PROFESSIONAL COATING EXPERIENCE
� Metal organic chemical vapor deposition (MOCVD):Deposited IrO2 nanorod by controlling different substrate temperature and precursor concentration. Furthermore, our team inventeda useful technique to reduced IrO2
become Ir/IrO2 co-existed or Ir existed independently on quartz crystal microbalance (the evidence by XRD, XPS investigation), Ir/IrO2 or Ir nanorod surface had higheroxygen vacancies to make sensor more sensitivity and good electrical properties. This successful achievements were showed on on my master thesis and were beenpublished at Singapore conference of Nanyang Technological University.� Ion beam plasma vacuum deposition: Deposited metal oxide, for example, TiO2/SiO2 multilayer on anti-reflection (AR) coating and infrared light cut filter. Controlled parameters such as ion source energy, crucible rotated rate, source evaporated rate and substrate temperature (dorm substrate) to get higher density of optical thin film. It was used on plastic lens coating which physical parameters such as transmittance and reflectance were detected by UV-vis spectrometer. In addition, use Optical thin film simulation of Macleod & TFCalc todesign color filter coating layers mixing with high and low refractive thin film to meet customer spec, for example, IR-cut_TiO2/SiO2_42 layers met Tave% > 95% at wavelength 420nm~680nm and Tave% < 2% at wavelength 700nm~1200nm ; AR_TiO2(Ta2O5)/SiO2_6~8 layers met Tave% > 99% at wavelength 420nm~680nm. � In-line sputtering (multiple cathode):The system coated Cu/SUS EMI sputtering to avoid electromagnetic disturbance, plastic decoration, light guide plate coated CrN used in dashboard, solar cell AR coating.� Reactive magnetron sputtering deposition: Sputtering TiO2 as seed layer on quartz for gas sensor, AlCu, TiN, Si3N4, WSix and SiO2 to produce poly/metal or polysilicon/metal layers or Pt-Ir-Ni 0.8~1.1um as protective layers on molding jig to mold optical glass….etc� Aerosol spray pyrolysis: Build system by myself, invented rapid, low cost, and non-vacuum nebulization system, combined the system with hydrothermal system to manufacture many kinds of transition metal oxide (TiO2, RuO2, IrO2, ZnO…), ZnO nanorod had been used on NO2 gas sensing, which successful achievements had been published on journal papers� Sol-gel method: combined it with my invented aerosol spray pyrolysis system to do dye-sensitized solar cell device (DSSC, SnO2:F/TiO2(by spray)/N3-dye (by sol-gel) ), this device had 3% ~ 4% solar efficiency

In today modern society, people always love to take a picture outside with high resolution image camera device in order to satisfy their desire. Based on the condition, there are some kind of new
technologies performing now. The name is called wafer level optics (WLO). The camera modules of the portable electronic devices have become smaller and smaller in size. Accordingly, it is required
that optical elements (e.g., a light blocking plate) used in the camera module have a smaller size/volume.
Due to WLO expensive cost, and complex manufacturing process. These reasons cause WLO can’t expand quickly to the world’s market. So we need to think about a better solution to solve the
mentioned problems.

Nanostructured IrO2 crystals are grown on a gold-coated quartz substrate by metal organic chemical vapor deposition (MOCVD).
The resultant quartz crystal microbalance (QCM) sensors show good gas sensitivities towards carboxylic acid at the ppm level.
When the oxide is heated at 450℃~600℃in high vaccum, the IrO2 is partially reduced to Ir/IrO2 by thermal decomposition.
The Ir/IrO2 sensor shows higher gas sensitivity as compared to the IrO2 sensor, but with lower sensor reversibility.
Further improvement of the sensor reversibility can be achieved by growing the IrO2 crystals onto a thin Ti layer deposited on the Au electrode,
followed by the same reduction treatment.
The composition and the morphology of the IrO2 surface before and after thermal reduction are investigated by X-ray diffraction (XRD),
X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, and scanning electron microscopy (SEM).
The mechanism of improvements in sensitivity and reversibility will also be discussed.

