  • Publication number: 20200066669
    Abstract: A thermal interface material and systems and methods for forming a thermal interface material include depositing a layer of a composite material, including at least a first material and a second material, the first material including a carrier fluid and the second material including a filler particle suspended within the first material. A particle manipulator is positioned over the layer of the composite material, the particle manipulator including at least one emitter to apply a particle manipulating field to bias a movement of the filler particles. The second material is redistributed by applying the particle manipulating field to interact with the second material causing the second material to migrate from a surrounding region in the composite material into a high concentration region in the composite material to form a customized thermal interface such that the high concentration region is configured and positioned corresponding to a hotspot.

  • Publication number: 20200027840
    Abstract: A method for fabricating semiconductor wafers comprises creating a semiconductor wafer having a plurality of wide copper wires and a plurality of narrow copper wires embedded in a dielectric insulator. The width of each wide copper wire is greater than a cutoff value and each narrow copper is less than the cutoff value. An optical pass through layer is deposited over a top surface of the wafer and a photo-resist layer is deposited over the optical pass through layer. The wafer is exposed to a light source to selectively remove photo-resist, forming a self-aligned pattern where photo-resist only remains in areas above wide copper wires. The self-aligned pattern is transferred to the optical pass through layer and the remaining photo-resist is removed. The wafer is chemically etched to remove the narrow copper wires, defining narrow gaps in the dielectric insulator. The wafer is metallized with non-copper metal, forming narrow non-copper metal wires.

    Abstract: A method of forming a self-aligned pattern of vias in a semiconductor device comprises etching a pattern of lines that contain notches that are narrower than other parts of the line. Thereafter, vias are created where the notches are located. The locations of the vias are such that the effect of blown-out areas is minimized. Thereafter, the lines are etched and the vias and line areas are filled. The layers are planarized such that the metal fill is level with a surrounding ultra-low-k dielectric. Additional metal layers, lines, and vias can be created. Other embodiments are also described herein.
