Development of a rapid and automated TEM sample preparation method in semiconductor failure analysis and the study of the relevant TEM artifact
Automated TEM sample preparation using focused ion beam (FIB) followed by plucking has been proposed to be a fast and reliable method in semiconductor failure analysis with extremely short cycle time needs. Artifacts caused by sample supporting film to image quality, energy dispersive X-ray (EDX) and electron energy loss spectrum (EELS) analysis are discussed. Damage (amorphizing) to sample surface induced by Ga+ ion beam implantation during Pt protection film deposition was proved by TEM observation, and the method to avoid this damage are proposed.