This research used AT-cut 10MHz quartz covered by two side of gold electrode which was 0.38 cm diameter and MOCVD method, syatem as shown in Fig. to deposit IrO2 nano rod onto gold electrode surface.
Precursor coated material was (MeCp)Ir(COD) under 110℃ to mixed well and spray onto the QCM substrate. Substrate temperature(Ts) was controlled in 350℃ and environmental gas flow was 80 sccm under the
maintained chamber pressure for 20 mbar. After deposited IrO2 for 1 hr, we opened turbo pump to further reached in high vacccum pressure at 5*10-5mbar and controlled Ts from 350℃ up to the range
of 450℃ ~ 600℃ for 30 to 90 minutes. Finally, compared the above sensor result before and after reduction.
When did upon work of manufactured IrO2-OCM electrode, we used VOC sensing system, to detect sensor signal by injected Propanic acid compound to volatile acid gas adsorption
on IrO2-QCM surface. After a while when adsorped signal frequency was stable and was no variation increased, then controlled nitrogen gas by MFC flow meter to 100 sccm at 25℃ and desorption acid molecule
from IrO2 surface.
Figure shows that XPS analyze IrO2 composition before and after reduction at different reduction temperature. When the
reduction temperature headed up to 450℃which composition consisted of IrO2/IrO3/Ir(OH)x was as the same as no reduction, as shown in
Fig (a)(b), but fewer binding peak of Ir 4f7/2
and Ir4f5/2
at 450℃ than no reduction. It was probably the reason that no increased variation
frequency but decreased reversibility. When headed up to 550℃, the phase transformed to Ir/IrO2 and its higherΔf (~270Hz) and Re%(~98%)
contributed to the C=O or –OH easily to bind with Ir vacancy side by physical adsorption to form the byproduct IrO2. After pump in N2 gas to
desorption, reversibility will easily to recover. When headed up to 600℃, the phase transformed to Ir/Ir4+-Oads and Δf further up to 320Hz .
However reversibility goes down to 32%. The reason for that contributed to the C=O or –OH much strongly binding on metal Ir but hardly to
leave from Ir4+-Oads, Oads may be hydroxide from the air.

SEM top view and cross sectional view under the different reduction time and reduction temperature.
The surface morphology before reduction shows incomplete-nanotube and nano blade as the same as by controlling lower
reduction temperature 450℃. At higher reduction temperature like 550℃, nanorod were aggregated to form the flower shape
which existed much more adsoption area that caused higher variarition frequency. Nanorode length which was easily increased by
higher reduction temperature, but there is no evidence to say the length could affect the sensor quality.

Iridium dioxide can be produced by MOCVD and partially reduced at different reduction temperature and reduction time.
We proved the adsorption frequency and revesibility coming from oxgen vacancy on Iridium metal such as Ir/Ir4+ vacancy,
Ir4+ vacancy or Ir vacancy. We also improved reversibility by coated Ti seed layer under IrO2 nanorod. It was very efficiency
way that could be used in all kind of metal oxide gas sensor.
X-ray diffraction pattern shows that only IrO2 peak existed in the structure. After the reduction for 450~550℃, the main IrO2 (101) was partial reduced to Ir/IrO2 phase.

Statement of Purpose
My name is SHAO-KAI PEI. I was greatly inspired by media-lab speakers from Ted.com and opening course for turning their innovative ideasinto actual inventions. Hence I have been applying my enthusiasm for inventions ever since. I have been focusing on improving theOEM/ODM electronic manufacturing as well as the R&D strength with Foxconn Technology Group, the company I am working now, and Ihave filed 105 U.S. patents with 13 patents issued with the company. In addition, I had managerial experience over product design andmanufacturing for clients such as Apple, Nokia, HTC, and Nintendo.
During the past 2 year of the world’s economic crisis, we met a lot of factory problems not only a labor strike on salary but also the productsprofit going down. Overseeing the obstacles and failures Foxconn encountered in the past, I believe high profit products should be in what thecompany gear for. Apple Inc. is an excellent example benefiting from highly attractive product lines. Hence I will be studying in developing onhighly desirable products with durable hardware, software and the industrial surface design.
In the past six years, I also learn lots of research skills at Foxconnand VIS semiconductor company on studying thin film design andmanufacturing including inorganic film, organic film or optical film used on sensor, solar cell, semiconductor, camera module, optical device orplastic/glass decoration. I was familar with several deposition systems at the same time. Previously, when I was a 1st year graduated student, Iinvented a new kind of spray pyrolysis system which used a few solvent to do thesame thing as market spray system. My invented-system onlycost 300 USD dollars was cheaper than 5,000 USD market system. Finally, I connected my system with hydrothermal system to deposit wellstable nanorod. The achievements had already been published in the journaland national conference papers. Based on this system, it alsohelped many junior students in the laboratory to graduate soon. It made me feel sofulfillment and happy for helping people finish on theirworks. In my 2nd year, Professor asked me doing the most important National Science Council project with other laboratory students. Undertime restriction, I figured out using MOCVD to deposit IrO2-Oxygen vacancy nanorod under high temperature annealing treatment on QCMsensor and discover higher sensitive signals on sensing Propanic/Amino acid than traditional IrO2 sensor. It will probably improve PH meterfunction in the future. Therefore, when I graduated from school, I got 89(A) score ofmy oral thesis.
I believe that my professional coating experience can help Professorto develop new kind of materials both in creative ways and in cost-downsolution combined with some coating treatments of high-quality thin film deposition. I am certain that study will help me to fulfill of myresearch goals of inventing under profit into the world’s market. Hope you can take my application into consideration and give me a chance torealize my dream to become outstanding inventor in the world.
