Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic fields with different orientations are applied during testing, then test reliability is improved, but device complexity increases
Solution Approach 1:
The testing system dynamically adjusts the magnetic field orientation by rotating the component through different angular positions (e.g., 0°, 45°, 90°, 135°) relative to the magnetic field direction. This dynamic repositioning allows the same physical testing apparatus to evaluate multiple orientation-dependent parameters without requiring separate fixed installations for each angle, thereby improving test reliability while controlling device complexity.
Solution Approach 2:
The testing method changes the magnetic field orientation parameter systematically across multiple test runs. By varying the angle between the magnetic field vector and the component's structural features (such as vias or gate material orientations), the system detects orientation-dependent manufacturing defects. This parameter variation approach enables comprehensive reliability assessment using a single versatile testing device.
2Measurement precision
If multiple magnetic field orientations are used for testing, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The testing process employs periodic action by systematically rotating the component through a defined sequence of angular positions (e.g., 0°, 45°, 90°, 135°) and performing measurements at each position. This periodic rotation pattern allows efficient coverage of orientation-dependent parameters while maintaining a structured, repeatable testing rhythm that minimizes idle time and optimizes the measurement process.
Solution Approach 2:
The system performs preliminary actions by pre-positioning the component at optimal angular orientations before each measurement phase. The rotation mechanism is prepared in advance to align the component's critical features with the magnetic field direction, ensuring that measurements are taken at the most informative angles without requiring time-consuming adjustments during the actual measurement process.

This approach enhances the accuracy and reliability of component testing by identifying reliability issues related to inhomogeneous manufacturing processes, such as poorly filled vias or inhomogeneous gate material, thereby improving the quality of component deliveries.
Implementation Method 1
The discovery is based on the finding that the Lorenz force along with quantum mechanical changes affect charge carriers so that they are pushed into different areas of the conductive material, changing characteristics of the device under test or the component under test due to magnetic fields of different magnetic field orientations.
