The method can include predicting an edge shape at a given future time with respect to the same inspection target pattern, setting a threshold corresponding to a required specification of the inspection target pattern, and predicting the time when the inspection target pattern fails to meet the required specification from the predicted edge shape and the threshold. The method can further include taking a plurality of images concerning the inspection target pattern at different times by use of an imaging apparatus, detecting edges of the obtained images, respectively, matching the detected edges of different imaging times, and obtaining a difference between corresponding edges to generate a difference vector after the matching. The edge shape of the future time can be predicted based on the generated difference vector and an interval between the imaging times."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pattern inspection method and semiconductor device manufacturing method","description":"In one embodiment, a pattern inspection method is disclosed.
