Publication number: 20200365585Abstract: Techniques for forming contacts comprising at least one crystal on source and drain (S/D) regions of semiconductor devices are described. Crystalline S/D contacts can be formed so as to conform to some or all of the top and side surfaces of the S/D regions. Crystalline S/D contacts of the present disclosure are formed by selectively depositing precursor on an exposed portion of one or more S/D regions. The precursor are then reacted in situ on the exposed portion of the S/D region. This reaction forms the conductive, crystalline S/D contact that conforms to the surface of the S/D regions.Type: ApplicationFiled: September 26, 2017Publication date: November 19, 2020Applicant: Intel CorporationInventors: Karthik JAMBUNATHAN, Scott J.

Patent number: 10818793Abstract: Techniques are disclosed for forming high mobility NMOS fin-based transistors having an indium-rich channel region electrically isolated from the sub-fin by an aluminum-containing layer. The aluminum aluminum-containing layer may be provisioned within an indium-containing layer that includes the indium-rich channel region, or may be provisioned between the indium-containing layer and the sub-fin. The indium concentration of the indium-containing layer may be graded from an indium-poor concentration near the aluminum-containing barrier layer to an indium-rich concentration at the indium-rich channel layer. The indium-rich channel layer is at or otherwise proximate to the top of the fin, according to some example embodiments. The grading can be intentional and/or due to the effect of reorganization of atoms at the interface of indium-rich channel layer and the aluminum-containing barrier layer. Numerous variations and embodiments will be appreciated in light of this disclosure.Type: GrantFiled: February 23, 2019Date of Patent: October 27, 2020Assignee: Intel CorporationInventors: Chandra S.

Publication number: 20200321439Abstract: Monolithic FETs including a fin of a first III-V semiconductor material offering high carrier mobility is clad with a second III-V semiconductor material having a wider bandgap. The wider bandgap cladding may advantageously reduce band-to-band tunneling (BTBT) leakage current while transistor is in an off-state while the lower bandgap core material may advantageously provide high current conduction while transistor is in an on-state. In some embodiments, a InGaAs cladding material richer in Ga is grown over an InGaAs core material richer in In. In some embodiments, the semiconductor cladding is a few nanometers thick layer epitaxially grown on surfaces of the semiconductor core. The cladded fin may be further integrated into a gate-last finFET fabrication process. Other embodiments may be described and/or claimed.Type: ApplicationFiled: June 17, 2016Publication date: October 8, 2020Applicant: Intel CorporationInventors: Sean T. Ma, Chandra S.

Publication number: 20200303373Abstract: Techniques are disclosed for using compositionally different contact materials for p-type and n-type source/drain regions on a common substrate. The different contact materials may be within a common source/drain contact trench, or in type-dedicated trenches. A given contact trench may span one or more fins and include one or more source/drain regions on which a corresponding contact structure is to be made. In an embodiment, an isolation structure between p-type and n-type fins is selective to the trench etch and therefore remains intact within the trench after the target source/drain regions have been exposed. In such cases, the isolation structure physically separates n-type source/drain regions from p-type source/drain regions. The contact structures on the different type source/drain regions may be shorted proximate the top of the isolation structure. Numerous material systems can be used for the channel and source/drain regions, including germanium, group III-V materials, and 2-D materials.Type: ApplicationFiled: December 28, 2017Publication date: September 24, 2020Applicant: INTEL CORPORATIONInventors: Glenn A.

Publication number: 20200286996Abstract: Techniques are disclosed for deuterium-based passivation of non-planar transistor interfaces. In some cases, the techniques can include annealing an integrated circuit structure including the transistor in a range of temperatures, pressures, and times in an atmosphere that includes deuterium. In some instances, the anneal process may be performed at pressures of up to 50 atmospheres to increase the amount of deuterium that penetrates the integrated circuit structure and reaches the interfaces to be passivated. Interfaces to be passivated may include, for example, an interface between the transistor conductive channel and bordering transistor gate dielectric and/or an interface between sub-channel semiconductor and bordering shallow trench isolation oxides.Type: ApplicationFiled: May 18, 2020Publication date: September 10, 2020Applicant: INTEL CORPORATIONInventors: PRASHANT MAJHI, GLENN A.

Publication number: 20200287024Abstract: Transistors having a plurality of channel semiconductor structures, such as fins, over a dielectric material. A source and drain are coupled to opposite ends of the structures and a gate stack intersects the plurality of structures between the source and drain. Lateral epitaxial overgrowth (LEO) may be employed to form a super-lattice of a desired periodicity from a sidewall of a fin template structure that is within a trench and extends from the dielectric material. Following LEO, the super-lattice structure may be planarized with surrounding dielectric material to expose a top of the super-lattice layers. Alternating ones of the super-lattice layers may then be selectively etched away, with the retained layers of the super-lattice then laterally separated from each other by a distance that is a function of the super-lattice periodicity. A gate dielectric and a gate electrode may be formed over the retained super-lattice layers for a channel of a transistor.Type: ApplicationFiled: December 27, 2017Publication date: September 10, 2020Applicant: INTEL CORPORATIONInventors: Gilbert Dewey, Sean T.

Publication number: 20200287011Abstract: Techniques are disclosed for forming transistor devices having reduced parasitic contact resistance relative to conventional devices. The techniques can be implemented, for example, using a standard contact stack such as a series of metals on, for example, silicon or silicon germanium (SiGe) source/drain regions. In accordance with one example such embodiment, an intermediate boron doped germanium layer is provided between the source/drain and contact metals to significantly reduce contact resistance. Numerous transistor configurations and suitable fabrication processes will be apparent in light of this disclosure, including both planar and non-planar transistor structures (e.g., FinFETs), as well as strained and unstrained channel structures. Graded buffering can be used to reduce misfit dislocation. The techniques are particularly well-suited for implementing p-type devices, but can be used for n-type devices if so desired.Type: ApplicationFiled: May 22, 2020Publication date: September 10, 2020Applicant: INTEL CORPORATIONInventors: Glenn A.

Patent number: 10770593Abstract: Techniques are disclosed for forming a beaded fin transistor. As will be apparent in light of this disclosure, a transistor including a beaded fin configuration may be formed by starting with a multilayer finned structure, and then selectively etching one or more of the layers to form at least one necked (or relatively narrower) portion, thereby forming a beaded fin structure. The beaded fin transistor configuration has improved gate control over a finned transistor configuration having the same top down area or footprint, because the necked/narrower portions increase gate surface area as compared to a non-necked finned structure, such as finned structures used in finFET devices. Further, because the beaded fin structure remains intact (e.g., as compared to a gate-all-around (GAA) transistor configuration where nanowires are separated from each other), the parasitic capacitance problems caused by GAA transistor configurations are mitigated or eliminated.Type: GrantFiled: April 1, 2016Date of Patent: September 8, 2020Assignee: Intel CorporationInventors: Gilbert Dewey, Tahir Ghani, Willy Rachmady, Jack T.
