material not including LDS-activatable additives). One or more first pathways are opened towards the semiconductor chip through the non-LDS encapsulation material. LDS encapsulation material (i.e., encapsulation material including LDS-activatable additives) is molded over the non-LDS encapsulation material to fill the first pathways. One or more second pathways, aligned with the first pathways, are opened towards the semiconductor chip through the LDS encapsulation material. The second pathways have an inner lining of LDS encapsulation material. Electrical coupling formations for the semiconductor chip are provided via laser direct structuring processing of the LDS encapsulation material including the inner lining in the second pathways.

  • Publication number: 20240332238
    Abstract: Laser direct structure (LDS) material is molded onto a semiconductor chip arranged on a substrate. The LDS material has a first thickness between a front surface of the LDS material and the substrate. A portion of the LDS material is removed (with a blade, for instance) to form a cavity having an end wall between the front surface of the LDS material and an electrically conductive formation on the substrate. At the cavity, the LDS material has a second thick ness smaller than the first thickness. Laser beam energy is applied to the LDS material at the end wall of the cavity to structure therein one or more vias that extend between the end wall of the cavity and the electrically conductive formation. The semiconductor chip and the electrically conductive formation are electrically coupled with electrically conductive material grown in the one or more vias laser structured in the LDS material.

  • Publication number: 20240162175
    Abstract: The present disclosure is directed to embodiments of a conductive structure on a conductive barrier layer that separates the conductive structure from a conductive layer on which the conductive barrier layer is present. A gap or crevice extends along respective surfaces of the conductive structure and along respective surfaces of one or more insulating layers. The gap or crevice separates the respective surfaces of the one or more insulating layers from the respective surfaces of the conductive structure. The gap or crevice provides clearance in which the conductive structure may expand into when exposed to changes in temperature. For example, when coupling a wire bond to the conductive structure, the conductive structure may increase in temperature and expand into the gap or crevice. However, even in the expanded state, respective surfaces of the conductive structure do not physically contact the respective surfaces of the one or more insulating layers.
