Summary

• Research Engineer/Scientist – Semiconductor/Solar Materials

• Entrepreneur and Manager – R&D. US citizen

• Innovator with dozens of patents issued, new products launched

Experience

SunEdison, StPeters, MO -Fortune 1000 Company, Semiconductor/Solar Industry 2013 - 2015

Senior Research Engineer Responsibilities: Si wafer process development

Accomplishments:

• Developed novel manufacturing processes for silicon-on-insulator and solar wafers, being

patented.

• Developed 300mm SOI wafer process for RF applications (handhelds and cell phones).

Resulting wafers far exceed existing products in RF performance (2nd harmonic

suppression). Company became first on market with 300mm SOI for RF product

Redwood Renewables, Corte Madeira, CA 2012 - 2013

Consultant Responsibilities: Develop antireflective coatings

Accomplishments:

• invented surface modification to form moth eye pattern on glass; resulting glass has

extremely low reflectivity; this antireflective coating is used in advanced solar cells

Nanocoating Plasma Systems, Fremont, CA 2011 - now

Consultant Responsibilities: Develop atmospheric plasma coating tool

Accomplishments:

• troubleshoot problems like clogging of 10-nm nanopowder in plasma torch feeder, etc.

Corning, Inc., Corning, NY 2008 - 2013

Research Associate Responsibilities: Develop solar related Glass products

Accomplishments:

• contributed to many photovoltaic projects – on silicon tandem solar cell (collaborative

project with Oerlikon), on superstrate and substrate glass for CdTe and CIGS cells, etc.

• solved problems of single crystal silicon layer transfer onto glass by modifying Smart-Cut

process. Silicon-on-glass substrate can be used to make, say, computer integrated with

display on a single sheet.

• suggested way as to add self-cleaning, fingerprint-repelling, and self-disinfecting property to

face surfaces of handheld devices – potentially can be used in all next generations handheld

devices.

• critically contributed to process of making solar silicon wafers directly from molten silicon

(kerf-free) – cost of silicon substrates for solar cells can be significantly reduced

MEC Tech, Toms River, NJ 2005 - 2008

Scientist Responsibilities: Lead development of new products

Accomplishments:

• developed process for making single crystalline silicon focus rings for plasma etching

equipment – significantly lowered cost

• chemical polishing of crystalline silicon thus enabling complicated shapes to be polished.

Results in better quality showerheads and focus rings for plasma equipment

Silicon Wafer Technologies, Newark, NJ 2000 - 2005

Co-Founder Responsibilities: Run high tech startup

Accomplishments:

• covered silicon-on-insulator (SOI) process with numerical patents

• fabricated prototypes of ultrathin SOI wafers useful for manufacturing of next generation

chips

Education

• PhD - Material Science, Physics, Moscow Technology University - Moscow, Russia 1988

• MSEE - Semiconductors, Moscow Institute of Electronic Technology - Moscow, Russia 1980

Technical Skills

• Thin film: PECVD, CVD, PVD, atmospheric plasma deposition, including TCO

• Semiconductor Processing: ion implantation, epitaxy, plasma and wet etch, cleaning, etc.

• Fabrication process of polycrystalline silicon solar cells

• Fabrication process of tandem (poly+amorphous) silicon film solar cells

• Superstrate and substrate glass for CdTe and CIGS solar cells

• Diffusion through thin films for encapsulation of silicon tandem solar cells, CdTe and CIGS

cells

• Glass, glass-ceramics and ceramics process technologies

• Modification of glass surface to add new functionalities:

• Lower reflectivity

• Lower Glare

• Reject fingerprints, anti-smudge

• Self-cleaning (superhydrophilic and photocatalytic)

• Self-disinfecting

• Scratch resistance

• Superhydrophobic or superhydrophilic (non-fogging)
