  • Patent number: 11810859
    Abstract: Structures are described that include multi-layered adhesion promotion films over a conductive structure in a microelectronic package. The multi-layered aspect provides adhesion to surrounding dielectric material without a roughened surface of the conductive structure. Furthermore, the multi-layered aspect allows for materials with different dielectric constants to be used, the average of which can provide a closer match to the dielectric constant of the surrounding dielectric material. According to an embodiment, a first dielectric layer that includes at least one nitride material can provide good adhesion with the underlying conductive structure, while one or more subsequent dielectric layers that include at least one oxide material can provide different dielectric constant values (e.g., typically lower) compared to the first dielectric layer to bring the overall dielectric constant closer to that of a surrounding dielectric material.
