About NextIn

NextIn, Inc. is a global leader in semiconductor metrology and defect inspection, specializing in high-sensitivity optical systems for advanced chip manufacturing. Headquartered in Hwaseong, South Korea, and supported by a specialized R&D center in Israel, the company provides critical technology that enables semiconductor fabs to maximize yield and stabilize complex nanômetro-scale processes. Led by CEO Taehoon Park, NextIn has evolved from a venture-backed startup into a KOSDAQ-listed powerhouse. The company’s flagship AEGIS series utilizes proprietary dual-illumination (bright-field and dark-field) technology to detect micro-pattern defects that are invisible to standard systems. Furthermore, its IRIS platform is specifically engineered for the challenges of 3D semiconductor architectures and HBM (High Bandwidth Memory), providing the deep-structure metrology essential for AI-era hardware. As a strategic asset for NIF Security of Critical Technologies, NextIn ensures South Korea’s industrial resilience by providing indigenous, world-class inspection solutions that reduce dependency on foreign equipment providers.
