Summary: | Horizontal gate-all-around devices and methods of manufacturing same are described. The hGAA devices comprise an oxide layer and a semiconductor material layer between source regions and drain regions of the device. The method includes growing a conformal epitaxial layer on a nanosheet channel layer, followed by radical plasma oxidation (RPO) to oxidize the conformal epitaxial layer. An alternative method includes growing a conformal epitaxial layer on a nanosheet channel layer, followed by a surface treatment, and then radical plasma oxidation (RPO) to oxidize the conformal epitaxial layer. |
