Short-channel effect immunity and current capability of sub-0.1-micron MOSFET's using a recessed channel

P.-H. Bricout, Emmanuel Dubois

Sub-0.1 micron planar and gate recessed MOSFET's are investigated using both drift-diffusion and Monte Carlo simulations. In nonplanar devices, the influence of the gate corner explains that the threshold voltage roll-off can be almost suppressed. A steeper subthreshold slope (low swing) is…

Magnon band structure of periodic composites

Jerome O. Vasseur, L. Dobrzynski, Bahram Djafari-Rouhani, H. Puszkarski

We calculate the spin-wave spectra of two-dimensional composite materials consisting of periodic square arrays of parallel cylinders made of a ferromagnetic material embedded in a ferromagnetic background. Each material is described by its spontaneous magnetization MS and exchange constant A. An…

Coplanar waveguides on dielectric membranes micromachined on GaAs substrate

Patrice Salzenstein, Olivier Dupuis, Mohamed Helal, Eric Lheurette, Olivier Vanbésien, Patrick Mounaix, Didier Lippens

GaAs micromachining technology was used for fabricating coplanar transmission lines on Si3N4 and polyimide membranes deposited on GaAs substrates. On-wafer measurements of scattering parameters up to 75 GHz for several line configurations show a constant phase velocity of 2.9E8 m/s and a…

High performance InP-based heterostructure barrier varactors in single and stack configuration

Eric Lheurette, Patrick Mounaix, Patrice Salzenstein, Francis Mollot, Didier Lippens

Single (SHBV) and dual (DHBV) heterostructure barrier varactors with AlAs/In0.52Al0.48As bolocking conductionlayers have been fabricated and characterized. The devices, whose electrical properties scale with layer complexity, exhibit, for a DHBV scheme, leakage currents as low as 10 A/cm² at 12V, a…

Liaison Opto-Hyperfréquence

C. Sion, Ian Cayrefourcq, Vincent Magnin

Outre la largeur de bande instantanée, une des caractéristiques principales des antennes réseaux large bande est la couverture spatiale. Cette dernière est définie par notre habilité à orienter le faisceau émergeant de l’antenne et donc à notre aptitude à synthétiser des lois de retards. La…
