Solution Overview
Problem
Current cross section observing techniques do not facilitate easy comparison of sectional images obtained under different conditions, requiring significant time and labor for users to compare these images.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple sectional images are obtained under different observation conditions, then the comprehensiveness of cross section analysis is improved, but the time and labor required for comparison increases
Solution Approach 1:
The patent combines multiple sectional images obtained under different observation conditions into a single composite display. The image synthesis unit integrates sectional images from different conditions (e.g., different electron beam accelerations, different ion beam currents) into one unified view, allowing simultaneous comparison without requiring separate analysis of each image, thereby reducing time and labor while maintaining comprehensive analysis capability
Solution Approach 2:
The patent adds a new dimension to image presentation by displaying sectional images in a three-dimensional coordinate space. By mapping sectional images to spatial coordinates and rendering them with depth perception, the system enables intuitive comparison of images taken at different depths and conditions, transforming a two-dimensional comparison task into an immersive three-dimensional visualization that simplifies analysis
2Loss of information
If multiple sectional images are obtained under different observation conditions, then the detail information available for analysis is improved, but the complexity of the observation system increases
Solution Approach 1:
The patent implements a universal observation system that can handle multiple observation conditions through a single integrated apparatus. The system accepts sectional images from various conditions (different electron beam parameters, ion beam parameters, observation angles) and processes them uniformly through the same storage and synthesis units, eliminating the need for separate specialized systems for each observation condition while preserving all detail information
Solution Approach 2:
The patent introduces an image synthesis unit as an intermediary component that mediates between multiple image sources and the final display. This intermediary processes and integrates images from different observation conditions, managing the complexity by providing a standardized interface that handles diverse input formats and parameters, thereby reducing the overall system complexity while maintaining comprehensive detail information

AI summary
This cross-section observation device bombards an object with a charged particle beam to repeatedly expose cross-sections of the object, bombards at least some of the cross-sections from among the plurality of the exposed cross-sections with a charged particle beam to acquire cross-sectional image information describing each of the at least some of the cross-sections, generates for each of these cross-sections a cross-sectional image described by the cross-sectional image information acquired, and generates a three-dimensional image in which the generated cross-sectional images are stacked together. This cross-section observation device displays a first three-dimensional image along with a second three-dimensional image, the first three-dimensional image being a three-dimensional image from the stacking of first cross-sectional images, which are cross-sectional images of the cross-sections described by the corresponding cross-sectional image information acquired on the basis of a first condition, and the second three-dimensional image being a three-dimensional image from the stacking of second cross-sectional images, which are cross-sectional images of the cross-sections described by the corresponding cross-sectional image information acquired on the basis of a second condition.
