| 简介 |
A semiconductor device, such as a transistor or capacitor is provided. The device includes a substrate, a gate dielectric over the substrate, and a conductive gate dielectric film over the gate dielectric. The gate dielectric includes a doped hafnium zirconium oxide containing one or more dopant elements selected from Group II, Group XIII, silicon, and rare earth elements of the Periodic Table. According to one embodiment, the conductive gate dielectric can contain doped hafnium zirconium nitride or doped hafnium zirconium oxynitride. |
