    Abstract: A method includes doping a substrate with a dopant to form a first well region of a first core circuit and a second well region of a second core circuit; forming first and second semiconductor fins respectively over the first and second well regions and extending along a direction; forming a first gate stack across the first semiconductor fin and a second gate stack across the second semiconductor fin; forming a first source/drain adjoining the first semiconductor fin and a second source/drain adjoining the second semiconductor fin; and forming a first contact over the first source/drain and having a first width measured along the direction and a second contact over the second source/drain and having a second width measured along the direction, wherein the second width of the second contact is greater than the first width of the first contact.

    Abstract: A semiconductor device includes a substrate, a semiconductor fin, first and second source/drains, a gate electrode, and a gate contact. The semiconductor fin is disposed on the substrate. The first and second source/drains is disposed on the semiconductor fin. The gate electrode is across the semiconductor fin and exposes the first and second source/drains. The gate contact is disposed on the gate electrode and has an elliptical profile with a major axis extending along a lengthwise direction of the gate electrode when viewed from above the gate contact.

    Abstract: An integrated circuit (IC) structure includes first and second semiconductor channel patterns extending over a substrate. From a plan view, the second semiconductor channel pattern has a longitudinal axis aligned with a longitudinal axis of the first semiconductor channel pattern, the first semiconductor channel pattern has a first longitudinal side and a second longitudinal side separated from the first longitudinal side by a first distance, and the second channel pattern has a third longitudinal side and a fourth longitudinal side separated from the third longitudinal side by a second distance less than the first distance.

    Abstract: A semiconductor device includes circuit cells having transistors. Each of the transistors includes nanostructures vertically stacked from each other in a Z-direction, a gate structure wrapping around the nanostructures and extending in a Y-direction, and source/drain features on opposite sides of the gate structure in an X-direction. The semiconductor device further includes silicide features over and in contact with the source/drain features. The silicide features extend lower than bottom surfaces of topmost nanostructures of the nanostructures. The semiconductor device further includes source/drain contacts over and in contact with the silicide features. Each of bottom surfaces of the source/drain contacts has a V-shape in an X-Z cross-sectional view.

    Abstract: A method for manufacturing a semiconductor device includes forming first and second semiconductor fins extending upwardly from a substrate; forming a dielectric fin between the first and second semiconductor fins; forming a shallow trench isolation (STI) structure laterally surrounding lower portions of the first and second semiconductor fins and the dielectric fin; forming a gate strip extending across upper portions of the first semiconductor fin, the dielectric fin, and the second semiconductor fin; patterning the gate strip to form a first gate structure extending across the first semiconductor fin and a second gate structure extending across the second semiconductor fin while leaving the dielectric fin uncovered; and after patterning the gate strip, depositing a high-k dielectric material over the dielectric fin and in contact with a longitudinal end of the first gate structure and a longitudinal end of the second gate structure.
