The article covers examination of mathematical criteria that allow considering the process testing logical control systems at stage developing a program as completed. Two approaches for detecting errors in software, i.e. criterion intensity error detection and given value mean time to failure have been considered. An example calculation real task, turret block electrical automation system machi...
Semiconductor manufacturing is generally considered to be the most complex of manufacturing processes. Reasons for this include tightly constrained production processes, reentrant process flows, expensive sophisticated equipment, variable demand, high levels of automation and an ocean of data. Yet, despite the difficulties, semiconductor manufacturing is a key industry in many industrialized na...
Semiconductor fabrication is a manufacturing sequence with hundreds of sophisticated unit operations and it is always challenged by strategy development for ensuring the yield of defect-free products. In this paper, an advanced control strategy through integrating product and process control is established. The proposed multiscale scheme contains three layers for coordinated equipment control, ...
