Finer pitch, thinner, and more valuable wafers make manufacturing reliability and traceability more important than ever. Cognex leads the way in precision alignment and wafer ID, despite process changes that dramatically affect a wafer’s appearance as it goes through production.
Cognex software pre-aligns wafers with high accuracy, reducing the fine alignment steps inside the process tool.
Wafer Fine Alignment
PatMax® feature location is accurate under the most challenging conditions.
In-Sight 1720 Series wafer readers, featuring a compact package and integrated illumination, reliably identify all SEMI codes.
PatInspectTM provides single step alignment and defect detection.
Bond Pad Inspection
Synthetic pattern training finds and inspects bond pads of almost any shape.
Probe Tip Inspection
Specialized software checks probe tips for wear, and ensures proper alignment.
