Machines need to be individually qualified to run lots of certain families in semiconductor wafer fabrication facilities (wafer fabs). A qualification time window that lasts a couple of days is associated with each family and each tool. The time wind

The verification of a new or changed recipe is a common process control task in a semiconductor factory. It is also a prime example of the demanding integration challenges that Advanced Process Control (APC) is facing today. State-of-the-art process

In this paper we will present a multi-stage scheduling approach to generate robust schedules for a challenging aspect of semiconductor manufacturing called time-link areas. A time-link is a technologically induced time constraint between one or more

In this paper, we discuss requalification strategies for stepper tools in semiconductor wafer fabrication facilities (wafer fabs). Before processing lots on steppers, the steppers have to be qualified. A mathematical programming formulation is used p

Advanced process control (APC) is widely used in semiconductor manufacturing to adjust process parameters, ensuring a high product quality, while WIP flow optimization systems for scheduling & dispatching make decisions by assigning lots to tools for

Chaos theory has been a young research field with successful applications to a variety of areas. Even though former publications have assessed the question if production systems behave chaotic, little work has been published on real life production s

In this paper, we describe a hierarchically organised multi-agent-system prototype that is used for production control of semiconductor wafer fabrication facilities (wafer fabs). Starting from requirements for modern production control systems and ad
