Its three segments - Semiconductor and Component Test Systems (around 70% of sales), Mechatronics (handlers), and Services - deliver solutions for wafer sort, final test, and system-level testing. It also makes SEMs for photomask manufacturing and launched the Semiconductor Test Consortium in 2002. Recent partnerships, such as one with Emerson in 2025, focus on AI-driven test ecosystems.
