Applying reticle enhancement technique recipes based on failure modes predicted by an artificial neural network

Abstract

Training data may be collected for each design intent in a set of design intents by identifying a set of failures that is expected to occur when the design intent is manufactured, and recording a failure mode and a location of each failure in the set of failures. Next, the training data may be used to train a machine learning model, e.g., an artificial neural network, to predict failure modes and locations of failures. The trained machine learning model, e.g., trained artificial neural network, can then be used to predict a set of failures for a given design intent. Next, for each predicted failure, a reticle enhancement technique (RET) recipe may be selected based on the failure mode of the failure, and the selected RET recipe may be applied to an area around the location of the failure.
