    Abstract: A method includes depositing a semiconductor stack within a first region and a second region on a substrate, the semiconductor stack having alternating layers of a first type of semiconductor material and a second type of semiconductor material. The method further includes removing a portion of the semiconductor stack from the second region to form a trench and with an epitaxial growth process, filling the trench with the second type of semiconductor material. The method further includes patterning the semiconductor stack within the first region to form a nanostructure stack, patterning the second type of semiconductor material within the second region to form a fin structure, and forming a gate structure over both the nanostructure stack and the fin structure.

    Abstract: A semiconductor structure includes a first active region over a substrate and extending along a first direction, a gate structure over the first active region and extending along a second direction substantially perpendicular to the first direction, a gate-cut feature abutting an end of the gate structure, and a channel isolation feature extending along the second direction and between the first active region and a second active region. The gate structure includes a metal electrode in direct contact with the gate-cut feature. The channel isolation feature includes a liner on sidewalls extending along the second direction and a dielectric fill layer between the sidewalls. The gate-cut feature abuts an end of the channel isolation feature and the dielectric fill layer is in direct contact with the gate-cut feature.
