Abstract:
According to an exemplary embodiment, a method of forming a vertical structure with at least two barrier layers is provided. The method includes the following operations: providing a substrate; providing a vertical structure over the substrate; providing a first barrier layer over a source, a channel, and a drain of the vertical structure; and providing a second barrier layer over a gate and the drain of the vertical structure.

Claim (Index 36):
A method of manufacturing a semiconductor device, the method comprising:\n forming a first vertical structure and a second vertical structure over a substrate, each including a first source/drain region, a channel region over the first source/drain region and a second source/drain region over the channel region; forming a first barrier layer over the first and second vertical structures; forming an interlayer dielectric layer over the first barrier layer; exposing the channel region and the second source/drain region of each of the first and second vertical structures; forming a gate dielectric layer over the exposed channel region of each of the first and second vertical structures; forming at least two layers of work function adjustment materials on the gate dielectric layer over the first vertical structure, and forming at least one layer of work function adjustment material on the gate dielectric layer over the second vertical structure; forming a gate metal over the first and second vertical structures; removing part of the gate metal, part of the two layers of work function adjustment materials and part of the one layer of work function adjustment material, thereby exposing the second source/drain region of each of the first and second vertical structures; and forming a second barrier layer, which is separated from the first barrier layer, over the exposed second source/drain region of each of the first and second vertical structures.
