Abstract
A method of detecting failure causes in semiconductor processing systems may include receiving an indication of a failure in a semiconductor processing system and providing the indication of the failure as a query to a network representing the semiconductor processing system. The network may include nodes representing on-wafer effects and component functions, and relationships between the nodes that represent causal dependencies between the component functions and the on-wafer effects. The method may also include calculating a change in probabilities assigned to nodes representing the component functions resulting from the query, and generating an output indicating a probability of at least one of the component functions as a cause of the failure.
