  • Patent number: 12170256
    Abstract: A method for fabricating a semiconductor product includes forming a dielectric layer over a top level metallization layer of a semiconductor process wafer. The dielectric layer is patterned using a grayscale mask process to define a contact pad opening in the dielectric layer, thereby producing a patterned dielectric layer in which the contact pad opening is aligned to a contact pad defined in the top level metallization layer. A metal layer is deposited over the patterned dielectric layer, including within the contact pad opening. A portion of the metal layer is removed by a chemical mechanical polishing (CMP) process, with a remaining portion of the metal layer having a sloped sidewall.

  • Patent number: 12154956
    Abstract: Disclosed are a structure with a multi-level field plate and a method of forming the structure. The field plate includes multiple first conductors on a dielectric layer and separated from each other by spaces with different widths (e.g., by with progressively decreasing widths). A conformal additional dielectric layer extends over the first conductors and onto the dielectric layer within the spaces. The field plate also includes, on the additional dielectric layer, second conductor(s) with portions thereof extending into the spaces. Within the spaces, the second conductor portions are at different heights (e.g., at progressively increasing heights) above the dielectric layer. Such a field plate can be incorporated into a transistor (e.g., a high electron mobility transistor (HEMT)) to, not only reduce the peak of an electric field exhibited proximal to a gate terminal, but to ensure the electric field is essentially uniform level between the gate and drain terminals.
