Abstract:
The current disclosure provides a semiconductor fabrication method that defines the height of gate structures at the formation of the gate structure. A gate line-end region is formed by removing a portion of a gate structure. A resulted recess is filled with a dielectric material is chosen to have a material property suitable for a later contact formation process of forming a metal contact. A metal contact structure is formed through the recess filling dielectric layer to connect to a gate structure and/or a source/drain region.

Claim (Index 1):
A method, comprising:\n providing a wafer including a substrate, a plurality of gate structures over the substrate, and a first dielectric layer over the substrate, the first dielectric layer being adjacent to and at substantially a same level as the plurality of gate structures and the plurality of gate structures having a first height; forming a mask layer over the wafer, the mask layer including a first aperture exposing at least a portion of a gate structure of the plurality of gate structures; forming a recess by removing the portion of the gate structure, the recess being laterally surrounded by the first dielectric layer; forming a second dielectric layer over the first dielectric layer, the second dielectric layer filling the recess; and after the forming the second dielectric layer filling the recess, forming a conductive contact structure extending from an upper surface of the second dielectric layer downward beyond an upper surface of the first dielectric layer.
