  • Publication number: 20240429156
    Abstract: A device includes a first dielectric layer. A second dielectric layer is disposed over the first dielectric layer. The second dielectric layer and the first dielectric layer have different material compositions. A metal-insulator-metal (MIM) structure is embedded in the second dielectric layer. A third dielectric layer is disposed over the second dielectric layer. The third dielectric layer and the second dielectric layer have different material compositions. The first dielectric layer or the third dielectric layer may contain silicon nitride (SiN), the second dielectric layer may contain silicon oxide (SiO2).

  • Publication number: 20240363339
    Abstract: Generally, the present disclosure provides example embodiments relating to conductive features, such as metal contacts, vias, lines, etc., and methods for forming those conductive features. In a method embodiment, a dielectric layer is formed on a semiconductor substrate. The semiconductor substrate has a source/drain region. An opening is formed through the dielectric layer to the source/drain region. A silicide region is formed on the source/drain region and a barrier layer is formed in the opening along sidewalls of the dielectric layer by a same Plasma-Enhance Chemical Vapor Deposition (PECVD) process.

  • Publication number: 20240249948
    Abstract: The present disclosure relates to a method for fabricating a semiconductor structure. The method includes providing a substrate with a gate structure, an insulating structure over the gate structure, and a S/D region; depositing a titanium silicide layer over the S/D region with a first chemical vapor deposition (CVD) process. The first CVD process includes a first hydrogen gas flow. The method also includes depositing a titanium nitride layer over the insulating structure with a second CVD process. The second CVD process includes a second hydrogen gas flow. The first and second CVD processes are performed in a single reaction chamber and a flow rate of the first hydrogen gas flow is higher than a flow rate of the second hydrogen gas flow.
