International Symposium on High Density Packaging and Microsystem Integration (HDP)

Organic thin film transistors (OTFTs) with modified gate insulator were demonstrated in this paper. The modified gate insulator layers consisted of SiO 2 as the gate insulator and OTS ( octadecyltrichlorosilane ) or PMMA (Poly(methyl methacylate)) as the modified layer. The devices with the modified layer had field-effect mobility larger than 10 -3 cm 2 /Vs, which was twice than that of the OTFT without modification. The on/off current ratio was increased one order of magnitude and reached more than 10 4 . The leakage current was decreased from 10 -9 A to 10 -10 A. The results demonstrate that using modified gate insulators can obviously improve the performance of the OTFTs.

Multi-view video plus depth (MVD) is a 3D video representation. In MVD, the depth map provides the scene distance information and is used to render the virtual view through Depth Image Based Rendering (DIBR) technique. The depth map coding error will induce distortion in the rendered virtual views. This paper proposes a mathematic model that can estimate the synthesized virtual view distortion induced by depth map compression, and the model is employed to the rate distortion optimization (RDO) in the depth map coding. Based on the rendered virtual view quality, a Lagrangian optimization adjustment scheme at Coding Unit (CU) level is proposed to improve the depth map encoding efficiency. Experimental results demonstrate that the proposed method can improve the BD-PSNR of virtual view for 0.62 dB, and the encoding complexity reduces compared with the view synthesis optimization (VSO) technique in the 3D-HEVC Test Model (HTM).

In this work, we have fabricated two bottom-gate zinc oxide thin film transistors (TFTs) with single-layer HfO 2 and double-layer HfO 2 -Al 2 O 3 dielectrics by atomic layer deposition (ALD). The TFT with HfO 2 -Al 2 O 3 dielectric exhibited better electrical characteristics, such as a higher field effect mobility of 6.1 cm 2 /V·s and a lower subthreshold swing of 0.124 V/decade. At the same time, the optical properties is also improved significantly with larger responsivity (6.05 A/W) and UV-to-visible rejection ratio (6.05×10 4 ). These results are attributed to lower interface trap states between channel layer and dielectric layer by an Al 2 O 3 interlayer.

The micro-pin-fins prepared on the back side of the power chip enable heat removal on the level of modern microsystem demands. Carbon nanotube (CNT) has been proven to be a potential material for micro-cooler because of its superior advantages including high thermal conductivity, good mechanical property and so forth. And there emerges various applications of CNT in the micro-cooler system. In the present paper, micro-pin-fin heat sink with gas impinging jet as the cooling medium is analyzed. The heat dissipation of forced air convection cooling with micro-pin-fin structures made of aligned carbon nanotube arrays has been taken into consideration. The three-dimensional computational fluid dynamics (CFD) simulation was carried out. The temperature distribution and the pressure drop are studied in the cases of various geometrical parameters of the micro-pin-fin heat sinks at the same heating power prescribed. The fluid flow and the heat transfer phenomena in the micro-pin-fins heat sinks are investigated. The heat removal efficiency of the air micro-cooler is evaluated. An array of 8×8 fins with the optimized fin-to-base length ratio achieves the best cooling effect.

An improved dual filed modular inversion algorithm which can support inversion operation in both GF(P) and GF(2∧m) is proposed in this paper. Compared with previous ones based on Extended Euclidean algorithm, it not only finishes modular inversion arithmetic in dual fields, but also operates much faster by more effective shift operations and avoiding time-consuming magnitude comparison. The simple addition/subtraction becomes the most complex operation in the new algorithm while the multiplication/division is replaced by cheap shifting, and thus only two adders and one subtraction device are required to complete its hardware implementation. The 256-bit modular inversion circuit based on the improved algorithm is implemented in SMIC 0.18 CMOS standard cell technology. The synthesis result indicates that the design is about 17% faster than that of previous algorithms while the area is only 5% larger. ©2009 IEEE.
