1Productivity
If conventional polarizing methods are used, then magnetic semiconductor devices can be polarized, but the scanning path length is long and power consumption is high
Solution Approach 1:
The patent divides the polarizing process into multiple scanning paths (first scanning path, second scanning path, third scanning path) with different directions and intervals. By segmenting the wafer into different regions and applying targeted scanning, the total scanning distance is reduced compared to conventional single-path methods, thereby lowering power consumption while maintaining polarizing throughput.
Solution Approach 2:
The patent employs dynamic adjustment of scanning parameters including variable scanning speeds, adjustable scanning intervals, and adaptable path selection based on wafer characteristics. The system dynamically optimizes the polarizing process by adjusting these parameters in real-time, reducing unnecessary scanning movements and power consumption while maintaining high productivity.

By segmenting the wafer into different regions and applying targeted scanning, the total scanning distance is reduced compared to conventional single-path methods, thereby lowering power consumption while maintaining polarizing throughput.
Solution Approach 2:
The patent introduces multi-dimensional scanning by implementing scanning paths in different directions (first direction, second direction perpendicular to first, third direction parallel to first). This dimensional approach allows the system to cover the entire wafer surface more efficiently by utilizing spatial relationships, reducing the total scanning path length compared to conventional single-direction scanning.
3Reliability
If electromagnetic elements are configured to generate strong magnetic field, then polarizing efficiency is improved, but power requirements increase
Solution Approach 1:
The patent configures electromagnetic elements to generate concentrated magnetic fields at specific locations where they are most needed (at the wafer surface during scanning). By localizing the strong magnetic field generation to only the necessary regions and times, the system achieves reliable polarizing效果 without requiring high power consumption across the entire system continuously.
Solution Approach 2:
The patent employs periodic activation of electromagnetic elements synchronized with the scanning process. The electromagnetic elements are activated in periodic cycles corresponding to the scanning paths, generating strong magnetic fields only when and where needed during the polarizing process. This periodic action maintains reliable polarizing效果 while significantly reducing overall power requirements compared to continuous high-power operation.
