Abstract
A semiconductor device structure includes nanostructures formed over a substrate. The structure also includes a fin isolation structure formed beside the nanostructures. The structure also includes a work function layer surrounding the nanostructures and covering a sidewall of the fin isolation structure. The structure also includes a gate electrode layer covering the work function layer. The gate electrode layer has an extending portion surrounded by the work function layer.
