  • Publication number: 20240096956
    Abstract: An integrated circuit semiconductor device includes a nanosheet extending above a substrate in a first horizontal direction, a gate electrode extending in a second horizontal direction while surrounding the nanosheet with a gate insulating layer therebetween, a first source/drain region on a side of the nanosheet, and a second source/drain region on another side of the nanosheet, wherein the first source/drain region includes first silicide layers provided inward from surfaces of the nanosheet, first metal layers surrounding the nanosheet from upper and lower sides of the first silicide layers, and a first nanosheet region provided between the first silicide layers, wherein the second source/drain region includes second silicide layers formed inward from the surfaces of the nanosheet, second metal layers surrounding the nanosheet from upper and lower sides of the second silicide layers, and a second nanosheet region provided between the second silicide layers.

  • Publication number: 20230253264
    Abstract: A semiconductor device is provided. The semiconductor device includes a substrate including an active pattern, a gate electrode extending in a first direction and crossing the active pattern which extends in a second direction, a separation structure crossing the active pattern and extending in the first direction, a first gate dielectric pattern disposed on a side surface of the gate electrode, a second gate dielectric pattern disposed on a side surface of the separation structure, and a gate capping pattern covering a top surface of the gate electrode. A level of a top surface of the separation structure is higher than a level of a top surface of the gate capping pattern.
