How does a wafer inspection system work?
With its multi-image capture technology, the system can reliably detect even low-contrast defects, enabling 100% monitoring of wafer production. It classifies the wafers into different quality classes based on the data collected. Line-scan camera technology allows on-the-fly inspection with a moving sample, enabling the highest throughput.
How to check incoming wafers?
Also the bulk resistivity of the wafers can very quickly be checked by non-contact eddy current techniques as well as the thickness and total thickness variation of the wafer by capacitance techniques. The advent of photoluminescence imaging has been the biggest revolution in incoming wafer inspection.
Why do I need to remove a wafer before processing?
Wafers that do not meet the desired quality can thus be removed before further processing – ensuring high quality for excellent module effectiveness and permanently reduced warranty costs.
