    Abstract: Methods of fabricating fin structures having exposed upper fin portions with a uniform exposure height are disclosed herein. The fabrication methods include providing a substrate with plurality of fins and a dielectric material disposed between and over the plurality of fins, planarizing the dielectric material and the plurality of fins, and uniformly recessing the dielectric material to a pre-selected depth below upper surfaces of the plurality of fins to expose upper fin portions. The exposed upper fin portions, as a result of uniformly recessing the dielectric material, have a uniform exposure height above the recessed dielectric material. A protective film may be provided over the recessed dielectric material and exposed upper fin portions to preserve the uniform exposure height of the upper fin portions. The uniform exposure height of the exposed upper fin portions facilitates subsequent formation of one or more circuit structures above the substrate.

    Abstract: One method disclosed includes, among other things, forming a gate structure above an active region of a semiconductor substrate, wherein a first portion of the gate structure is positioned above the active region and second portions of the gate structure are positioned above an isolation region formed in the substrate, forming a sidewall spacer adjacent opposite sides of the first portion of the gate structure so as to define first and second continuous epi formation trenches comprised of the spacer that extend for less than the axial length of the gate structure, and forming an epi semiconductor material on the active region within each of the first and second continuous epi formation trenches.

    Abstract: Aspects of the present invention relate to approaches for forming a narrow source-drain contact in a semiconductor device. A contact trench can be etched to a source-drain region of the semiconductor device. A titanium liner can be deposited in this contact trench such that it covers substantially an entirety of the bottom and walls of the contact trench. An x-metal layer can be deposited over the titanium liner on the bottom of the contact trench. A titanium nitride liner can then be formed on the walls of the contact trench. The x-metal layer prevents the nitriding of the titanium liner on the bottom of the contact trench during the formation of the nitride liner.

    Abstract: Structures for air-gap spacers in a field-effect transistor and methods for forming air-gap spacers in a field-effect transistor. A gate structure is formed on a top surface of a semiconductor body. A dielectric spacer is formed adjacent to a vertical sidewall of the gate structure. A semiconductor layer is formed on the top surface of the semiconductor body. The semiconductor layer is arranged relative to the vertical sidewall of the gate structure such that a first section of the first dielectric spacer is located in a space between the semiconductor layer and the vertical sidewall of the gate structure. A second section of the dielectric spacer that is located above a top surface of the semiconductor layer is removed. An air-gap spacer is formed in a space from which the second section of the dielectric spacer is removed.
