SEMICONDUCTOR DEVICE STRUCTURE

This abstract first appeared for US patent application 20250120139 titled 'SEMICONDUCTOR DEVICE STRUCTURE

Original Abstract Submitted

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.
