Abstract
Embodiments of present invention provide a semiconductor structure. The semiconductor structure includes a first transistor having a first source/drain region and a second transistor having a second source/drain region; a first source/drain contact around the first source/drain region and a second source/drain contact around the second source/drain region; and a dielectric filler between the first source/drain contact and the second source/drain contact, wherein the dielectric filler has a first portion on top of a second portion, sidewalls of the first portion of the dielectric filler being linearly tapered to result in a width at a top of the first portion being larger than a width at a bottom of the first portion. A method of forming the same is also provided.
