Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing carrier arrangements for microsystems are complex and limited in terms of geometric configuration, functional properties, compactness, temperature resistance, and chemical stability.
Innovation Solution
A production method that involves producing at least one layer on a carrier surface, with the layer having a first region on the carrier and a second region that can be detached from the carrier, allowing for flexible and compact carrier arrangements with improved temperature resistance and chemical stability.

Engineering Contradiction Analysis
1Manufacturing precision
If conventional rigid-flex composite technology is used with flexible foils and conductor tracks, then carrier arrangements can be produced with connecting lines, but the conductor track widths are limited to at least 50 μm and geometric configuration is restricted
Solution Approach 1:
The patent changes the fundamental parameters of the carrier arrangement by using thin-film technology deposited directly on rigid carriers, enabling conductor track widths in the micrometer and sub-micrometer range instead of the 50 μm minimum in conventional rigid-flex technology. This parameter change in track width enables entirely new geometric configurations and microsystem applications.
2Strength
If adhesive bonding is used to attach carrier components, then mechanical connection is achieved, but temperature stability is limited due to adhesive constraints
Solution Approach 1:
The patent extracts and eliminates the adhesive layer from the carrier arrangement structure. By using direct thin-film deposition and bonding techniques on rigid carriers, the invention removes the temperature-limiting adhesive component while maintaining mechanical connection through alternative methods such as laser bonding or direct metallization, thereby achieving superior temperature stability.
3Reliability
If complex production processes with multiple steps are used, then functional properties can be achieved, but production complexity and time increase
Solution Approach 1:
The patent merges multiple production steps into integrated thin-film deposition and patterning processes. By combining conductor track formation, insulation layer application, and component bonding into a unified thin-film fabrication sequence on rigid carriers, the invention reduces production complexity while maintaining all necessary functional properties for microsystem applications.
