Silicon Wafer Inspection With SWIR Cameras

Silicon inspection can be a challenging problem for silicon and semi-conductor manufacturers in terms of pattern alignment, pattern defect inspection and edge position bonding inspection. Defects do not initially affect the chip's functionality, but they do end up affecting the chip's reliability. This article discusses the use of silicon wafer inspection with SWIR cameras.

Production Ready 3-D Optical Profiler: ZeGage Pro

The ZeGage Pro and ZeGage Pro HR are scanning white light interferometers that provide 3-D optical surface profiling for the measurement of precision surfaces that require noncontact metrology. The base ZeGage Pro model delivers surface mapping at the nanometer scale, meeting the needs for most industrial surfaces. For smoother samples with a much finer surface finish, the ZeGage Pro HR offers more than 20X higher precision with 0.15 nm vertical precision.
