Abstract:
1. A method comprising: exposing a first portion of a sample to a charged particle beam to generate a first image of the first portion of the sample; receiving, at a control system, a directional input; determining if a second portion of the sample adjacent to the first portion of the sample in a direction based on the directional input has been previously exposed to generate an image of the second portion; if the second portion has been previously exposed, retrieving the image of the second portion from a memory; and if the second portion has not been previously exposed, exposing a second portion of the sample adjacent to the first portion of the sample in a direction based on the directional input to a charged particle beam to generate a second image; combining at least a portion of the first image with the second image or the retrieved image of the second portion to generate a third image; and displaying the third image on a user interface.
