Unique photonic crystal technology enables “Ultrafast” film thickness measurement

Do you have a need for high-speed, high-sensitivity measurement of thickness irregularities in organic thin films for semiconductor?
Traditionally known for its high sensitivity, the optical film thickness measurement device “ellipsometer” has now achieved ultra-fast measurement through our unique photonic crystal
technology.

Differences from conventional ellipsometers

Conventional ellipsometers required the measurement target to be stationary.
Our ME/SE series ellipsometers can accurately measurements of samples on the move.
This provides overwhelming high speed.
