Adhesion-Differentiated Carrier for IC Substrate Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for manufacturing IC integrated substrates are complex and costly, particularly in separating the substrate from the carrier while maintaining size stability and high precision, as they often require tedious processes like solvent use or laser ablation.
Innovation Solution
An adhesion-differentiating process is applied to create a specific area with stronger adhesion between the carrier and the IC integrated substrate, allowing for easy and low-cost separation by differentiating the interface adhesion, enabling natural separation with minimal external force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional separation methods (solvent or laser ablation) are used to separate the IC integrated substrate from the carrier, then separation can be achieved, but the manufacturing process becomes complex and costly
Solution Approach 1:
The adhesion-differentiating process is performed in advance during carrier preparation, creating regions with different adhesion strengths before the IC integrated substrate is formed. This preliminary differentiation of adhesion properties allows for simplified subsequent separation without requiring complex solvent or laser ablation processes, while maintaining size accuracy throughout manufacturing
Solution Approach 2:
The carrier is treated to create specific areas with differentiated adhesion characteristics - some regions have strong adhesion to hold the substrate during manufacturing, while other regions have weak adhesion to enable easy separation. This local quality differentiation resolves the contradiction by allowing both precise manufacturing and simple separation through spatially varying adhesion properties
2Stability of the object's composition
If strong adhesion is used between carrier and IC integrated substrate, then size stability is maintained during manufacturing, but separation becomes difficult and requires complex processes
Solution Approach 1:
The carrier surface is modified to exhibit spatially varying adhesion properties - certain regions possess strong adhesion to maintain size stability during IC integrated substrate manufacturing, while other regions have weak adhesion that facilitates easy separation. This local differentiation resolves the contradiction between maintaining stability and enabling easy separation
3Ease of manufacture
If weak adhesion is used between carrier and IC integrated substrate, then separation becomes easy, but size stability during manufacturing is compromised
Solution Approach 1:
The carrier is engineered with heterogeneous adhesion characteristics across its surface - specific regions provide strong adhesion to ensure size stability during the manufacturing process, while other regions provide weak adhesion for easy separation. This spatial differentiation of adhesion quality simultaneously achieves both manufacturing stability and separation ease
4Stability of the object's composition
If conventional rigid carriers are used, then size stability is achieved, but the IC integrated substrate lacks flexibility and cannot accommodate bending designs
Solution Approach 1:
The invention replaces conventional rigid carriers with flexible thin-film carriers that can be bent and conform to special structural requirements. These flexible carriers maintain sufficient size stability for precise IC integrated substrate manufacturing while enabling bending designs and accommodating special size limitations in the final electronic devices
