F37

An in-line thickness measurement system is a metrology tool used to check deposited or formed film layers without becoming part of the process chamber. Thickness metrology tools of this class are used to verify whether process films are within target after coating, deposition, growth, or related film-forming steps. In-line film metrology is commonly placed near production tools so process results can be checked quickly and fed back to the process flow.

The Filmetrics F37 performs measurements in-line and in real time. The Filmetrics F37 measures with accuracy better than ±1%. The Filmetrics F37 delivers measurements in seconds. The Filmetrics F37 operates totally outside of the deposition chamber. The Filmetrics F37 uses intuitive Windows software.^[1][2]

In-line thickness metrology sits after a film-forming step and before later operations that depend on film thickness being within target. Thickness checks are commonly used to confirm deposition, coating, or growth results before etch, patterning, bonding, or additional stack formation. In-line placement supports rapid process monitoring and adjustment in manufacturing flows.

Thickness metrology systems of this class are used where film thickness is a key process variable affecting device behavior, optical response, or later pattern transfer. Such tools are commonly applied to transparent or partly transparent process films in semiconductor, optics, and coated-substrate work. In-line use helps track uniformity and process drift across routine production runs.
