Summary:A method for attaching a prepared sample to a carrier in a focused ion beam chamber. The method includes reducing a temperature within the chamber to substantially below room temperature followed by moving the prepared sample adjacent to a substrate carrier surface. The temperature can be lowered sufficiently to establish a cryogenic condition in the chamber. Attachment of the prepared sample to the substrate carrier is done by controlling the focused ion beam to raster a target area of the surface in the absence of a gas deposition precursor, to sputter material onto the base of the sample and the substrate carrier surface, thereby binding the prepared sample to the substrate carrier.
