Abstract
The new pattern placement metrology tool Leitz LMS 2020 is described a nd the performance demonstrated. The short term repeatability measured on a 13x13 grid is about 12 nm. The uncertainty of the tool is determ ined to be within 25 mn. The tool is also well-suited for critical dim ension (CD) monitoring purposes. The repeatability for CD measurements is better than 10 nm.
