Bump-less Cu/adhesive hybrid bonding is a promising technology for 2.5D/3D integration. The remaining issues of this technology include high Cu–Cu bonding temperature, long thermal-compression time (low throughput), and large thermal stress. In this paper, we investigate a Cu-first hybrid bonding process in hydrogen(H)-containing formic acid (HCOOH) vapor ambient, lowering the bonding temperature...
The use of CVD diamond films for electronic thermal management is quickly being realized as a viable application in high-power and high-temperature electronics, owing to the exceptional thermal properties of diamond and the recent advances in diamond CVD growth technology. In this study, a thick (~100 μm) CVD diamond film was grown on a 75-mm wafer consisting of AlGaN/GaN high electron mobility transistor...
Block matching motion estimation is a significant issue in image and video super resolution reconstruction. In order to decrease the number of search locations, the amount of computations, and enhance the prediction accuracy, an improved block matching motion estimation algorithm based on adaptive rood pattern search (ARPS) is proposed. Firstly, we use spatial correlation characteristic to predict...
Blockchains are on the top of the Gartner Hype Cycle 2016 and many start-ups are integrating blockchains into their technology portfolio. While blockchains have emerged in the context of financial applications, non-financial application areas are of interest as well. In this paper, modum.io is presented, a start-up that uses IoT (Internet of Things) sensor devices leveraging blockchain technology...
Formation tracking and transformation are the key problems in formation control of multi-AUV (autonomous underwater vehicle) system. In this paper, an improved self-organizing map (SOM) neural network method is proposed for solving the formation issues of a group of autonomous underwater vehicles (AUVs). All the AUVs in the formation are treated equal to be the leaders or the followers. The desired...
Advanced Driving Assistant System (ADAS) was widely learned nowadays. As crucial parts of ADAS, video-based application like lane markings detection and other objects detection, have become more popular than before. However, most methods implemented in such areas cannot perfectly balance the performance of accuracy versus efficiency, and the mainstream methods (e.g. Machine Learning) suffer several...
We have studied the structure and composition of the interface of diamond thin films deposited on Si substrates by chemical vapor deposition using atomic resolution electron microscopy, and electron energy loss spectroscopy. The latter technique allows the analysis of the relative Si to C composition as well as the nature of the bonding to determine the relative sp2/sp3 content of the diamond film...
The characteristics of aborigine's craft is an indispensable part of Taiwan's culture. It represents not only the uniqueness of Taiwan's traditional culture, but also illustrates the aesthetic meanings of each tribe with cultural traces. The traditional artistic and aesthetic connotations of the Taiwanese aborigines are distinctive. If we can understand the cultural characteristics of the aborigines...
We report on the development of sensor arrays comprising synthetic boron doped diamond (BDD) electrodes modified with metal catalyst nanoparticles. The latter are deposited onto the BDD electrodes surface by a physical vapor deposition process followed by de-wetting under oxygen-free atmosphere in high temperature conditions. The mean size of the particles is in the order of 10 nm, as characterized...
Diamond tool is widely used in the precision engineering field, and the higher requirements for the quality and efficiency of the diamond tool is put forward. Then the demand for the two-dimension precision positioning mechanism lapping arc edge diamond tool is becoming more and more urgent as well. In this paper, the project design of two-dimension precision positioning mechanism for lapping arc...
Diamond has attracted extensive attention for the next generation semiconductor devices, such as high-power, low-loss and high-frequency devices under high temperature conditions. In this paper, a radiation hardness of diamond unipolar devices such as Schottky barrier diode (SBD) and metal-semiconductor field-effect transistor (MESFET) was discussed. No any degradation of ideality factor or specific...
Loop tiling is a useful technique used to achieve cache optimization in scientific computations. However, general loop tiling techniques usually fail to improve parallelism in certain scientific computations due to dependences among execution steps. In this paper we implement and experiment on a tiling technique known as Parameterized Diamond Tiling designed based on the data dependences in the program...
With the ever increasing trend of cramming more transistors on the silicon and the consequential increase in the thermal design power, combined with stacked die and multiple die configurations inside the package footprint, optimized coolant chambers becomes an imperative design need to remove heat efficiently from the silicon. Liquid cooling is investigated to efficiently meet the challenges of high...
Xuanzang was extremely knowledgeable. He traveled to India, obtained large number of Sītra and treatises back to China, translated them into the Chinese language, and propagated extensively the principle of Consciousness-Only. On the other hand, Huineng was said to be illiterate, nonetheless, he broadly advocated the lineage of the Chan tradition which focused on the notion of “not establishing words...
Brand and product developments are the cores for small and medium-sized enterprises (SMEs) to keep their long-term competitiveness. The goals are to plan products which satisfy customer requirements and to ensure products are developed timely and to fit the market trend. This study began with research references related to resources, product benefits, and brand strategies for SMEs. The analyses include...
Affinity constants for a selection of Odorant Binding Proteins (OBPs) from mammalian and insect sources were determined toward volatile signature compounds from tobacco in the liquid phase using a fluorescent probe and competitive ligand binding. The most sensitive proteins were selected and these were immobilised on to diamond coated Surface Acoustic Wave (SAW) sensors to construct an array of eight...
Consumption of ultrapure water (UPW) during semiconductor manufacturing processes is an important topic. A new design of water-dispensing arm employs a small volume of UPW to remove slurry residues inside pad grooves. This innovative water conditioning arm, in contrast to the conventional atomizer and diamond disc, not only reduces UPW consumption by 87% but also reduces scratch defects. The small...
In order to fabricate Au micromirrors using a method of simultaneous molding and low-temperature Au-Au bonding, a fabrication method of molding and bonding tools using diamond blade dicing is investigated. Diamond blade dicing of synthetic quartz glass substrates produced smooth sidewall surfaces with root-mean-square roughness of 8 nm in the sample translation direction and that of 56 nm in the perpendicular...
Odorant binding proteins (OBPs) have been considered one of the best candidates for conceiving a biosensor to detect biochemical molecules and for odor sensor applications.
