Abstract This paper introduces a high volume and fast turnaround TEM sample preparation method and requirements for a 300 mm inline DualBeam (FIB/SEM) system with “hands-off” full automation. It requires a factory automation system, robust automated recipes, and an ex-situ TEM lamella liftout system. It describes the recipe structure and TEM lamella lift out procedures. The focus is on fully automated TEM sample preparation for process monitoring in manufacturing line. Two successful examples are described to demonstrate the benefit of this method. The first one is TEM sample for CA profile at M1 level. The second is TEM sample for poly crystalline (PC) line profile at post-etch.

Software agents controlling production devices must maintain an up-to-date view of the physical world state in order to efficiently reason and plan their actions. Especially in a factory automation system, the world state undergoes rapid evolution. To enable accurate decision-making, the world view must constantly be synchronized with the changes. This paper discusses two approaches to updating the world view based on event notifications sent by web services representing production devices in a manufacturing system. One approach requires that a set of update rules is separately specified, whereas the other involves automatically deriving the update rules from the semantic web service descriptions. While this paper specifically focuses on the factory automation domain, both of the approaches presented are applicable to other domains as well. The main assumptions are that the domain is composed of world-altering web services, which provide adequate service interfaces to detect changes in their state, and that all relevant changes in the overall domain state can be directly derived from the service state changes.

This paper proposes an intervention support system between a manufacturing machine and a human for an anthropocentric factory automation system, which deals with feasible human interfaces and which treats unexpected problems in variable-kind variable-quantity production. In such production, repair tasks, dependent on non-deterministic human judgment, are required for raising the restorative capability of the system. An intervention support system using data carriers, engineering workstations, a point-of-production system, and PLC language is constructed. In this intervention support system, workers can understand the entire system, and heuristic information from tasks is easily accumulated as a result of experience at the shop-floor level.
