What it is

The QS 2200 is a Fourier-transform infrared (FTIR) spectrometer manufactured under the brand names Onto Innovation, Nanometrics, Accent, and Bio-Rad.[2][3][1]

How it works

General reference — not yet source-verified

An FTIR spectrometer uses a Michelson interferometer to modulate infrared radiation, generating an interferogram that is Fourier-transformed to produce an absorption spectrum.

The instrument measures the infrared absorption of a sample across a broad spectral range, enabling the identification of chemical bonds and molecular structures.

Where it fits in the process flow

General reference — not yet source-verified

In semiconductor manufacturing, FTIR spectrometers are employed as metrology tools for thin-film process control, typically positioned after deposition steps to verify film thickness, composition, and uniformity.

Applications

The QS 2200 is used for nondestructive wafer analysis and applied to the characterization and measurement of semiconductor materials as well as device manufacturing.[1]
