Claim:
1. A method for forming one or more electron microscopy specimens on a substrate, the method comprising: providing the substrate comprising a first material, the first material having a first etch rate in a first etchant; forming a first layer on a first surface of the substrate, wherein the first layer is formed via an atomic-layer-deposition process, and wherein the first layer comprises a second material having a second etch rate in the first etchant, and further wherein the second etch rate is slower than the first etch rate; disposing a first specimen on the substrate in a first region such that the first layer is between the substrate and the specimen; and forming a first support membrane in the first region by exposing the first material in the first region to the first etchant, the first support membrane comprising a first portion of the first layer.
