Incorporating a floating conductive layer within the insulator layer of micro-scale passive devices, which reduces the maximum electric field by floating at an intermediate voltage potential between the conductors, thereby mitigating the electric field's impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the insulator layer height is increased to reduce the maximum electric field, then the electric field reduction is limited with diminishing returns, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
A floating conductive layer is introduced as an intermediary element within the insulator layer. This conductive layer is positioned between the first and second planar conductors and is electrically isolated from both, creating intermediate electric field regions that reduce the maximum electric field strength without requiring excessive insulator height.
Solution Approach 2:
The electrical parameters of the insulator layer are modified by incorporating a conductive layer with specific electrical properties (conductivity, permittivity). This changes the electric field distribution characteristics, allowing for reduced maximum electric field strength while maintaining reasonable insulator layer dimensions.
2Object-affected harmful factors
If the insulator layer height is increased to reduce the maximum electric field, then some electric field reduction is achieved, but the manufacturing precision requirements increase significantly
Solution Approach 1:
The floating conductive layer serves as a mediator that actively manages electric field distribution. Its presence provides a more effective solution for electric field control compared to simply increasing insulator height, thereby reducing the stringency of manufacturing precision requirements for insulator layer thickness.
Solution Approach 2:
By changing the electrical parameters through the addition of the conductive layer, the system achieves better electric field control with less stringent dimensional tolerances, reducing manufacturing precision requirements.
3Object-affected harmful factors
If a floating conductive layer is added to reduce the maximum electric field, then electric field mitigation is significantly improved, but the device complexity increases
Solution Approach 1:
The floating conductive layer is introduced as a mediator within the insulator layer to reduce the maximum electric field between conductors. This approach provides effective electric field mitigation while maintaining a relatively simple overall device structure, as the conductive layer can be integrated into existing manufacturing processes.
