A first image of a first portion of a wafer is received from a first image capturing device. A second image of a second portion of the wafer is received from a second image capturing device, wherein an image capturing device transform defines a first relationship between the first image capturing device and the second image capturing device. A first fiducial pattern in the first image and a second fiducial pattern in the second image are identified, based on the image capturing device transform, a fiducial transform that defines, based on a specification for the wafer, a second relationship between the first fiducial pattern and the second fiducial pattern, and a threshold value configured to identify low contrast fiducial patterns on wafers. An alignment of the wafer is determined based on the identified first and second fiducial patterns."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for aligning a wafer for fabrication","description":"Described are computer-based methods and apparatuses, including computer program products, for aligning a wafer for fabrication.
