摘要:
A method of forming contacts over active gates is provided. Embodiments include forming first and second gate structures over a portion of a fin; forming a first and second RSD in a portion of the fin between the first gate structures and between the first and the second gate structure, respectively; forming TS structures over the first and second RSD; forming a first cap layer over the first and second gate structures or over the TS structures; forming a metal oxide liner over the substrate, trenches formed; filling the trenches with a second cap layer; forming an ILD layer over the substrate; forming a CA through a first portion of the ILD and metal oxide layer down to the TS structures over the second RSD; and forming a CB through a second portion of the ILD and metal oxide layer down to the first gate structures.
