Abstract: An integrated circuit containing an n-channel finFET and a p-channel finFET is formed by forming a first polarity fin epitaxial layer for a first polarity finFET, and subsequently forming a hard mask which exposes an area for a second, opposite, polarity fin epitaxial layer for a second polarity finFET. The second polarity fin epitaxial layer is formed in the area exposed by the hard mask. A fin mask defines the first polarity fin and second polarity fin areas, and a subsequent fin etch forms the respective fins. A layer of isolation dielectric material is formed over the substrate and fins. The layer of isolation dielectric material is planarized down to the fins. The layer of isolation dielectric material is recessed so that the fins extend at least 10 nanometers above the layer of isolation dielectric material. Gate dielectric layers and gates are formed over the fins.

Abstract: The dominant frequency of a solidly mounted resonator (100/280/300/400) is substantially increased by reducing the thickness of each layer of each Bragg acoustic reflector (112/160/224/274) to have a thickness than is substantially equal to one-quarter of the wavelength of a frequency that is a higher harmonic resonant frequency of the fundamental resonant frequency of the solidly mounted resonator (100/280/300/400).

Abstract: An integrated circuit containing an n-channel finFET and a p-channel finFET has a dielectric layer over a silicon substrate. The fins of the finFETs have semiconductor materials with higher mobilities than silicon. A fin of the n-channel finFET is on a first silicon-germanium buffer in a first trench through the dielectric layer on the substrate. A fin of the p-channel finFET is on a second silicon-germanium buffer in a second trench through the dielectric layer on the substrate. The fins extend at least 10 nanometers above the dielectric layer. The fins are formed by epitaxial growth on the silicon-germanium buffers in the trenches in the dielectric layer, followed by CMP planarization down to the dielectric layer. The dielectric layer is recessed to expose the fins. The fins may be formed concurrently or separately.

Abstract: An integrated silicon and III-N semiconductor device may be formed by growing III-N semiconductor material on a first silicon substrate having a first orientation. A second silicon substrate with a second, different, orientation has a release layer between a silicon device film and a carrier wafer. The silicon device film is attached to the III-N semiconductor material while the silicon device film is connected to the carrier wafer through the release layer. The carrier wafer is subsequently removed from the silicon device film. A first plurality of components is formed in and/or on the silicon device film. A second plurality of components is formed in and/or on III-N semiconductor material in the exposed region. In an alternate process, a dielectric interlayer may be disposed between the silicon device film and the III-N semiconductor material in the integrated silicon and III-N semiconductor device.

Abstract: By controlling the concentration and size of bulk micro defects (BMD) during the manufacture of an integrated circuit slip and associated yield loss due to slip may be eliminated. A process for eliminating slip that is customized to an integrated circuit (IC) manufacturing flow is disclosed. The process is adapted to the oxygen content of the starting material and to the thermal budget of an IC manufacturing flow and generates a sufficient concentration of BMDs of a size that is optimized to getter microcracks thereby eliminating slip. Slip is eliminated in unpatterned wafers and in wafers containing shallow trench isolation and deep trench isolation using a BMD nucleation anneal and a BMD growth anneal.

Abstract: A method of semiconductor fabrication includes providing an unpatterned lightly doped Czochralski bulk silicon substrate (LDCBS substrate) having a concentration of oxygen atoms of at least (?) 1017 atoms/cm3 with a boron doping or n-type doping concentration of between 1×1012 cm?3 and 5×1014 cm?3. Before any oxidization processing, the LDCBS substrate is annealed at a nucleating temperature between 550° C. and 760° C. for a nucleating time that nucleates the oxygen atoms in a sub-surface region of the LDCBS substrate to form oxygen precipitates therefrom. After the annealing, a surface of the LDCBS substrate or an epitaxial layer on the surface of the LDCBS substrate is initially oxidized in an oxidizing ambient at a peak temperature of between 800° C. and 925° C. for a time less than or equal (?) to 30 minutes.
