FF35 CT SEMI: Developed for applications in the semiconductor field

The Comet Yxlon FF35 CT SEMI X-ray system is an innovative, versatile high-resolution CT system for use in research and development and quality assurance. It was developed specifically for inspections in semiconductor-related industries. The FF35 CT SEMI meets the high SEMI® standards, including the hazard and safety standards SEMI® S2-0818 & SEMI® S8-0218, and is certified accordingly.

Measuring the finest inner structures with the FF35 CT Metrology

The Comet Yxlon FF35 CT Metrology takes the accuracy of CT-based dimensional control, e.g., measurements of finest inner structures, to the next level . It captures nearly unlimited measuring points in one CT scan decoupled from the measurement evaluation. Seamless defect analysis and nominal-actual comparison save time and reduce correction loops and correction costs for product samplings. The FF35 CT Metrology meets the standards of VDI/ VDE 2630.
