Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only the base substrate's anti-static design is used, then the device complexity is low, but the anti-static ability is limited
Solution Approach 1:
The anti-static protection system is divided into multiple independent components: an anti-electrostatic layer on the base substrate, an electrostatic conductive layer, and a first structure. This segmentation allows each component to perform its specific function while collectively providing comprehensive anti-static protection, resolving the contradiction between enhanced reliability and increased device complexity.
Solution Approach 2:
The electrostatic conductive layer extends from the surface of the base substrate to the side surface, creating a three-dimensional electrostatic discharge path. This dimensional extension ensures that static charges can be discharged from multiple locations and angles, significantly improving anti-static ability without requiring a complete redesign of the base substrate structure.
2Reliability
If an anti-electrostatic layer and electrostatic conductive layer are added, then the anti-static capability is enhanced, but the device complexity increases
Solution Approach 1:
The electrostatic conductive layer serves multiple functions: it connects the anti-electrostatic layer to the first structure, provides a discharge path on the side surface, and works协同 with the base substrate's anti-static design. This multi-functionality reduces the need for additional separate components, thereby enhancing electrostatic protection while limiting the increase in device complexity.
3Reliability
If the electrostatic conductive layer is placed on the side surface, then static charge discharge is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The electrostatic conductive layer is selectively positioned on the side surface of the base substrate where electrostatic discharge is most needed, rather than uniformly across the entire structure. This localized placement optimizes electrostatic discharge efficiency while reducing the overall manufacturing precision requirements compared to a complete coverage approach.
