What it is

The KLA Prometrix UV 1050 is a thin-film measurement system used in semiconductor manufacturing.[1][3][2]

How it works

The Prometrix UV 1050 uses broadband UV optics and dual-beam spectrophotometry to measure film thickness.[2]

A broadband xenon arc lamp serves as the light source for the system.[2]

The system includes a color camera for imaging, automatic focus on the measurement site, and stage resolution of 0.25 µm in x-y and 0.025 µm in z.[2]

The Prometrix UV 1050 supports simultaneous multilayer and enhanced single-layer (ESML) measurements over more than 500 discrete wavelengths.[2]

Applications

The Prometrix UV 1050 supports applications including polysilicon measurement, UV reflectivity, and simultaneous measurement of oxide and TiN thickness for CMP processes.[2]

The system accommodates wafer sizes of 100 mm, 150 mm, and 200 mm.[2]
