The left image shows the sample as prepared in FIB (lift out method, mounted on an OmniprobeTM Cu grid). Clearly, the sample is too thick and is not flat. Ion milling in PIPS II was used to clean and thin the sample; sample was cooled to 80 °C. Stationary milling mode was selected and the gun was set at 300

This problem is overcome by milling a sample chamber with a focused ion beam. Figure 14 shows a FIB milled pit (114 × 108 × 65 μm) that was cut within 114 hours (FEI FIB200, Gasource, 30 kV, 11500 pA). The smooth floor produced by FIB milling provides excellent observation of the contained sample using a transmitted light microscope.

Broad ion beam milling utilizes ionized argon gas to bombard the sample, and physically sputter atoms from the sample. When done in cross section (also known as slope cutting), as demonstrated here, a carbide mask is positioned between the ion beam and the sample, which serves to define the position of the crosssection surface, as well as protect the front surface of the sample.

The ion slicer (JEOL EM09100IS) is a new device for a thin foil preparation with advanced argon ionmilling technique. The sample should be processed to 100 (± 10) μ m thick prior to the ion milling. A lowenergy and lowangle Arion beam with a size of 500 μ m irradiates the specimen (Fig. 1).

Thinning specimens to electron transparency for electron microscopy analysis can be done by conventional (2 4 kV) argon ion milling or focused ion beam (FIB) liftout techniques. Both these methods tend to leave ''mottling'' visible on thin specimen areas, and this is believed to be surface damage caused by ion implantation and ...
