Patent number: 9721751Abstract: A method for preparing plan-view transmission electron microscopy specimens is disclosed. The method employs isotropic vapor-phase etching in conjunction with one or more integrated etch-stop layers that give rise to a support membrane having a well-controlled, substantially uniform thickness. In some embodiments, the support membrane comprises an etch-stop layer that is formed using a high-precision formation process, such as atomic-layer deposition, oxidation, and the like. As a result, formation of the support membrane does not require additional processes, such as mechanical polishing or ion milling, to achieve its desired thickness. The method enables reduced specimen-preparation time, as well as simultaneous preparation of multiple specimens having large, uniformly thick areas for imaging.Type: GrantFiled: August 21, 2015Date of Patent: August 1, 2017Assignee: THE BOARD OF TRUSTEES OF THE LELAND STANFORD JUNIOR UNIVERSITYInventor: Timothy Stephen English
