NEXTIN, Inc. manufactures defect inspection and metrology systems for semiconductor and display industries in South Korea. The company offers AEGIS wafer inspection systems that detect various defects, such as bridges, thinning, protrusion, footing, scratches, and particles in film, pattern-generation, planarization, ion implantation, and cleaning processes across semiconductor manufacturing sequences. It also provides IRIS, a wafer metrology-inspection system to measure the vertical structures and find pattern defects during the HAR process steps in 3D semiconductor devices, as well as TSV processing in the advanced 3D packaging processes; and TWINS, an integration module to be installed onto the process equipment to measure the edge trimming processes and inspect its process defects. The company was founded in 2010 and is headquartered in Hwaseong-si, South Korea.
