Substrate Manufacturing
KLA’s substrate manufacturing portfolio includes defect inspection and review, metrology and data management systems that help substrate manufacturers manage quality throughout the wafer fabrication process. Specialized wafer inspection and review tools assess wafer surface quality and detect, count and bin defects during production and as a critical part of outgoing wafer qualification. Wafer geometry systems ensure the wafer shape is extremely flat and uniform in thickness, with precisely controlled wafer shape topography. Data analysis and management systems proactively identify substrate fabrication process excursions that can lead to yield loss. KLA’s substrate manufacturing systems support process development, production monitoring and final quality check of a broad range of substrate types and sizes including silicon, prime silicon, SOI, sapphire, glass, GaAs, SiC, GaN, InP, GaSb, Ge, LiTaO3, LiNBO3, and epitaxial wafers.
