Abstract
Description
technical field
[0001] The invention relates to the field of semiconductor chip analysis, in particular to a sample fixing device on a scanning electron microscope sample stage during the preparation and analysis of test samples. Background technique
[0002] With the development of semiconductor integrated circuits, electron microscopes are more and more widely used in the microstructure analysis of products. IC (Integrated Circuit) manufacturing is basically built up by layers of patterns, and in order to understand the structure of the stacked patterns to improve the process or solve the failure problem in the process, it is often observed through an electron microscope by using a destructive cutting method , while cutting the cross section (CROSS SECTION) and observing the (crystal garden) cross section are the most basic means to detect the quality of the process. Electron microscopes generally include scanning electron microscope SEM (Scanning Electron Microscopy), tr...
