Abstract
A method for preparing an electron microscope specimen is provided. The method includes providing a wafer sample with an analysis region disposed thereon. A dicing process is performed to cut a sample piece from the wafer sample. The sample piece includes a target pillar structure wherein the analysis region is located on a top portion of the target pillar structure. A thinning process is performed to thin the top portion of the target pillar structure. The invention further provides an electron microscope specimen and a method of forming a 3D image.
