Solution Overview
Problem
Existing electronic components, particularly those made from silicon, are limited in size reduction and efficiency due to the atomic size of silicon, and they often suffer from material stresses and uneven coatings that affect performance.
Innovation Solution
Utilizing diamond-like carbon (DLC) coatings as insulating and semiconducting layers in electronic components, allowing for smaller sizes and improved tribological properties, with controlled sp2/sps ratios and hydrogen content to enhance performance and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If silicon is used to construct electronic components, then electrical functionality is achieved, but the components cannot be made smaller and material stresses affect performance
Solution Approach 1:
The patent changes the material parameter from silicon to diamond-like carbon (DLC), which has different atomic size and mechanical properties. This material substitution enables smaller component sizes while reducing material stresses that affect performance stability, directly resolving the contradiction between miniaturization and reliability
Solution Approach 2:
The patent employs diamond-like carbon, a composite material with unique properties combining hardness, lubricity, and electrical insulation. This material allows for smaller component volumes while maintaining or improving performance stability through its inherent resistance to material stresses
2Manufacturing precision
If conventional coating materials are used, then insulation is provided, but the coatings are uneven and material stresses occur
Solution Approach 1:
The patent changes the coating material parameters by using diamond-like carbon with controlled sp2/sps ratios and hydrogen content. This enables uniform coating deposition with minimal material stresses, directly improving both coating uniformity and stress resistance simultaneously
3Volume of moving object
If DLC coatings are applied to reduce size, then component miniaturization is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent optimizes DLC deposition parameters including sp2/sps ratio, hydrogen content, and coating thickness to achieve miniaturization. By carefully controlling these parameters, the manufacturing process becomes manageable while achieving the desired size reduction

AI summary
Systems and methods for building passive and active electronics with diamond- like carbon (DLC) coatings are provided herein. DLC may be layered upon substrates to form various components of electronic devices. Passive components such as resistors, capacitors, and inductors may be built using DLC as a dielectric or as an insulating layer. Active components such as diodes and transistors may be built with the DLC acting substantially like a semiconductor. The amount of sp2 and sp3 bonded carbon atoms may be varied to modify the properties of the DLC for various electronic components.
