Optical inspection machine Puma™

for patterned wafersfor the electronics industrydefect

Laser Scanning Patterned Wafer Defect Inspection Systems The Puma™ 9980 laser scanning inspection system incorporates multiple sensitivity and speed enhancements that enable capture of critical defects of interest (DOI) at throughputs required for high volume manufacturing for 1Xnm advanced logic and advanced DRAM and 3D NAND memory devices. Part of a portfolio of advanced wafer defect inspection and review tools, the Puma 9980 provides the highest throughput solution for production ramp monitoring by enhancing capture of defect types on advanced patterning layers. The Puma 9980 incorporates NanoPoint™ design-aware capability, which produces more actionable inspection results through increased defect sensitivity, improved systematic nuisance binning and tightened defect coordinate accuracy. Applications Line monitor, Tool monitor, Tool qualification
