1Productivity
If automation of thin film sample preparation and observation is increased to meet the demands of miniaturized and complex semiconductor devices, then productivity and measurement precision improve, but device complexity and difficulty of detecting and measuring increase
Solution Approach 1:
The host control device evaluates the thin film sample based on the transmission electron microscope image, updates acquisition conditions based on the evaluation result, and outputs updated conditions to improve subsequent observations. This feedback loop enables continuous optimization of observation parameters without manual intervention, directly addressing the need for automation in complex semiconductor analysis
Solution Approach 2:
The system performs self-evaluation and self-adjustment of acquisition conditions through automated image analysis and condition updating. The host control device autonomously processes TEM images, evaluates sample quality, and modifies observation parameters without requiring external manual adjustment, enabling high-speed automatic TEM observation
2Measurement precision
If automation of thin film sample preparation and observation is increased to meet the demands of miniaturized and complex semiconductor devices, then measurement precision improves, but difficulty of detecting and measuring increases
Solution Approach 1:
The host control device evaluates the thin film sample based on the transmission electron microscope image and updates acquisition conditions based on the evaluation result. This automated feedback mechanism ensures optimal observation conditions are maintained, improving measurement precision while reducing the difficulty of detecting and measuring complex semiconductor structures
Solution Approach 2:
The system replaces manual mechanical adjustment of observation parameters with automated image-based evaluation and condition updating. The host control device uses software-based analysis to determine optimal acquisition conditions, substituting manual mechanical operations with automated computational methods that improve both precision and ease of measurement
