  • Publication number: 20240429304
    Abstract: A dummy gate structure is formed over a plurality of active regions. The dummy gate structure extends in a first horizontal direction in a planar top view. The active regions each extend in a second horizontal direction in the planar top view. The second horizontal direction is different from the first horizontal direction. A plurality of source/drain components is formed over the active regions. A dielectric structure is formed over the source/drain components. The dummy gate structure is then removed. A removal of the dummy gate structure exposes a first segment of each of the active regions. A thickness of the first segment of each of the active regions is reduced in the first horizontal direction.

  • Patent number: 12164235
    Abstract: Some implementations described herein include operating components in a lithography system at variable speeds to reduce, minimize, and/or prevent particle generation due to rubbing of or collision between contact parts of the components. In some implementations, a component in a path of transfer of a semiconductor substrate in the lithography system is operated at a relatively high movement speed through a first portion of an actuation operation, and is operated at a reduced movement speed (e.g., a movement speed that is less than the high movement speed) through a second portion of the actuation operation in which contact parts of the component are to interact. The reduced movement speed reduces the likelihood of particle generation and/or release from the contact parts when the contact parts interact, while the high movement speed provides a high semiconductor substrate throughput in the lithography system.

  • 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.

  • Publication number: 20240371704
    Abstract: An anchored cut-metal gate (CMG) plug, a semiconductor device including the anchored CMG plug and methods of forming the semiconductor device are disclosed herein. The method includes performing a series of etching processes to form a trench through a metal gate electrode, through an isolation region, and into a semiconductor substrate. The trench cuts-through and separates the metal gate electrode into a first metal gate and a second metal gate and forms a recess in the semiconductor substrate. Once the trench has been formed, a dielectric plug material is deposited into the trench to form a CMG plug that is anchored within the recess of the semiconductor substrate and separates the first and second metal gates. As such, the anchored CMG plug provides high levels of resistance to reduce leakage current within the semiconductor device during operation and allowing for improved V-trigger performance of the semiconductor device.
