概要（Overview）

Archer AIM is an Advanced Optical Overlay Metrology product that improves stepper correction accuracy, provides precise data, and enables design rule segmentation. It delivers industry-leading precision performance, reduces total measurement uncertainty, and increases sampling rate. It also includes offline automatic recipe creation and real-time analysis software. The MPX option enables ‘on product’ monitoring of focus-exposure. Archer AIM targets new standards for lithography process control for 65-nm and beyond, reducing measurement uncertainty and enabling control of overlay error budgets. It integrates with KLA-Tencor’s software management products to provide comprehensive optical overlay metrology process control.
