Description:
Secondary Ion Mass Spectrometry (SIMS) can determine elemental concentration as a function of depth, and can also image the local distribution of elements on surfaces and at different depths within materials and devices. The left image highlights the location of regions of oxygen contamination (green areas) at the interface in a patterned metallisation feature. (Copyright QinetiQ)
