During wafer fabrication, process data, equipment data, and lot history will be automatically or semi-automatically recorded and accumulated in database for monitoring the process, diagnosing faults, and managing manufacturing. However, in high-tech industry such as semiconductor manufacturing, many factors that are interrelated affect the yield of fabricated wafers. Engineers who rely on perso...

Data fabrication, incorrect collection strategies and poor data management, are considered detrimental to high-quality scientific research. While poor data management have been occasionally excused, fabrication constitutes a cardinal sin - scientific misconduct. Scholarly examinations of fabrication usually seek to expose and capture its prevalence and, less frequently, its consequences and cau...

In the era of big data, it is often the case that the selfsimilar rare categories in a large data set are of great importance, such as the malicious insiders in big organizations, and the IC devices with defects in semiconductor manufacturing. Furthermore, such rare categories often exhibit multiple types of heterogeneity, such as the task heterogeneity, which originates from data collected in ...

recently, as the result of the development in modern imaging, computerized three dimensional data processing and advanced engineering techniques, an prosthesis that match the skeletal anatomy can be accurately designed from computer aided design (cad) technique and the physical model of prosthesis or skull replica can be produced through rapid prototyping (rp), rapid tooling (rt), and computer ...

Although the membrane process is recognized as a green technology and is considered as a key player in the process intensification movement, it is not widely known that the fabrication of membrane itself generates significant amount of waste. With the growing membrane market, more efforts must be placed on improving the sustainability of membrane fabrication such as replacing toxic organic solv...

an autonomous underwater vehicle (auv) with less noise and vortices as well as efficient power consumption, is pursued in this research by inspiration of shark swimming. design, hydrodynamic analysis, modeling, fabrication, navigation, and control of this novel auv is the main goal of this research. detailed explanation of the test and experiment with a brief overview on fabrication are provide...

Rapid prototyping (RP) techniques are a group of advanced manufacturing processes that can produce custom made objects directly from computer data such as Computer Aided Design (CAD), Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) data. Using RP fabrication techniques, constructs with controllable and complex internal architecture with appropriate mechanical properties can be ach...
