Latest Patents

Liu Chen holds a patent titled "Method for preparing TEM sample." This patent discloses a comprehensive method for preparing a TEM sample, which includes several steps. The process begins with providing a chip sample that has a metal protective layer on its first surface. The chip sample is then fixed onto a sample table of a focused ion beam (FIB) system. The first step involves performing FIB cutting on the metal protective layer to create a groove, with the inner surface of the groove being arc-shaped. This design allows for a gradual change in the thickness of the metal protective layer. Finally, a second FIB cutting is performed to thin the chip sample and form the TEM sample.
