High Spatial Resolution Time-of-Flight Secondary Ion Mass Spectrometry for the Masses: A Novel Orthogonal ToF FIB-SIMS Instrument with In Situ AFM

Figure 15

FIB-SIMS depth profile of ALD multilayer (five repeats of nominally 20 nm zinc oxide/20 nm aluminium oxide on a silicon substrate). 240 pA, 5 keV normally incident Ga+ bombardment. For clarity, each trace is on a differently scaled linear vertical axis. The surface of the sample is to the left of the figure, the substrate to the right.
