The ever-shrinking world of semiconductors has always challenged the interplay of tool capability, process integration, and characterization. The fine line between structural or electrical success and failure has steadily been redefined from microns to nanometers with leading edge technology using terms with the likes of angstroms and layers of atoms. Failure modes at these nodes become increasing...
Early development of new semiconductor technologies heavily centers around the use of SRAM. For SOI technologies, voltage contrast (VC) inspection is commonly used to detect contact opens but the signal commonly associated with shorting, bright VC, has traditionally been ignored because too many failure analysis results have resulted in “no defect found”. For a recent SOI, Replacement Metal Gate (RMG),...

Drawing on theresource-based view (RBV), this study explores the capabilities portfolio of logistics service providers (LSPs) and sustainable competitive advantage. Cement transportation, as a kind of logistics services are selected, and the research model are built to analyze the portfolio of transport capabilities. Results show that different service strategies produce different impact on capability...
The concept of service supply chain helps us to consider service from different perspective. The service supply chain which is comprised by the service provider, service integrator and customer enterprise can create more value through collaborations. This paper studies the bulk cement transport business, analyzes the cooperation between the logistics service integrator and the logistics service provider...
Demand for high speed and more function microelectronic devices has driven semiconductor industry to continue developing technologies with ever-shrinking geometry. During technology development, Static Random Access Memory (SRAM) is often chosen as the process qualification and yield learning vehicle. Thus SRAM failure analysis is the major activity in any microelectronic device failure analysis lab...
The SRAM bitcell array has been traditionally used as a yield learning vehicle for new technologies. However, the yield of the SRAM bitcell is susceptible to parametric variations and subtle process defects/ variations. In this work a new functional array called the Tristated Inverter Array (TIA) is discussed which is much less susceptible to both parametric variation and subtle process defects while...
In this paper, a long-team immersion of concrete in dilute sulfuric acid is carried out. On the basis of the experimental data, a time serious prediction model of concrete corrosion in sulfuric based on support vector machine (SVM) is developed. The design steps and learning algorithm are also given. Comparing with the test result, this model has good predictive function, with the suitable reconstructed...
Product-like functional SRAM test chips have been widely used to capture systematic yield loss mechanisms during yield learning. Especially in early technology development, the top failing modes contributing to bit loss count are global patterns in the SRAM bitmap, which are highly suspected to be caused by defects in the peripheral control circuits. This paper describes a fault isolation flow on...
A maneuvering target tracking method for the high pulse-repetition frequency (HPRF) radars has to deal with two problems: range ambiguity and maneuvering uncertainty. Therefore, it can not be achieved by the traditional maneuvering target tracking methods directly. A new maneuvering target tracking method for HPRF radars is proposed to realize range ambiguity resolving and maneuvering target tracking...
This article aims to analyze the problems of housing mortgage loans. And it establishes an index system of credit risk evaluation according to the differences between developers and lenders. Based on artificial neural network, it establishes a credit risk evaluation and forecast model in housing mortgage loans, which will lay a foundation for the change of credit risk evaluation pattern and for the...
