A novel silicon p-i-n diodes for detecting backscattering electrons in SEM was proposed and fabricated. The multi-annular configuration enables to provide better surface topography contrast of BSE image compared with traditional quadratic configuration. In this study, the multi-annular backscattered electron detector (BSED) can provide surface topography contrast of 82.11 nA/µm, which is 105% increase...
In this paper, we propose a new fabrication method to form a polysilicon thin-film transistor with a smiling SiO2 layer. The experimental results suggest that the short-channel effects can be significantly reduced because the trench oxide is utilized to block the drain electric field. Furthermore, the so-called S/D tie can help to overcome the self-hating for enhancing the thermal reliability. And...
A novel and interesting application of RFID was a banknote attached a tag to determine the authenticity of money and to stop counterfeits. At financial cryptography 2003, Juels and Pappu firstly proposed a practical RFID banknote protection scheme (RBPS) by using the optical and the electrical (RFID) contacts. RFID-enabled notes can be tracked by the legal law agency and verified by the merchant....
In this work, the excimer-laser-induced crystallization of amorphous silicon (a-Si) films was investigated numerically and experimentally. This study had investigated the effects of irradiating energy density on the grain size and structure by scanning electron microscopy (SEM). In the surface microstructure analysis of the laser-irradiated area, the critical fluences (full-melt threshold, FMT) between...
We extend the sharing scheme proposed by Mignotte in 1983 based upon Chinese remainder theorem (CRT) to devise a threshold secret sharing scheme for digital images. Given a secret image I and a set of n participants sharing I, our scheme encrypts I into n shadows in such a way that any group of r shadows can recover I while that of less than r shadows cannot where 2 les r les n. As compared to the...
Flexible electronics is a developing technology, and will have a lot of applications in the future; however, the technology lacks appropriate design flow and circuit design. In this paper, a representative digital circuit, an FIR filter, is designed on flexible a-Si thin film transistor (TFT) technology. To work under serious process variation of flexible a-Si TFT process, it is designed with bundled-data...
