PROFESSIONAL COATING EXPERIENCE  Metal organic chemical vapor deposition (MOCVD): Deposited IrO2 nanorod by controlling different substrate temperature and precursor concentration. Furthermore, our team invented a 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 higher oxygen vacancies to make sensor more sensitivity and good electrical properties. This successful achievements were showed on on my master thesis and were been published 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 to design 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 SOFTWARE/GRAPHIC DESIGN TOOLS SolidWorks, ProE, MINITAB, MATLAB, Macleod, TFCalc, SEM, ESCA, TEM, UV spectrometer, XRD, Raman spectrometer

Wafer Level Optics (WLO) 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 canâ&#x20AC;&#x2122;t expand quickly to the worldâ&#x20AC;&#x2122;s market. So we need to think about a better solution to solve the mentioned problems.

Quartz crystal microbalance sensor based on partially reduced IrO2 S.K. Pei a, C.J. Liu a,*, Y.S. Huang b, D.S. Tsai a a Department of Chemical Engineering, National Taiwan University of Science and Technology b Department of Electronic Engineering, National Taiwan University of Science and Technology 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.

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.

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.
