Abstract:
Method for preparing site-specific, plan-view lamellae from multilayered microelectronic devices. A focused ion beam that is directed, with an etch-assisting gas, toward an uppermost layer of a device removes at least that uppermost layer and thereby exposes an underlying layer over, or comprising, a target area from which the site-specific, plan-view lamella is to be prepared, wherein the focused ion beam is in a face-on orientation in removing the uppermost layer to expose the underlying layer. In a preferred embodiment, the etch-assisting gas comprises methyl nitroacetate. In alternative embodiments, the etch-assisting gas is methyl acetate, ethyl acetate, ethyl nitroacetate, propyl acetate, propyl nitroacetate, nitro ethyl acetate, methyl methoxyacetate, or methoxy acetylchloride.

Claim (Index 18):
A method of  claim 11  in which repeating steps (c1) and (c2) until the exposed underlying layer is the one comprising the target area further comprises determining when the exposed underlying layer is the one comprising the target area by:\n acquiring an image an exposed underlying layer; \n determining a number of additional layers to be removed to expose the target area; and \n as additional layers are removed, counting the number of layers removed until the determined number of additional layers has been removed, leaving the target area exposed.
