A fabrication method for integrating chip(s) onto a flexible substrate in forming a flexible micro-system. The method includes a low-temperature flip-chip and a wafer-level fabrication process. Using the low-temperature flip-chip technique, the chip is bonded metallically onto the flexible substrate. To separate the flexible substrate from the substrate, etching is used to remove the sacrificial layer underneath the flexible substrate. The instant disclosure applies standardized micro-fabrication process for integrating chip(s) onto the flexible substrate. Without using special materials or fabrication procedures, the instant disclosure offers a cost-effective fabrication method for flexible micro-systems.
Low-complexity time-domain linear equaliser for single-carrier block transmissions

Traditionally, frequency-domain equalisers have been used to equalise the single-carrier block transmission (SCBT) signals. However, to support the frequency-domain equaliser, two fast Fourier transform modules are required, which will increase the circuit complexity and chip area. A low-complexity time-domain linear equaliser for SCBT is proposed, which is less complicated than conventional frequency-domain equalisers, at the expense of an acceptable degradation in performance. For instance, for 60 GHz conference room non-line-of-sight channels, the complexity can be reduced by half at the expense of a 1.5 dB performance loss.

We present our study on the recognition of hydrogen isotopes by an open-cage fullerene through determination of binding affinity of isotopes H-2/HD/D-2 with the open-cage fullerene and comparison of their relative molecular sizes through kinetic-isotope-release experiments. We took advantage of isotope H-2/D-2 exchange that generated an equilibrium mixture of H-2/HD/D-2 in a stainless steel autoclave to conduct high-pressure hydrogen insertion into an open-cage fullerene. The equilibrium constants of three isotopes with the open-cage fullerene were determined at various pressures and temperatures. Our results show a higher equilibrium constant for HD into open-cage fullerene than the other two isotopomers, which is consistent with its dipolar nature. D-2 molecule generally binds stronger than H-2 because of its heavier mass; however, the affinity for H-2 becomes larger than D-2 at lower temperature, when size effect becomes dominant. We further investigated the kinetics of H-2/HD/D-2 release from open-cage fullerene, proving their relative escaping rates. D-2 was found to be the smallest and H-2 the largest molecule. This notion has not only supported the observed inversion of relative binding affinities between H-2 and D-2, but also demonstrated that comparison of size difference of single molecules through non-convalent kinetic-isotope effect was applicable.

Toward Wireless Backhaul Using Circuit Emulation Over Optical Packet-Switched Metro WDM Ring Network

Optical WDM metro-ring networks have been considered to be promising solutions for wireless backhaul. In this paper, we propose an integrated traffic control scheme (ITCS), which facilitates circuit emulation service (CES) for wireless backhaul over a previously proposed experimental optical packet-switched WDM metro-ring network, HOPSMAN. The ITCS seamlessly integrates variable-bit-rate (VBR) CES wireless with connection-less best-effort data, satisfying stringent QoS requirements and retaining maximal network throughput. The ITCS ensures efficient setup of CES connections by employing a simple mean-rate-based distributed admission control followed by a novel slot-marking reservation. The total connection setup delay is comprised of the setup queueing delay and slot-marking delay. While the slot-marking delay is nearly a ring time, the mean setup queueing delay is formally computed through an accurate approximation based on an M/G/m queueing analysis. We show simulation results to demonstrate that the ITCS accommodates remarkably high CES traffic loads while satisfying a wide range of delay requirements for wireless backhaul. Taking the background best-effort traffic into account, ITCS achieves exceedingly low delay, jitter, and delay bound for CES under various traffic loads and burstiness.

Ultrasonic vibration is widely applied in traditional metal forming to soften material and to increase formability. However, the effects of ultrasonic vibration on miniaturized workpieces must be studied before applying its benefits to metallic micro-forming. This study investigates the effects of applying ultrasonic vibration to micro-forming, along with two other factors: specimen size and grain size. Conventional (without ultrasonic vibration) and ultrasonic vibration micro-upsetting experiments were conducted using brass (C2600). Specimens of three different dimensions (phi 3 x 4.5 mm, phi 2 x 3 mm, and phi 1 x 1.5 mm) and of three grain sizes (12 mu m, 44 mu m, and 90 mu m) were used. The conventional micro-upsetting (CMU) experiment revealed the size-effect in which flow stress decreased with the miniaturizing of the specimen. Flow stress also decreased as the grain size increased, but at a smaller magnitude than that of the size-effect. Results show that ultrasonic vibration-assisted micro-upsetting (UMU) decreased the flow stress effectively, especially in miniaturized specimens. The amount of decrease was related more to the dimension than to the grain size of the specimen. (C) 2013 Elsevier B.V. All rights reserved.

The breakdown voltage (V-BD) and breakdown mechanism of junctionless (JL) poly-Si thin film transistor (TFT) were compared to the conventional inversion-mode (IM) TFT using fabricated devices and 3D quantum-corrected hydrodynamic transport device simulation. The simulated results are correspondent with experimental ones. The analyses of electric field distributions in on-state show that the channel of JL devices can equally share the voltage like a resistor, because there are no junctions formed between channel and source/drain. The JL TFT shows excellent breakdown characteristics; the off-state V-BD of 53.4V is several times larger than V-BD of 9.5V in IM TFT with same device size. JL devices have large potential for high voltage power metal-oxide-semiconductor devices and circuit applications. (C) 2013 AIP Publishing LLC.
1/f noise in micrometer-sized ultrathin indium tin oxide films

We have measured the low-frequency noises of ultrathin indium tin oxide films to investigate the effect of post annealing on the noise level. The noises obtained obey an approximate 1/f law in the frequency range f approximate to 0.1-20 Hz. The microstructures and grain sizes of our films were altered by adjusting the annealing conditions. An enhancement of the noise level was observed for those samples comprising smaller grains, where numerous grain boundaries exist. This enhancement in the noise level is ascribed to atomic diffusion along grain boundaries or dynamics of two-level systems near the grain boundaries. (C) 2013 AIP Publishing LLC.
