PrimaScan™ System
The PrimaScan wafer defect inspection system delivers a flexible, high sensitivity solution at the lowest cost of ownership per pass.
Product Overview
The PrimaScan system utilizes laser scatterometry and imaging techniques leveraging proprietary optics and sensing technologies for reliable inspection of nanometer sized defects on a variety of opaque and transparent/semi-transparent substrates suitable for either R&D or high-volume manufacturing environments. With multiple detection channels, the system can detect, measure, characterize and image surface particles, scratches, pits, bumps, surface contamination, film or bulk wafer stress, voids/inclusions, including chips and cracks at the wafer edge.
The PrimaScan system addresses challenges in both incoming wafer quality control and in inline process monitoring. Capable of handling multiple substrate materials, it uniquely addresses inline process defect and contamination monitoring in wafer-based production environments.
Designed with versatility in mind the PrimaScan system can handle a variety of wafer sizes and substrate types
Applications
- Opaque or transparent wafer incoming quality (ICQ) inspection
- Process monitor wafer particle and contamination inspection
- Unpatterned blanket photoresist, dielectric or metallic coated wafer defect inspection
- Subsurface defectivity inspection for transparent and semi-transparent films and substrates
- Glass carrier wafer defect and contamination inspection for advanced packaging
- Glass wafer defect and contamination inspection for microfluidics, microlens arrays for AR/VR/MR, flat optics, etc.
