MueTec’s inspection solution for outgoing process control of the sawing process includes all areas of the framed wafer on foil. This includes the inspection of the sawing lines, as well as scratches, cracks, missing dies and particles. 

The inspection algorithm follows the recipe-free approach of the Argos product family. Many different product types can be inspected without creating specific recipes. 

KEY FEATURES

√ 380 mm framed wafer FOUP based handling

√ Optimized for multi-zone inspection of wafer, foil and frame. Detected defects include:

    Sawing line failures

    Cracks

    Scratches

    Bubbles in foil on frame and wafer

    Holes in foil

    Etc.

√ Data acquisition perfectly balanced to mechanical movements

√ Simultaneous brightfield and dark field inspection

NO RECIPE REQUIRED FOR EASE OF USE:

√  Enables productivity gains through minimum recipe customization

√  Ideal for fabs and packaging areas with many different devices & die sizes

√  No learning of alignment marks, chip size or wafer center necessary. Die layout data is not necessary

√  Recognition of active die area and EBR zone

√  Different sensitivities for different wafer areas

√  Avoiding false positives at zone transitions

√  Automatic adjustment of light intensity

√  Reflectivity of inspected layer is not necessary

√  Automatic defect recognition parameters by adaptive software algorithm
