Abstract
A semiconductor device includes a substrate; a first fin structure extending along a first lateral direction; a second fin structure extending along the first lateral direction; a first gate structure extending along a second lateral direction and straddles the first fin structure; a second gate structure extending along the second lateral direction and straddles the second fin structure. The semiconductor device further includes a dielectric cut structure that separates the first and second gate structures from each other. The dielectric cut structure extends into the substrate and comprises a first portion and a second portion. A width of the first portion along the second lateral direction increases with increasing depth into the substrate and a width of the second portion along the second lateral direction decreases with increasing depth into the substrate. The second portion is located below the first portion.
