Wafer Quality Challenges
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.
