  • Patent number: 12374616
    Abstract: A method for forming a semiconductor device includes providing a base device having a top dielectric layer, forming a sacrificial layer on the top dielectric layer, and patterning the sacrificial layer to form openings. The method also includes depositing first protective dielectric layer and a low-K dielectric layer in the opening and performing planarization to form a first planarized structure including sacrificial regions and low k regions separated by a first protective layer. Next, top portions of the low-k dielectric layer are replaced with a second protective dielectric layer to form a second planarized structure that includes enclosed dielectric structures separated by sacrificial regions. The method further includes replacing the remaining portions of the sacrificial layer with a target metal interconnect material to form a third planarized structure that includes metal interconnect material disposed between enclosed dielectric structures.

  • Patent number: 12362297
    Abstract: In various embodiments, disclosed herein are systems and methods directed to the fabrication of a coreless semiconductor package (e.g., a millimeter (mm)-wave antenna package) having an asymmetric build-up layer count that can be fabricated on both sides of a temporary substrate (e.g., a core). The asymmetric build-up layer count can reduce the overall layer count in the fabrication of the semiconductor package and can therefore contribute to fabrication cost reduction. In further embodiments, the semiconductor package (e.g., a millimeter (mm)-wave antenna packages) can further comprise dummification elements disposed near one or more antenna layers. Further, the dummification elements disposed near one or more antenna layers can reduce image current and thereby increasing the antenna gain and efficiency.
