Title: Michael Moriarty: Innovator in Electron Microscopy Sample Preparation
Introduction
Michael Moriarty is a prominent inventor based in Portland, OR (US). He has made significant contributions to the field of electron microscopy, particularly in the preparation of sample lamellae. With a total of 9 patents to his name, Moriarty's work has advanced the methodologies used in transmission electron microscopy.
Latest Patents
One of Moriarty's latest patents is titled "Dose-based end-pointing for low-kV FIB milling in TEM sample preparation." This innovative method involves a system and computer-readable medium for forming transmission electron microscopy sample lamellae using a focused ion beam. The process includes directing a high-energy focused ion beam toward a bulk volume of material, milling away the unwanted volume to produce an unfinished sample lamella with exposed faces that may have a damage layer. After characterizing the removal rate of the focused ion beam, a low-energy focused ion beam is directed toward the unfinished sample lamella for a predetermined milling time. This allows for the delivery of a specified dose of ions per area, ultimately milling the sample lamella to remove a portion of the damage layer and produce a finished sample lamella that includes features of interest.
