Abstract

The present disclosure describes a semiconductor device having a protection layer on inner spacer structures. The semiconductor device includes a nanostructure on a substrate. The nanostructure includes multiple semiconductor layers. The semiconductor device further includes a gate structure wrapped around a middle portion of the multiple semiconductor layers and a spacer structure adjacent to an end portion of the multiple semiconductor layers. The gate structure includes a high-k dielectric layer. The semiconductor device further includes a protection layer between the high-k dielectric layer and the spacer structure.
