Fabrication of Field-Sequential Color Display Using Predesigned Ferroelectric Liquid Crystals

Liu C-Y, Liu J-H, Zhange Y-S, Liu C-Y, Liu J-H, UC-Berkeley, US

A novel series of low transition temperature and fast response chiral Smectic C (SmC*) liquid crystals was designed and synthesized. Phase transition behaviors and electro-optical properties of the synthesized compounds were investigated and compared. Ferroelectric [...]

BSIM4 and BSIM Multi-Gate Progress

Dunga M.V., Lin C.H., Xi X., Chen S., Lu D.D., Niknejad A.M., Hu C., UC-Berkeley, US

Compact models form an integral part of any circuit design environment, ranging from analog and digital design to mixed-signal design worlds. The models need to be developed and improved in parallel with technology advancements to [...]

MEMS Process Characterization with an on-Chip Device

Garmire D., Choo H., Muller R.S., Govindjee S., Demmel J., UC-Berkeley, US

We have developed a CMOS-compatible, compact device and a simple procedure for measuring three important fabrication characteristics of planar-processed microelectromechanical (MEMS) structures: in-plane over- or under-cut, Young’s Modulus, and comb-drive forces in a MEMS process. [...]

On the Vibrations of a MEMS Gyroscope

Davis W.O., Pisano A.P., UC-Berkeley, US

In this paper, the dynamics of a dual-axis MEMS gyroscope are examined. The model for the device is based on a non-linear rod theory developed by A. E. Green, P. M. Naghdi and several co-workers. [...]

Nodal Analysis for MEMS Design Using SUGAR v0.5

Zhou N., Clark J.V., Pister K.S.J., UC-Berkeley, US

This paper presents the development of a simulation program (SUGAR) for planar MEMS devices. The approach is based on nodal analysis to solve coupled nonlinear differential equations. The current version SUGAR vO.5 can perform DC, [...]
