Work Experience

Princeton University - Institute of Science & Technology of Materials

Princeton, NJ

Visiting Research Collaborator Feb. 2009 - Current

. Lead research efforts by designing novel microelectomechanical systems

(MEMS) structures, improving photolithography techniques, and

fabricating deliverable products for Department of Defense contracts.

. Train new users on state-of-the-art microfabrication tools including

evaporation systems, plasma etchers, contact aligners, back-end wafer

packaging systems, and metrology instruments.

. Research new processes to solve problems and establish reliable

workflows:

o Photolithography - improve thick metal lift-off and optimize

resolution.

o Etching - configured desired selectivity and vertical slope on

semiconductors, dielectrics, and metals.

o Packaging - set up processes for flip-chip bonding, wafer dicing,

and wire bonding

. Create user manuals for back-end packaging equipment for operation and

maintenance.

. Execute monthly calibrations for SiO2 and SixNy deposition and etch

systems.

K Lab Corporation Hillsborough, NJ
