One method includes forming a recessed gate/spacer structure that partially defines a spacer/gate cap recess, forming a gate cap layer in the spacer/gate cap recess, forming a gate cap protection layer on an upper surface of the gate cap layer, and removing portions of the gate cap protection layer, leaving a portion of the gate cap protection layer positioned on the upper surface of the gate cap layer. A device disclosed herein includes a gate/spacer structure positioned in a layer of insulating material, a gate cap layer positioned on the gate/spacer structure, wherein sidewalls of the gate cap layer contact the layer of insulating material, and a gate cap protection layer positioned on an upper surface of the gate cap layer, wherein the sidewalls of the gate cap protection layer also contact the layer of insulating material.
Abstract:
Approaches for improving overlay performance for an integrated circuit (IC) device are provided. Specifically, the IC device (e.g., a fin field effect transistor (FinFET)) is provided with an oxide layer and a pad layer formed over a substrate, wherein the oxide layer comprises an alignment and overlay mark, an oxide deposited in a set of openings formed through the pad layer and into the substrate, a mandrel layer deposited over the oxide material and the pad layer, and a set of fins patterned in the IC device without etching the alignment and overlay mark. With this approach, the alignment and overlay mark is provided with the fin cut (FC) layer and, therefore, avoids finification.

Abstract:
A method of forming a semiconductor structure includes forming a metal gate above a semiconductor substrate and gate spacers adjacent to the metal gate surrounded by an interlevel dielectric (ILD) layer. The gate spacers and the metal gate are recessed until a height of the metal gate is less than a height of the gate spacers. An etch stop liner is deposited above the gate spacers and the metal gate. A gate cap is deposited above the etch stop liner to form a bi-layer gate cap. A contact hole is formed in the ILD layer adjacent to the metal gate, the etch stop liner in the bi-layer gate cap prevents damage of the gate spacers during formation of the contact hole. A conductive material is deposited in the contact hole to form a contact to a source-drain region in the semiconductor substrate.
