The embedded resistors have a pillar structure, i.e., they have a height that is greater than their width, thus they occupy less real estate as compared with conventional planar resistors that are typically employed in BEOL technology.

Abstract: After forming a contact opening in a dielectric material layer located over a substrate, a metal liner layer comprising a nitride of an alloy and a metal contact layer comprising the alloy that provides the metal liner layer are deposited in-situ in the contact opening by sputter deposition in a single process and without an air break. Compositions of the metal liner layer and the metal contact layer can be changed by varying gas compositions employed in the sputtering process.

The capacitor structure is formed by a single process which enables the in-situ conformal deposition of the electrode and dielectric layers of the capacitor structure. The single process includes atomic layer deposition in which a metal-containing precursor is selected to provide each of the layers of the capacitor structure. The lower electrode layer is formed by utilizing the metal-containing precursor and a first reactive gas, the high-k metal oxide dielectric layer is provided by switching the first reactive gas to a second reactive gas, and the upper electrode layer is provided by switching the second reactive gas back to the first reactive gas.

Abstract: A semiconductor structure is provided in which metal semiconductor alloy pillars are formed at least partially within the sidewall surfaces of each semiconductor fin that extends from a surface of a substrate. These pillars are fuses (i.e., FinFET fuses) that are formed at a very tight pitch dimensions. The pillars can be trimmed after forming FinFET devices. The present application provides a method for forming on-chip FinFET fuses easily by choice of the metal semiconductor alloy, the amount of pillar trim, the number of contacted pillars and to a lower design degree the height of each pillar.

The method enables the in-situ deposition of a bottom electrode layer (i.e., a metal layer), a resistive switching element (i.e., at least one metal oxide layer), and a top electrode layer (i.e., a metal nitride layer and/or a metal layer) with compositional control. Resistive random access memory devices which contain uniform layer composition enabled by the in-situ deposition of the bottom electrode layer, the resistive switching element, and the top electrode layer provide significant benefits for advanced memory technologies.

Abstract: A low resistance middle-of-line interconnect structure is formed without liner layers. A contact metal layer is deposited on source/drain regions of field-effect transistors and directly on the surfaces of trenches within a dielectric layer using plasma enhancement. Contact metal fill is subsequently provided by thermal chemical vapor deposition. The use of low-resistivity metal contact materials such as ruthenium is facilitated by the process. The process further facilitates the formation of metal silicide regions on the source/drain regions.

Abstract: A magnetic tunnel junction (MTJ) structure having faceted sidewalls is formed on a conductive landing pad that is present on a surface of an electrically conductive structure embedded in a dielectric material layer. No metal ions are re-sputtered onto the sidewalls of the MTJ structure during the patterning of the MTJ material stack that provides the MTJ structure. The absence of re-sputtered metal on the MTJ structure sidewalls reduces the risk of shorts.

Thereafter, a gate structure is formed on the vertically orientated channel region, and a second source/drain region is formed on the vertically orientated channel region.
