Abstract:
A method of preparing a test sample for electron microscopy analysis, comprising:providing a sample polisher comprising a holder; providing a chip segment to be tested having a first polishing end, a second polishing end, and a pre-selected testing point between the first polishing end and second polishing end; attaching the chip segment to be tested to the holder; polishing the first polishing end of the chip segment by using the sample polisher to generate a first polished cross section, wherein the chip segment to be tested has a first predetermined distance between the first cross section and the testing point; detaching the chip segment to be tested from the holder; attaching a carrier segment to the first cross section of the chip segment to be tested; attaching the conjoined carrier segment and the chip segment to be tested to a pad segment so as to form a stacked structure; attaching the stacked structure to the holder; and polishing the second polishing end of the chip segment to be tested to generate a second polished cross section, wherein the chip segment to be tested has a second predetermined distance between the second polished cross section and the testing point.
