Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The design of traditional thin film passive components requires large space areas, leading to inefficient layout designs in high-frequency electronic products, as the size and features of these components cannot meet the needs of miniaturization and high-frequency characteristics.
Innovation Solution
The integration of a thin film resistor structure composed of multiple rectangular segments, electrically connected through metal plugs or wiring at different layers, reduces the overall layout area while maintaining predetermined resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional thin film passive components are used, then the components can be manufactured with good workability, but large space areas are required leading to inefficient layout design
Solution Approach 1:
The thin film resistor structure is divided into multiple rectangular segments arranged in parallel, which are then electrically connected through metal plugs or wiring at different layers. This segmentation allows the resistor to achieve the required resistance value while occupying significantly less layout area compared to traditional single-structure thin film resistors.
2Area of stationary object
If the layout area of active components is shrunk to accommodate thin film passive components, then space utilization improves, but the design efficiency decreases
Solution Approach 1:
The patent utilizes three-dimensional space by arranging multiple rectangular resistor segments in parallel and connecting them through metal plugs or wiring at different layers. This multi-layer approach allows the resistor structure to achieve compact footprint while maintaining design efficiency, as the vertical stacking reduces the horizontal layout area required.
