CHB Wafer Slip Detector
Wafer Detect Kit is a proven solution to reduce and eliminate costly wafer misalignments and breakages which can result in contaminated lots and system downtime.
Wafers can be misaligned or broken due to robot issues or process chamber “sticking” or “sliding”
Early detection of wafer misalignment is crucial for diagnosing robot issues
Easy to install and compatible with 4”, 6”, 8” wafers
Wafer Detect Kit will stop wafer processing if it detects a wafer that is misaligned
Detection capability for Ch. A or Ch. B position depending on customer production demands
Wafer Detect Kit has been qualified and is currently operating at customer sites globally (200 kits)
Wafer Detect Kit
Wafer Detect Kit is easy to install, reliable, and adjustable for various wafer shapes and sizes to reduce wafer misalignments and handling issues.
Prevent Possible Wafer Breakage
Detect wafer misalignment in Chamber A/B. Al “Sticking” can cause greater chance for wafer misalignment and subsequent wafer breakage.
Field Proven
Installed over 200 customers and has been proven to reducing wafer breakages
Greater Accuracy with 3 Sensors
Three detection sensors emit a beam onto 3 positions on the outside pedestal, forming a triangular beam area immediately on the wafer.
Adjustable Sensitivity
Fine adjustment to sensors can me made depending on wafer type, reflectivity, and wafer shapes
3 Way Sensors
