Measurement of the focal spot size on X-ray tubes with spot sizes down to 100 nm

Project: EU project

Project Details

Description

Enable component inspection to the nanometre scale.

The measurement performance of new X-ray systems that can inspect component dimensions down to the nanometre scale depends on the focal spot size and shape. However, no standard method exists for spot sizes below 5 µm.

Project develops new standard practices for characterising X-ray focal spots down to 100 nm with high levels of accuracy.

VTT MIKES identifies strategies for measurement of different gauge structures and performs SEM measurements on nanometre gauges.
