Patent number: 10580615Abstract: Disclosed are a system and method, wherein, during manufacturing of integrated circuit chips on a semiconductor wafer, an in-line optical inspection is performed to acquire a two-dimensional (2D) image of an area of the semiconductor wafer and to confirm and classify a defect in the area. The 2D image is then converted into a virtual three-dimensional (3D) image. To ensure that the 3D image is accurate, techniques are employed to determine the topography of the surface shown in the 2D image based on material-specific image intensity information and, optionally, to filter out any edge effects that result in anomalies within the 3D image. The resulting 3D image is usable for performing an in-line failure analysis to determine a root cause of a defect. Such an in-line failure analysis can be performed significantly faster than any off-line failure analysis and, thus, allows for essentially real-time advanced process control (APC).Type: GrantFiled: March 6, 2018Date of Patent: March 3, 2020Assignee: GLOBALFOUNDRIES INC.Inventors: Kok Hin Teo, Jay A.
