SEMICONDUCTOR DEVICE AND METHOD FOR FORMING THE SAME - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17724434 Titled 'SEMICONDUCTOR DEVICE AND METHOD FOR FORMING THE SAME'
Simplified Explanation
The abstract describes a method for fabricating a device using carbon nanotubes (CNTs). The process involves several steps, including depositing a dielectric layer on a substrate, growing a CNT on top of the dielectric layer, creating a dummy gate structure on the CNT, adding gate spacers on the sides of the dummy gate structure, forming source/drain epitaxy structures on either side of the dummy gate structure and in contact with the CNT, replacing the dummy gate structure with a metal gate structure, and finally, creating source/drain contacts on the source/drain epitaxy structures.
Original Abstract Submitted
A method includes forming a dielectric layer over a substrate; forming a carbon nanotube (CNT) over the dielectric layer; forming a dummy gate structure over the CNT; forming gate spacers on opposite sidewalls of the dummy gate structure; forming source/drain epitaxy structures on opposite sides of the dummy gate structure and in contact with opposite sidewalls of the CNT; replacing the dummy gate structure with a metal gate structure; and forming source/drain contacts over the source/drain epitaxy structures, respectively.
