HEMT Optimization by Advanced RSM Models

Profirescu M.D., Dima G., Govoreanu B., Mitrea O., University Politehnica of Bucharest, RO

In this paper, the optimization of heterostructure devices using the Design of Experiments concept and advanced Response Surface Models is presented. As an example, the structural optimization of a pseudomorphic Al0.2Ga0.8As/In0.2Ga0.8As/GaAs pulse doped HEMT is [...]

Optimal Shape Design of Three-Dimensional MEMS with Applications to Electrostatic Comb Drives

Ye W., Mukherjee S., Cornell University, US

A methodology for solving inverse problems in Microelectromechanical (MEM) systems is proposed in this paper. Design of variable shape electrostatic comb drives (shape motors), in order to obtain desired force profiles, is presented as an [...]

Rational RSM Models for Device Characteristics as Functions of Process Parameters

Granik Y., Moroz V., PDF Solutions, Inc., US

Conventional polynomial Response Surface Methodology (RSM) fails to provide oscillation-free analytical models for some device data with singularity like subthreshold slope vs threshold adjustment dose, poly gate length vs stepper defocus, etc. New type of [...]
