Deflecting Conductive Layer Over Spacer Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Semiconductor modules experience performance degradation due to electromagnetic coupling between internal and external components, leading to signal cross-talk and altered operational parameters, particularly in radio-frequency functional areas.
Innovation Solution
A spacer structure made of non-conductive materials is used to deflect a conductive layer away from the semiconductor chip, increasing the distance between internal components and the conductive layer, thereby reducing coupling effects and allowing for signal routing over critical areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the conductive layer is placed close to the semiconductor chip for efficient signal routing, then signal routing efficiency is improved, but electromagnetic coupling between internal and external components increases causing performance degradation
Solution Approach 1:
A spacer structure made of non-conductive material (such as dielectric material or air gap) is introduced between the conductive layer and the semiconductor chip. This intermediary element increases the physical distance and reduces electromagnetic coupling while still allowing the conductive layer to route signals efficiently. The spacer acts as a mediator that decouples the harmful electromagnetic interaction while maintaining the functional signal routing path.
Solution Approach 2:
Instead of increasing horizontal separation distance, the invention utilizes the vertical dimension by placing the spacer structure between the conductive layer and the chip surface. This vertical separation in the Z-dimension effectively reduces electromagnetic coupling without compromising the lateral signal routing efficiency, thus solving the contradiction by transitioning the separation approach to another spatial dimension.
2Object-affected harmful factors
If the distance between the conductive layer and semiconductor chip is increased to reduce coupling, then electromagnetic coupling is reduced, but signal routing efficiency and component placement flexibility deteriorate
Solution Approach 1:
The spacer structure is not uniformly distributed but is strategically placed in specific locations where electromagnetic coupling is most problematic. This local application of spacers maintains signal routing flexibility in areas where coupling is less critical while providing enhanced isolation where needed, thus preserving ease of operation while reducing harmful electromagnetic effects.
