Compact Modeling of Tunneling Breakdown in PN Junctions for Computer-Aided ESD Design (CAD for ESD)

Subramanian Y., Darling R.B., University of Washington, US

This paper presents compact, physically-based electrothermal models for direct as well as indirect bandgap tunneling processes in pn-junctions for use in network simulators (e.g. Saber or VHDL-A). The model for indirect tunneling has been validated [...]

Physical Modeling of MEMS Cantilever Beams and the Measurement of Stiction Force

Lam T., Darling R.B., University of Washington, US

A finite element model is combined with experimental data to extract the stiction force in MEMS cantilever beams. The model predicts cantilever behaviors both before and after snap-down has occurred. Experimental measurements of cantilevers have [...]

Compact Modeling of Avalanche Breakdown in pn-Junctions for Computer-Aided ESD Design (CAD for ESD)

Subramanian Y., Darling R.B., University of Washington, US

This paper presents and validates compact, physically-based electrothermal models of the avalanche process in pn junctions for use in network simulators (e.g. Saber). Self-heating effects are also included. This enables the simulation of large systems [...]

Compact Models for Smart Pixels with Smart Illumination

Subramanian Y., Azadeh M., Darling R.B., University of Washington, US

Smart Pixels with Smart Illumination (SPSI) is a recently developed technology that enables the monolithic integration of two functionalities-optical illumination and detection- into arrays of optoelectronic ‘pixels’ in a compact and robust manner. To facilitate [...]

Modeling of Focused Ion Beam Trimming of Cantilever Beams

Lam T., Darling R.B., Univeristy of Washington, US

A finite element model of the cantilever beam is implemented to include a non-uniform thickness along its length, due to focused ion beam trimming. A quasi-static, iterative approach is used to calculate the cantilever profile [...]

Compact Modeling of Bistable Electrostatic Actuators

Xu J., Darling R.B., Lauritzen P.O., University of Washington, US

A compact circuit simulation model for a bistable electrostatic cantilever actuator is presented which is appropriate for circuit and system simulation of RF MEMS switches. This simplified model captures the essential physical features of a [...]
