In this work, a metrology was proposed to realize the distribution of fixed oxide trapped charges and grain boundary trapped states. The (continuous-wave green laser crystallization) n-channel thin-film transistors (TFTs) were forced by dc voltage stress, V(G)=V(D). The gate-to-drain capacitance, C(GD) -V(G), with varying frequency of applied small signal was developed. To probe the distribution of these defects, the difference (initial capacitance values minus stressed capacitance values) of C(GD) -V(G) with different frequencies was precisely studied.

The microscopic features of binary mixtures formed by an ionic liquid (EMI(+)TFSA(-) or EMI(+)FSA(-)) and a molecular liquid (acetonitrile or methanol) have been investigated by high-pressure infrared spectroscopy. On the basis of its responses to changes in pressure and concentration, the imidazolium C-H appears to exist at least in two different forms, i.e., isolated and associated structures. The weak band at approximately 3102 cm(-1) should be assigned to the isolated structure. CD(3)CN can be added to change the structural organization of ionic liquids. The compression of an EMI(+)TFSA(-)/CD(3)CN mixture leads to the increase in the isolated C-H band intensity. Nevertheless, the loss in intensity of the isolated structures was observed for EMI(+)FSA(-)/CD(3)CN mixtures as the pressure was elevated. In other words, the associated configuration is favored with increasing pressure by debiting the isolated form for EMI(+)FSA(-)/CD(3)CN mixtures. The stronger C-H center dot F interactions in EMI(+)FSA(-) may be one of the reasons for the remarkable differences in the pressure-dependent results of EMI(+)TFSA(-) and EMI(+)FSA(-).
Low voltage active pressure sensor based on polymer space-charge-limited transistor

Low voltage active pressure sensor is realized by vertically stacking a pressure sensitive rubber on a polymer space-charge-limited transistor. The sensor can be turned on and off by modulating the metal-grid base voltage within the range of 3 V. The output current is irrelevant to the pressure as the sensor is off. As the sensor is turned on, the output current values can be used to monitor the pressure. Reversible pressure sensing characteristics is observed below the pressure of 7.11 psi. The response time of the sensor to the pressure is as short as 22 ms. (C) 2009 American Institute of Physics. [doi:10.1063/1.3266847]

Ti/Al targets with various concentration ratios, Ti(0.75)Al(0.25), Ti(0.66)Al(0.33), Ti(0.5)Al(0.5) and Ti(0.33)Al(0.66) were used in a filtered cathodic arc ion plating system (FCAIP) to deposit the multilayer TiAlN films on Si wafer substrates and WC cermet ball grid array (BGA) cutters at various modulation wavelengths. Transmission electron microscopy (TEM), nanoindentation and BGA router were used to evaluate the characteristics of TiAlN layers and the performance of BGA cutters. TEM analysis revealed that the modulation wavelengths of deposited layers are less than 10 nm at various rotation speeds in FCAIP chamber and the crystal structure of TiAlN layer with the maximum hardness is NaCl-B1 structure using the Ti(0.5)Al(0.5) target The maximum hardness of multiple TiAlN layers measured by nanoindentation was 43 GPa,while the TiAlN monolayer exhibited the maximum hardness of 30 GPa in the same chamber. The TiAlN-coated BGA cutter deposited at the optimized condition exhibited a twice longer life and a higher machining speed in comparison with the conventional cutter. (C) 2009 Elsevier B.V.

Improvement of the performance of ZnO TFTs by low-temperature supercritical fluid technology treatment

in this paper, the supercritical CO(2) (SCCO(2)) fluid technology is successfully applied to improve the electrical characteristics of sputtered ZnO TFTs at low temperature (150 degrees C). After the treatment of SCCO(2) fluids mixed with water, the ZnO TFT exhibited superior transfer characteristics and lower threshold voltage. According to X-ray photoelectron spectroscopy (XPS) analyses, the improvements were attributed to the increase of binding energies of Zn-O bonds, hydrogen-related donors and the reduction of traps at the grain boundaries in ZnO thin films. In addition, the crystalline quality and microstructure of ZnO thin films were also investigated by using X-ray diffraction (XRD) and transmission electron microscopy (TEM). The transmittance of the ZnO film was measured by an N&K analyzer 1280 (N&K Technology, Inc.), which is a new type of thin-film measurement system. (C) 2009 Elsevier B.V. All rights reserved.

看著戲院外的手繪電影海報選電影看，是很多四、五年級生的共同回憶，栩栩如生的林青霞以及秦漢巨幅海報，讓人驚嘆不已。時間拉回現在，手繪海報早已不見蹤跡，印刷精美的海報處處可見，但是，總少了一點人情味，而這項技藝正在漸漸的失傳中。謝森山，一位以畫電影海報為生的人，隨著時代的浮沉，一面保存這樣的特別技術，一面也努力的跟上科技的進步，認真的學習著。

二00九年四月二十九日備受矚目的第十一梯次電台執照開放政策，國際通訊傳播委員會（NCC）表示，將規畫釋出一百五十五張小功率執照，並且在現行地下電台「願意合法」的前提下，可以容納所有業者。對此，合法電台和地下電台各有顧忌之處。不過這項政策還在研擬當中，主因是正待廣電法和預算法修法完成，使執照拍賣制得以合法。
