  • Publication number: 20240133038
    Abstract: Methods of forming a structural color metal-dielectric-metal (MDM) component via a solution-based process are provided. First, a first metal layer is formed over a treated surface of a substrate by a first electroless deposition process. A surface of the treated substrate is contacted with a first plating bath that comprises a metal selected from the group consisting of: copper, aluminum, silver, alloys, and combinations thereof. A dielectric layer, for example, comprising silicon dioxide, is then deposited over the first metal layer by a sol-gel process. Next, the method comprises forming a second metal layer over the dielectric layer by a second electroless deposition process by contacting the dielectric layer with a second plating bath having a neutral pH and comprising a metal selected from the group consisting of: copper, aluminum, silver, alloys, and combinations thereof.

  • Patent number: 11545486
    Abstract: The present disclosure relates to semiconductor structures and, more particularly, to an integrated thin film resistor with a metal-insulator-metal capacitor and methods of manufacture. The structure includes: a first buffer contact on a substrate; a second buffer contact on the substrate, the second buffer contact being on a same wiring level as the first buffer contact; a resistive film contacting the first buffer contact and the second buffer contact, the resistive film extending on the substrate between the first buffer contact and the second buffer contact; and electrical contacts landing on both the first buffer contact and the second buffer contact, but not directly contacting with the resistive film.

  • Patent number: 11056430
    Abstract: According to various embodiments, a semiconductor device may include a thin film arranged within a first inter-level dielectric layer, a masking region, and a contact plug. The masking region may be arranged over the thin film, within the first inter-level dielectric layer. The masking region may be structured to have a higher etch rate than the first inter-level dielectric layer. The contact plug may extend along a vertical axis, from a second inter-level dielectric layer to the thin film. A bottom portion of the contact plug may be surrounded by the masking region. The bottom portion of the contact plug may include a lateral member that extends along a horizontal plane at least substantially perpendicular to the vertical axis. The lateral member may be in contact with the thin film.
