  • Publication number: 20230411208
    Abstract: Methods of forming semiconductor devices including an air gap extending through at least one metal layer, and the semiconductor device so formed, are disclosed. The air gap has a lower portion that contacts a silicide layer over a gate body of a transistor gate and has an inverted T-shape over the gate body. The air gap reduces the capacitance between a transistor gate in a device layer and adjacent wires and vias used to contact the source and drain of the transistor.

  • 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.

  • Patent number: 9236391
    Abstract: Fabrication of a slim split gate cell and the resulting device are disclosed. Embodiments include forming a first gate on a substrate, the first gate having an upper surface and a hard-mask covering the upper surface, forming an interpoly isolation layer on side surfaces of the first gate and the hard-mask, forming a second gate on one side of the first gate, with an uppermost point of the second gate below the upper surface of the first gate, removing the hard-mask, forming spacers on exposed vertical surfaces, and forming a salicide on exposed surfaces of the first and second gates.
