Automation tools for semiconductor defect data analysis are becoming necessary as device density and wafer sizes continue to increase. These tools are needed to efficiently and robustly process the increasing amounts of data to quickly characterize manufacturing processes and accelerate yield learning. An image-based method is presented for analyzing process "signatures" from defect data distri...

At a highly automated facility in Oelde, Germany, high end appliance manufacturer, Miele produces around 300,000 electric ovens and cookers per year, all of which are comprehensively tested before delivery. To this end, the corresponding manufacturing cells are equipped with semiand fully-automatic testing stations. These stations benefit from integrated engineering and the close interaction of...

An analysis of the transportation systems used in flexible manufacturing systems is introduced in the paper. Based on the analysis an approach to the modelling and control of an automatic guided vehicles system (AGVS) is presented. It is aimed at a specifically delimited class of the AGV transportation systems. A special group of the colored Petri nets interpreted for control is used for the pr...

This paper presents new features implemented in the simulation environment VISTA which has been developed in our institute. The basic functionality dealing with the simulation of the manufacturing process and electrical characterization of semiconductor devices was extended by automatic experiment generation, parameter fit and optimization features. An example demonstrates the optimization of t...

This paper presents an original approach for automatic construction of a simulation model for complex manufacturing systems. The model generation is based on spatiotemporal product trajectories. The products therefore contribute directly to the control of the system. The formal generated model, a queuing network, is a permanent image of the real state of the system to be modelled; it can theref...

Non-Newtonian Fabrics are produced from Polymerization of Terephthalic Acid and Etylene Glycol. In view of manufacturing defects, the finished products are sold at a massive discount of 45%-65%. Presently manual inspection is being done, where an expert inspector detects only 70% of defects. Here, we are simulating automatic defect detection of fabrics by means of using computers. We proposed t...

Modern manufacturing systems are automated machines that perform the required tasks. The electric motors are perhaps the most widely used energy converters in the modern machine-tools and robots. These motors require automatic control of their main parameters (position, speed, acceleration, currents). With the help of an example, a DC motor system, the use of MATLAB/Simulink for comprehensive s...

Microfluidic-based heterogeneous immunoassays are reviewed in this article by first introducing the principle of immunoassay, followed by a discussion of microfluidic-based technology. Microfabrication, surface modification, solution dispensing and detection technology are discussed and their applications to biomolecular detection reviewed. In the future, improved manufacturing processes and in...
