Modeling of SiC Lateral Resonant Devices Over a Broad Temperature Range

DeAnna R.G., Roy S., Zorman C.A., Mehregany M., US Army Research Laboratory, US

Finite-element analysis (FEA) modal results of 3C-SiC lateral resonant devices anchored to a Si substrate are presented as resonant frequency versus temperature. The suspended elements are etched from a 2 mm, 3C-SiC film grown at [...]

Analytical Modeling of Cross-Axis Coupling in Micromechanical Springs

Iyer S., Zhou Y., Mukherjee T., Carnegie Mellon University, US

Analytical models to describe coupling between different directions of motion are derived using energy methods and verified for the U-spring, crab-leg spring and the serpentine spring. Finite element analyses (FEA) are done for a range [...]

Modeling and Design Optimization of a CMOS Compatible MEMS

Latorre L., Bertrand Y., Hazard P., Pressecq F., Nouet P., LIRMM-CNRS, FR

Silicon etching at low temperature offers the possibility of manufacturing monolithic sensors with associated electronics. For a given technology, the so-called FSBM, we have established a set of relations to describe the mechanical behavior of [...]

Measuring and Characterizing Sub-Micron Short Channel LDD MOSFETs

Liu P.C., Lin H., Nanyang Technological University, SG

An efficient model for accurate predication of the I-V characteristics of submicrometer LDD MOSFET is described in this paper. The model is based on n-th power law model[1] by treating the effective electrical channel length [...]

Structure Optimization of 140 GHz Pulsed-Mode IMPATT Diode

Zemliak A., Celaya C., Garcia R., Puebla Autonomous University, MX
