概要（Overview）

KLA unveiled SpectraCD 100—the next-generation inline optical CD metrology system for advanced patterning process control at the 90-nm and 65-nm nodes. SpectraCD 100 utilizes a new hardware platform and advanced 3-D modeling capabilities to conduct complete profile measurements of yield-critical structures with a two-fold improvement in precision and tool-to-tool matching over our previous-generation SpectraCD system. These capabilities, coupled with SpectraCD 100’s production throughput and ability to non-destructively measure features down to 30-nm, provide chipmakers with an effective inline process control and product dispositioning tool for their most critical patterning steps.
