SEALING INSPECTION FOR MEMS
With the illumination source adjusted to your application requirements (1050nm - 1550nm), IRIS2100/IRIS2300 automatically detects smallest details such as bubbles and breaches that effect the functionality of the device. This advanced technology, in combination with our IR optimized software solution also detects delamination and eutectic bonding failures.
DEVICE DEFECT INSPECTION
IRIS2100/IRIS2300 enables you to detect and classify contamination and damages in the active device area. Our patented combination of visible and infrared illumination allows you to distinguish surface defects from defects deep inside the substrate.
