TL;DR: A novel oxide-silicon-oxide buffer structure to prevent damage to a plastic substrate in an ultralow temperature polycrystalline silicon thin-film transistor (ULTPS TFT) process is presented in this article.
Abstract: A novel oxide-silicon-oxide buffer structure to prevent damage to a plastic substrate in an ultralow temperature (<120/spl deg/C) polycrystalline silicon thin-film transistor (ULTPS TFT) process is presented. Specifically, an amorphous silicon film was inserted as an absorption layer into buffer oxide films. The maximum endurable laser energy was increased from 200 to 800 mJ/cm/sup 2/. The fabricated ULTPS nMOS TFT showed a performance with mobility of 30 cm/sup 2//Vs.

TL;DR: In this article, defect passivation was achieved on polycrystalline silicon thin-film transistors fabricated below 150°C by annealing and extracting H from SiNx:H interlayer dielectric.
Abstract: Plasma-free defect passivation is achieved on polycrystalline silicon thin-film transistors fabricated below 150°C by annealing and extracting H from SiNx:H interlayer dielectric. By annealing at 250°C without a plasma application, VT and μFE were improved from 11.5Vto3.5V and from 86cm2∕Vsto212cm2∕Vs, respectively. Improvement in performance is attributed to defect passivation by H diffusing out from SiNx:H. Dangling bonds and strained bonds can be acceptably passivated around 170°C, and 205°C, respectively. The activation energy for the diffusion of H into polycrystalline silicon was estimated to be 0.87eV.

TL;DR: This paper proposes a special server component including TOE (TCP/IP Offloading Engine) and H/W IPSec (IP Layer Security) for USN to solve the problems of large number of short term event packets of USN.
Abstract: The emerging Ubiquitous Sensor Network (USN) makes connection less datagrams and short event packets get popular A large number of short term event packets of USN can cause serious problems, such as interrupt handling overhead and context switching overhead Furthermore, heavy load of the packet security methods needs enough processing power Then, the more USN develops, the more network overheads would be loaded into host CPU To solve the problems, we propose a special server component including TOE (TCP/IP Offloading Engine) and H/W IPSec (IP Layer Security) for USN

Abstract: The emerging Ubiquitous Sensor Network (USN) makes connection less datagrams and short event packets get popular. A large number of short term event packets of USN can cause serious problems, such as interrupt handling overhead and context switching overhead. Furthermore, heavy load of the packet security methods needs enough processing power. Then, the more USN develops, the more network overheads would be loaded into host CPU. To solve the problems, we propose a special server component including TOE (TCP/IP Offloading Engine) and H/W IPSec (IP Layer Security) for USN.
