Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional fabrication methods are used to improve computing power and spatial density, then device performance is enhanced, but total energy consumption increases
Solution Approach 1:
The patent applies composite materials by combining ferromagnetic layers with dielectric layers to create a ferromagnetic-dielectric composite material. This composite structure enables improved magnetic properties that reduce energy consumption in semiconductor devices while maintaining computing power, directly addressing the contradiction between enhanced performance and increased energy usage
2Manufacturing precision
If ferromagnetic layers are patterned and transferred using conventional methods, then material integration is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent segments the fabrication process into distinct substrate assemblies: a patterning substrate assembly for creating precise ferromagnetic layer patterns, and a receiving substrate assembly for final integration. This segmentation allows complex pattern transfer operations to be performed in a controlled manner while simplifying the overall manufacturing process through modular assembly
Solution Approach 2:
The patent introduces carrier release layers as intermediary elements between the ferromagnetic layers and the substrates. These carrier release layers facilitate the transfer of patterned ferromagnetic layers from the patterning substrate to the receiving substrate, reducing direct complexity in the manufacturing process while maintaining high precision
