KLA
The KLA AIT UV Darkfield Inspection is a UV darkfield semiconductor wafer inspection system. The KLA AIT UV Darkfield Inspection originated in 2005. The KLA AIT UV Darkfield Inspection features software version 6.3.24.3 and SECS/GEM CIM.[1][2][3]
Darkfield wafer inspection systems are used to scan wafer surfaces and patterned layers for defects by collecting scattered light from features and particles while suppressing directly reflected background light. UV darkfield inspection tools belong to the metrology and inspection segment of semiconductor manufacturing equipment and are typically used for defect monitoring rather than for patterning or material removal.
Wafer inspection tools are placed at monitoring points throughout semiconductor process flows to check wafer condition after key fabrication steps. Darkfield optical inspection is commonly used after deposition, lithography, etch, clean, and planarization steps to identify excursion signals before additional value is added by downstream processing.
UV darkfield wafer inspection systems are used for defect inspection on semiconductor wafers. Typical application targets for this class include particles, haze, scratches, residue, and patterned defect signals on process layers where optical scattering can reveal localized nonuniformities.
