Abstract: Techniques and mechanisms for providing gate dielectric structures of a transistor. In an embodiment, the transistor comprises a thin channel structure which comprises one or more layers of a transition metal dichalcogenide (TMD) material. The channel structure forms two surfaces on opposite respective sides thereof, wherein the surfaces extend to each of two opposing edges of the channel structure. A composite gate dielectric structure comprises first bodies of a first dielectric material, wherein the first bodies each adjoin a different respective one of the two opposing edges, and variously extend to each of the surfaces two surfaces. The composite gate dielectric structure further comprises another body of a second dielectric material other than the first dielectric material. In another embodiment, the other body adjoins one or both of the two surfaces, and extends along one or both of the two surfaces to each of the first bodies.

Abstract: Transistor structures with monocrystalline metal chalcogenide channel materials are formed from a plurality of template regions patterned over a substrate. A crystal of metal chalcogenide may be preferentially grown from a template region and the metal chalcogenide crystals then patterned into the channel region of a transistor. The template regions may be formed by nanometer-dimensioned patterning of a metal precursor, a growth promoter, a growth inhibitor, or a defected region. A metal precursor may be a metal oxide suitable, which is chalcogenated when exposed to a chalcogen precursor at elevated temperature, for example in a chemical vapor deposition process.

Abstract: Describe is a resonator that uses anti-ferroelectric (AFE) materials in the gate of a transistor as a dielectric. The use of AFE increases the strain/stress generated in the gate of the FinFET. Along with the usual capacitive drive, which is boosted with the increased polarization, additional current drive is also achieved from the piezoelectric response generated to due to AFE material. In some embodiments, the acoustic mode of the resonator is isolated using phononic gratings all around the resonator using the metal line above and vias' to body and dummy fins on the side. As such, a Bragg reflector is formed above or below the AFE based transistor. Increased drive signal from the AFE results in larger output signal and larger bandwidth.

Abstract: Described is an ultra-dense ferroelectric memory. The memory is fabricated using a patterning method by that applies atomic layer deposition with selective dry and/or wet etch to increase memory density at a given via opening. A ferroelectric capacitor in one example comprises: a first structure (e.g., first electrode) comprising metal; a second structure (e.g., a second electrode) comprising metal; and a third structure comprising ferroelectric material, wherein the third structure is between and adjacent to the first and second structures, wherein a portion of the third structure is interdigitated with the first and second structures to increase surface area of the third structure. The increased surface area allows for higher memory density.
