KLA-Tencor’s wafer manufacturing tools include inspection, review, metrology and data management systems. Specialized wafer inspection tools assess wafer surface quality and detect, count and bin defects during the wafer manufacturing process and as a critical part of outgoing wafer inspection. Wafer geometry systems ensure the wafer is extremely flat and uniform in thickness, with precisely controlled wafer surface topography. Specifications for wafer defectivity, geometry and surface quality are tightening as the dimensions of transistors become so small that the properties of the substrate can substantially affect transistor performance.
