摘要: A method is provided for preparing a sample for cross-section analysis by a transmission electron microscope. Semiconductor samples containing recessed portions or unfilled structures are filled with a filling material so as to produce a planar top surface onto which a metal layer can be deposited for thinning the sample to a thickness of less than 100 nm by an FIB technique.
