Abstract: An auxiliary stage for holding an electron microscope specimen includes a bottom part and a supporting part. The bottom part includes a first top surface, and the supporting part includes a second top surface and a side surface. The supporting part is fixed on the first top surface, and the side surface of the supporting part is substantially perpendicular to the first top surface of the bottom part. Therefore, the auxiliary stage is in a shape of a reversed T. A slit is embedded in the second top surface of the supporting part. A specimen holder is mounted in the slit, and a specimen is fixed on the specimen holder.

Abstract: A method of fabricating sample lamella for transmission electron microscopy (TEM) analysis is provided. A waiting-examination sample having an analysis target on the top surface of that is offered, and at least a mark around the analysis target is defined. A covering layer is covered on the top surface of waiting-examination sample. A holder is attached on the covering layer. A backside polishing process is performed to remove a portion of the waiting-examination sample until the mark is visible under the optical microscopy from the bottom surface of waiting-examination sample. An in-situ lift-out step is performed to pick up a thin membrane containing the analysis target and serve as the sample for TEM analysis.
