Abstract The failure analysis community working on highly integrated mixed signal circuitry is entering an era where simultaneously System-On-Chip technologies, denser metallization schemes, on-chip dissipation techniques and intelligent packages are being introduced. These innovations bring a great deal of defect accessibility challenges to the failure analyst. To contend in this era while aiming for higher efficiency and effectiveness, the failure analysis environment must undergo a disruptive evolution. The success or failure of an analysis will be determined by the careful selection of tools, data and techniques in the applied analysis flow. A comprehensive approach is required where hardware, software, data analysis, traditional FA techniques and expertise are complementary combined [1]. This document demonstrates this through the incorporation of advanced scan diagnosis methods in the overall analysis flow for digital functionality failures and supporting the enhanced failure analysis methodology. For the testing and diagnosis of the presented cases, compact but powerful scan test FA Lab hardware with its diagnosis software was used [2]. It can therefore easily be combined with the traditional FA techniques to provide stimulus for dynamic fault localizations [3]. The system combines scan chain information, failure data and layout information into one viewing environment which provides real analysis power for the failure analyst. Comprehensive data analysis is performed to identify failing cells/nets, provide a better overview of the failure and the interactions to isolate the fault further to a smaller area, or to analyze subtle behavior patterns to find and rationalize possible faults that are otherwise not detected. Three sample cases will be discussed in this document to demonstrate specific strengths and advantages of this enhanced FA methodology.

Hybrid Circuit

The medium voltage DC (MVDC) type system can connect multiple terminals to a common MVDC bus, so it is possible to connect several renewable DC power sources to the common MVDC bus, but a DC circuit breaker is needed to isolate short circuit accidents that may occur in the MVDC bus. For this purpose, the concept of a hybrid DC circuit breaker that takes advantage of a low conduction loss contact type switch and an arcless-breaking semiconductor switch has been proposed. During break the hybrid switch, a dedicated current commutation device is required to temporarily bypass the load current flowing through the main switch into a semiconductor switch branch. Existing current commutation methods include a proactive method and a reverse current injection method by a LC (Inductor-capacitor) resonant circuit. This paper proposes a power circuit of a new MVDC hybrid circuit breaker using a low withstanding voltage capacitor branch for commutation and a sequence controller according to it, and verifies its operation through an experiment.

This study aims at analyzing: 1) the effect of mental accounting on placement of funds for working capital in small- and middle-scale business, 2) the effect of placement of funds for working capital on company performance in small-and middle-scale business, and 3) the effect of mental accounting on company performance through placement of funds for working capital in small- and middle-scale business.The population of this study was all the small- and middle-scale businesses in Lombok Island. Samples were collected by using judgment sampling of non probability sampling. The samples taken were the small- and middle-scale businesses of pottery industry which have exported their goods. The respondents were the managers and owners of small- and middle-scale businesses. The method of data analysis employed in this study was Generalized Structured Component Analysis. The finding of this study showed that mental accounting is rational by nature and have significant effects on company performance through placement of funds for working capital in small-and middle-scale business.This phenomenon is grounded from the fact that most managers and owners of those small- and middle-scale businesses are men who are on their productive age, and have more than 10 years of experience. The placement of funds for working capital is shown by the efficiency of cash, receivable and inventory management which in turn improve the company performance.
