Method for forming long channel back-side power rail device |
| abstract |
A method of forming a semiconductor transistor device is disclosed. The method includes forming a finned channel structure over a substrate, and forming a first source/drain epitaxial structure and a second source/drain epitaxial structure on both ends of the fin structure. The method further includes forming a metal gate structure surrounding the fin structure. The method further includes flipping the substrate and partially removing the backside capped trench while leaving a lower portion of the substrate along the upper sidewalls of the first source/drain epitaxial structure and the second source/drain epitaxial structure as a protective spacer. form The method further includes forming a backside dielectric cap in the backside capping trench. |
