  • Publication number: 20240387644
    Abstract: Ruthenium of a metal gate (MG) and/or a middle end of line (MEOL) structure is annealed to reduce, or even eliminate, seams after the ruthenium is deposited. Because the annealing reduces (or removes) seams in deposited ruthenium, electrical performance is increased because resistivity of the MG and/or the MEOL structure is decreased. Additionally, for MGs, the annealing generates a more even deposition profile, which results in a timed etching process producing a uniform gate height. As a result, more of the MGs will be functional after etching, which increases yield during production of the electronic device.
