Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional substrate is used without micro conductors, then the manufacturing process is simple, but the semiconductor element suffers from characteristic deterioration due to electric fields from static electricity
Solution Approach 1:
The substrate's electrical properties are changed by incorporating micro conductors into the organic insulating material, transforming it from a simple insulator to an electrically active component that can shield against harmful electric fields while maintaining mechanical substrate functions
Solution Approach 2:
The substrate is constructed as a composite material combining organic insulating material with dispersed micro conductors, creating a new material system that simultaneously provides insulation and electromagnetic shielding properties
2Reliability
If micro conductors are added to the substrate to shield electric fields, then the semiconductor element is protected from characteristic deterioration, but the substrate manufacturing becomes more complex
Solution Approach 1:
The substrate manufacturing process merges the formation of the organic insulating material layer with the incorporation of micro conductors into a single integrated process, eliminating the need for separate shielding layer fabrication and reducing overall manufacturing complexity
Solution Approach 2:
The micro conductors are incorporated during the substrate formation process itself, allowing the substrate to self-generate its electric field shielding capability without requiring additional protective layers or post-processing steps
