The present invention provides, in one aspect, a method of imaging a microelectronics device 100 . The method comprises cleaning, when contaminants are preset, a sample of a microelectronics device 100 to be imaged with a first solution comprising hydrofluoric acid, an inorganic acid and water, exposing the sample to a second solution comprising hydrofluoric acid, an inorganic acid and an organic acid, wherein the second solution forms a contrast between different regions within the sample, and producing an image of the contrasted sample.
