Latest Patents

Yanrong Qiu holds a patent titled "Method for preparing a TEM sample." This patent outlines a comprehensive process that includes several steps. The first step involves providing a thin-film pre-sample with undesirable voids. The second step consists of performing a first cutting with a focused ion beam (FIB) to form the TEM sample located in the target region of the thin-film pre-sample. The third step includes depositing a first material layer using an atomic layer deposition (ALD) process to fill the voids in the TEM sample. Finally, the fourth step involves performing a second cutting with a second FIB to achieve the target thickness of the TEM sample. This method effectively reduces or eliminates ion beam cutting marks related to the voids in the thin-film pre-sample.
