WORKING/RESEARCH EXPERIENCE

Implant/PVD/RTP Process Engineer, Micron Technology Virginia, Manassas, VA,

June 2008 - Present

. Working with shift engineers and technicians to make sure process/tool is

running normally and efficiently in the Fab; daily shift duty including

lot disposition, tool qualification, process/tool troubleshooting, etc.

. Participating in tool maintenance and troubleshooting to constantly

improve knowledge on tool/process in my working area

. Communicating and coordinating with 1st shift engineers regarding

tool/process issues, and getting involved in various projects with 1st

shift personnel

. Working short-term on 1st shift project for FDC strategy improvement in

my working area

. Actively taking training class to learn new knowledge and new skills in

the overall memory industry and in my specific working area

Research Associate, Department of Chemical & Environmental Engineering,

University of Arizona, Tucson, AZ, February 2007 - June 2008

. Used electro-coagulation and other electrochemical methods to remove

silica coming from wastewater in semiconductor industry

. Developed a new ion exchange system to remove hardness coming from

wastewater in semiconductor industry

Researcher/Prototyper, Home Cleaning RD&E, SJ Johnson & Son, Inc., Racine,

WI, August 2006 - February 2007

. Coordinated the whole process of new product development, from drafting

invention disclosure, to organizing ideation session, developing new

formulation, building prototypes, performing laboratory test,

participating in consumer placement, analyzing data, preparing reports

and presentations to convey learning, conclusions and recommendations

. Cooperated with people from different departments to design and develop a

new pilot-scale process for product improvement

Graduate Research Assistant, Department of Chemical Engineering, Kansas

State University, Manhattan, KS, August 2000 - July 2006

. Synthesized AlN-SiC alloy crystals, AlN and ScN bulk crystals and thin

films by high temperature sublimation and chemical vapor deposition; made

the process more reproducible and achieved larger-size and better-quality

crystals than previous researchers in my group

. Confirmed the high crystalline quality using various characterization

techniques such as SEM, AFM, XRD and defect-selective wet chemical

etching

. Collaborated with Department of Chemistry at KSU to synthesize

nanoparticle metal oxide catalysts by a modified sol-gel procedure;

characterized them by BET and XRD, and proved the large surface area,

small particle size and favorable pore structures of nanoparticles in

comparison to microparticles

. Evaluated and compared the performance of nanoparticle metal oxide

catalysts and corresponding microparticle catalysts for the oxidation of

methanol in a fixed-bed reactor; demonstrated nanoparticle catalysts had

higher activity and stability than microparticles by achieving the same

conversion at temperatures approximately 100 C lower

Researcher, Key Laboratory of Chemical Reaction Engineering, East China

University of Science and Technology, Shanghai, China, September 1997 -

July 2000

. Modeled and simulated a multifunctional reactor - PSR (pressure swing

reactor, which combines pressure swing adsorption and chemical reaction

in a single reactor) using an advanced process modeling, simulation and

optimization software - gPROMS, to provide decision support in process

design and process operation

. Optimized the PSR process using gPROMS, and achieved a ~10% increase in

the reactant conversion

. Designed and assembled a PSR system; carried out a sample reaction to

verify the accuracy of the modeling results, which were within the 15%

error range
