Work function layers for transistor gate electrodes |
| abstract |
Embodiments described herein relate to a method for the fabrication of transistors having aluminum-free n-type work function layers, as opposed to aluminum-based n-type work function layers. The method includes forming a channel portion disposed between the spaced apart source/drain epitaxial layers and forming a gate stack over the channel portion, the step of forming the gate stack comprising: depositing a -k dielectric layer and depositing a p-type work function layer over the dielectric layer. After depositing the p-type work function layer, the method comprises the steps of forming an aluminum-free n-type work function layer on the p-type work function layer and an aluminum-free n-type work function layer without vacuum break. depositing a metal on the work function layer. The method further includes depositing an insulating layer to surround the spaced apart source/drain epitaxial layers and the gate stack. |
