  • Publication number: 20240404857
    Abstract: Base plates of a substrate retainer transportation mechanism are provided with damping members to assist elastic members in damping and limiting movement of the substrate retainer transportation mechanism when the substrate transportation mechanism is subjected to unwanted external forces, e.g., seismic forces. By damping and limiting movement of the substrate retainer transportation mechanism, undesirable damage to substrates contained in a substrate retainer being carried by the substrate retainer transport mechanism can be minimized.

  • 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.
