Abstract

A semiconductor device includes a structure on a substrate and a plurality of gate-all-around devices on the structure. The structure includes a plurality of sacrificial layers and a plurality of active layers alternately stacked on one another. The sacrificial layers have different widths and the active layers have different widths to form multiple stepped layers on the substrate. The gate-all-around devices are on respective ones the multiple stepped layers.
