概要（Overview）

The Archer 200 is an optical overlay control system designed to meet the performance and cost-of-ownership requirements for advanced design rules, including 32nm and double-patterning lithography. It features major improvements to its core optical design and an optional scatterometry measurement technology. This system offers tighter total measurement uncertainty, increased flexibility, higher productivity, and faster measurement. It uses industry-standard AIM or smaller µAIM targets.
