Abstract

See full text

A lamella for observation on a transmission electron microscope and other analytical instruments includes multiple thin regions separated by thicker regions or ribs. In some embodiments, the lamella can be wider than 50 μm with more than 10 multiple thin regions, with each thin region may being as thin as 10 nm or even thinner. The process for making such lamellae lends itself to automation. The process is fault tolerant in that not all of the multiple thin regions need to be useable as long as one region provides a useful image. Redeposition is reduced because ion beam imaging is reduced in the automated process and because the ribs reduce redeposition between regions.
