  • Publication number: 20220328309
    Abstract: Embodiments disclosed herein relate generally to capping processes and structures formed thereby. In an embodiment, a conductive feature, formed in a dielectric layer, has a metallic surface, and the dielectric layer has a dielectric surface. The dielectric surface is modified to be hydrophobic by performing a surface modification treatment. After modifying the dielectric surface, a capping layer is formed on the metallic surface by performing a selective deposition process. In another embodiment, a surface of a gate structure is exposed through a dielectric layer. A capping layer is formed on the surface of the gate structure by performing a selective deposition process.

  • Publication number: 20220301944
    Abstract: A high atomic number material is applied to one or more surfaces of a semiconductor structure of a wafer. The one or more surfaces are at a depth different from a depth of a surface of the wafer. An electron beam is scanned over the semiconductor structure to cause a backscattered electron signal to be collected at a collector. A profile scan of the semiconductor structure is generated based on an intensity of the backscattered electron signal, at the collector, resulting from the high atomic number material. The high atomic number material increases the intensity of the backscattered electron signal for the one or more surfaces of the semiconductor structure such that contrast in the profile scan is increased. The increased contrast of the profile scan enables accurate critical dimension measurements of the semiconductor structure.
