Recently, the electronics industry is moved maturely on the mobile/tablet market. The next fast growing opportunity market will be the Internet of Things (IoT) and Wearable Deivces in the near future. This advanced technology/package need to provide the ideal solution for small form factor, thin profile, high electrical performance, multi-function integration and low cost are the most critical requirements...
Improvement of Laterally Diffused Metal Oxide Semiconductor (LDMOS) energy capability, Unclamped inductive switching (UIS) is used to characterize ruggedness in terms of the maximum avalanche energy that device can handle prior to destructive breakdown. Maximum amount of UIS energy (EAS) sustained by device before failure is evaluated and have linear relationship with number of device finger and device-width...
This paper demonstrates electrical degradation due to hot carrier injection (HCI) stress for devices with different bend gate structures by three-dimensional (3D) TCAD simulation. The amount and distribution of Si/SiO2 interface trap under different stress conditions were also evaluated by 3D simulation for the first time. Trap-related models were employed to perform accurate physics phenomena during...
A novel fast heuristic algorithm for operating reliability constrained unit commitment is proposed in this paper. The loss-of-load probability constraints are fulfilled by the iteration between the traditional spinning reserve constrained unit commitment and the operating reliability estimation. The features of the approach are the fastness of the algorithm and the robustness of the results. Even...
Financial derivative valuation is the key of the adoption of the International Financial Reporting Standards (IFRS), which are based on fair value accounting. When the derivatives do not have an active market, the inputs and methods for estimating their fair value will be more subjective and, the derivative valuation will be less reliable. The goal of this research is to design a derivative valuation...
In this article, the effect of AlN materials as passivation over AlGaN layer on AlGaN/GaN HEMTs performance was investigated firstly using electro-thermo-mechanical coupled methodology by both TCAD simulation and analytic calculation. It suggested that AlN passivation layer over AlGaN layer effectively spread the surface heat from the channel resulting in reduction of the lattice temperature and enhances...
In this paper, TCAD was used to simulate GGNMOS (Grounded-Gate NMOS) as an ESD protection device for 40V BCD. The physic models and the calibration method are discussed in order to get better accuracy on the result. The effects of device parameter on the ESD robustness are investigated by device simulation in order to achieve the desired ESD design window. The simulated holding voltage is in agreement...
The thesis analyzes and designs a remote update system based on GPRS technology. It mainly describes the application of GPRS technology in this system, the program structure in SCM (Single Chip Microcomputer), the subdivision of Flash code space and the design of communication protocol and system security. And it also briefly presents the specific achievement of the remote update system. The program...
Ball grid array (BGA) solder interconnecting is one of the key technologies in electronic packaging and assembly. Legislation of lead-free process has made the application of lead-free solder become wider in electronic products. Compared to the lead-tin solder, the relatively higher melting points of most lead-free solders call for a higher reflow temperature. Thus conventional integral-heating process...
The damage of structural safety of concrete is very large in harsh environment. Various properties of concrete can be improved by daubing protective agent on the surface of concrete. Influence of the protective agent on the impermeability and frost resistance and compressive strength of concrete is analyzed and determined by establishing experiment model and selecting protective agent. It is shown...
The v-belt linked pulley based continuously variable transmission (CVT) has been adopted extensively in internal combustion engine scooters (ICES) and zero emission scooters (ZES), in which CVT is used to increase the starting torque and also extend the speed operation range of the engines or motors. However, because of the inherent frictional mechanism, the efficiency of general CVT is relatively...
This paper proposes the hands-on implementations of the "Formosa middle size soccer robot", which is developed based on the intelligent vision fusion sensing architecture. The proposed autonomous soccer robot consists of the mechanical platform, motion control module, "MapCam360" omni-directional vision module, front vision module, image processing and recognition module, investigated...
