Profile: Kla-Pencor, Inc. specializes in providing process control & yield management solutions for the semiconductor and related microelectronics industries. Our products are used in a number of related industries, including wafer manufacturing, mask manufacturing, solar process development & control, medical device manufacturing, light emitting diode (LED) & data storage manufacturing, and general materials research. Wafer manufacturing tools include inspection, review, metrology and data management systems. Our specialized wafer inspection tools assess wafer surface quality & detect, count & 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.
