Patent number: 10282833Abstract: Optical verification testing of an IC includes obtaining images of the IC by, for each image: (i) illuminating the IC with excitation light, wherein the excitation light corresponds to a respective specific optical excitation of a predefined spectrum of optical excitations (e.g., wavelength spectrum); and (ii) detecting scattered light from the IC in response to the specific optical excitation. For each of a set of sub-regions of the images, the respective sub-region is mapped to at least one of (i) a specific sub-unit of a predefined set of sub-units (e.g., gates) of the IC and (ii) a null result, thereby creating a representation of a detected layout of the IC as an arrangement of the sub-units. The representation can be used to verify that an as-fabricated layout is consistent with an as-designed layout, to detect unauthorized modifications of the IC structure.Type: GrantFiled: November 30, 2016Date of Patent: May 7, 2019Assignee: Trustees of Boston UniversityInventors: Ronen Adato, Ajay Joshi, M.
