Defect Review SEM

Applied Materials®, Inc. has introduced the SEMVision DR-SEM system, a fully-automated defect review and classification scanning electron microscope specifically designed for in-line operation on advanced semiconductor production lines. The system uses several SEM imaging and material analysis techniques to improve chipmakers’ yield earning cycles during fab ramp-up and enable tighter yield control in volume production.

The system features Multiple-Perspective SEM Imaging (MPSI) technology that provides chipmakers with more information for accurately classifying and analyzing defect types than current SEM or optical imaging techniques. By enhancing both the topographic and material characteristics of defects, MPSI technology has enabled the development of an automatic defect classification (ADC) concept that classifies defects into types that are closely linked to the defects' source.




Beginning first half of 2020, GTI developed the capability of processing transparent wafers on DR-SEM and CD-SEM tools.

 H4 and H6, GaAs, Sapphire wafers, ZnO, Gallium Nitride wafers, Lithium Niobate wafers, SOI, and Quartz.

Critical Dimension Metrology Systems

Critical dimension (CD) metrology is one of the most essential technologies in semiconductor manufacturing. Much media attention is devoted to the ever shrinking feature sizes of microelectronic devices, as this parameter heavily influences speed of operation and power demands. Less appreciated is the fact that while the dimensions are on the nanometer scale, the manufacturing tolerances must be far smaller. This places great demands on the quality assurance assessment techniques.
