Collinear Interconnect Inductor Layout for Component Miniaturization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inductor members require space for arranging interconnects inside a magnetic layer, and with the miniaturization of electronic devices, there is a need to miniaturize these components.
Innovation Solution
The inductor member design includes a magnetic layer with interconnects extending in a first direction, where at least two interconnects are collinear and connected to terminal pairs, allowing for compact arrangement and miniaturization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple interconnects are arranged inside the magnetic layer, then the inductor functionality is improved, but the device size increases
Solution Approach 1:
Multiple interconnects are arranged collinearly along the same straight line within the magnetic layer, merging their spatial paths. This allows multiple inductor windings to share the same linear space rather than requiring separate winding areas, thereby improving inductor functionality while minimizing device size
Solution Approach 2:
The interconnects are arranged in a collinear configuration along the first direction (Y-direction) rather than traditional planar winding patterns. This one-dimensional linear arrangement optimizes space utilization within the magnetic layer, enabling compact device size while maintaining multiple interconnect functionality
2Ease of manufacture
If interconnects are arranged in traditional configurations, then ease of manufacture is maintained, but device miniaturization is limited
Solution Approach 1:
The magnetic layer is segmented into multiple regions along the first direction, with interconnects distributed at different positions along the collinear arrangement. This segmentation allows each interconnect to be manufactured independently using standard processes while achieving compact overall device size through the linear configuration
