    Abstract: A one-time programmable (OTP) fuse includes a fuse link including a thin film resistor (TFR) layer between a first insulator layer and a second insulator layer. A first terminal of the OTP fuse includes a first conductive pillar through one of the first and second insulator layers and in contact with the TFR layer; and a second terminal of the OTP fuse includes a second conductive pillar through one of the first and second insulator layers and in contact with the TFR layer. The second conductive pillar and the TFR layer have a lateral contact interface having a same shape as an outer portion of the second conductive pillar. The second conductive pillar does not simply land on the TFR layer, but extends through it. Application of a current to the OTP fuse results in programming via rupture of the lateral contact interface (not electromigration in the fuse link).

    Abstract: A device may include a substrate, and an interlevel dielectric arranged over the substrate. The interlevel dielectric may include a first interlevel dielectric layer in an interconnect level i, the first interlevel dielectric layer having a first interconnect and a second interconnect therein. A nitride block insulator may be arranged over the first interlevel dielectric layer and over the first interconnect and the second interconnect. An opening may be arranged in the nitride block insulator, the opening extending through the nitride block insulator to expose a surface of the first interconnect in the first interlevel dielectric layer. A contact plug may be arranged in the opening of the nitride block insulator. The contact plug at least lines the opening and prevents out-diffusion of conductive material from the first interconnect. A thin film of a passive component may be arranged over the nitride block insulator and over the contact plug.

    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.
