Solution Overview
Problem
Current microstructures in photoelectric products suffer from low structural strength, short service life, and inefficient energy consumption due to heterogeneous layer combinations, leading to unstable performance and increased manufacturing costs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple structural layers are combined in a heterogeneous contact manner, then the microstructure can be formed with multiple functions, but the combination stability between layers decreases and overall structural strength reduces
Solution Approach 1:
The microstructure is divided into distinct functional layers (first structural layer, second structural layer, third structural layer) with clear interfaces. Each layer has specific functions and can be independently optimized, while the segmentation allows for controlled bonding interfaces that maintain overall structural strength despite heterogeneity.
Solution Approach 2:
The patent employs composite material structures where different materials are combined in specific layers. The first structural layer contains metal particles embedded in a matrix, creating a composite structure that provides both mechanical strength and functional properties. This composite approach allows multiple functions while maintaining inter-layer stability through material selection and interface design.
2Adaptability or versatility
If multiple structural layers are combined in a heterogeneous contact manner, then the microstructure can accommodate different materials and functions, but the service life becomes short due to low combination stability
Solution Approach 1:
The patent implements preliminary bonding between layers during the manufacturing process, creating strong inter-layer connections before the device is put into service. The first structural layer is bonded to the second structural layer, which is in turn bonded to the third structural layer, establishing a stable multi-layer structure that will maintain its integrity throughout the service life. This preliminary bonding action prevents delamination and structural failure during operation.
3Adaptability or versatility
If heterogeneous layer combination is used, then design flexibility is improved, but energy consumption increases and performance becomes unstable
Solution Approach 1:
The patent applies local quality by creating a hotspot structure in specific regions of the first structural layer, rather than uniformly distributing functional elements throughout the entire device. The metal particles are concentrated in particular areas to generate localized surface plasmon polaritons and hotspots, which reduces overall energy consumption while maintaining design flexibility for different functional configurations in different regions.
Applied Scientific Principles

AI summary
A microstructure with high bonding strength includes a substrate, a deposition layer, and a first dielectric layer. The substrate has a first surface. The first surface has a covered area and an exposed area. The deposition layer has a plurality of nanoscale metal particles. The deposition layer is disposed on the covered area of the first surface. The exposed area is exposed from the deposition layer. The deposition layer has a bonding face on one side away from the first surface. The first dielectric layer is disposed on the bonding face and contacts the exposed area. With the connection structure between the first dielectric layer and the exposed area of the substrate, a hotspot structure formed by the deposition layer and the first dielectric layer is more stably fixed to the substrate, thereby improving bonding strength of the overall structure.
