Abstract
A method and system for generating and managing a knowledgebase for use in identifying anomalies on a manufactured object, such as a semiconductor wafer, includes measures for adding, deleting, and organizing data from the knowledgebase.
Claims9
A method for generating a knowledgebase for use in labeling anomalies on a manufactured object, the method comprising the steps of:
- capturing an image of the object having an anomaly;
- preparing a pixel-based representation of the image;
- decomposing the pixel-based representation of the image into a primitives-based representation of the image to obtain an image geometry;
- isolating the anomaly on the primitives-based representation of the image without a reference image;
- comparing the primitive-based representation of the image with primitive sets for known anomalies in a knowledge base to locate the primitive set having a maximum similarity;
- presenting a label associated with the set of primitives having a maximum similarity to an operator;
- entering a label to be associated with the primitive-based representation of the image.
A method for generating a knowledgebase for use in labeling anomalies on a manufactured object, the method comprising the steps of:
- capturing an image of the object having an anomaly;
- preparing a pixel-based representation of the image;
- decomposing the pixel-based representation of the image into a primitives-based representation of the image to obtain an image geometry, the image geometry corresponding to the primitives-based representation;
- isolating the anomaly on the primitives-based representation of the image;
- storing the primitive-based representation of the image;
- and
- associating an assigned label with the stored primitive based representation of the image.
A method for augmenting a knowledgebase for use in labeling anomalies on a manufactured object, the method comprising the steps of
- capturing an image of the object having an anomaly;
- preparing a pixel-based representation of the image,
- decomposing the pixel-based representation of the image into a primitives-based representation of the image to obtain an image geometry;
- isolating the anomaly on the primitives-based representation of the image;
- comparing the primitives-based representation with primitive sets in a knowledgebase to find the primitive set with a maximum similarity;
- obtaining a first label associated with the primitive set having a maximum similarity;
- associating the first label with the primitives-based representation of the image provided that the similarity is greater than a predetermined similarity threshold;
- and
- adding the primitive-based representation and associated first label to the knowledgebase.
