Solution Overview
Problem
Current semiconductor fabrication faces challenges in manufacturing smaller, faster, and higher-density devices with lower costs, as existing substrates require separate designs for different circuit configurations, leading to increased costs and reduced flexibility in meeting diverse device demands.
Innovation Solution
A substrate with a selectable circuit placement mechanism that supports multiple circuit configurations through an etch back process, allowing for the adaptation of shared electrical connections to specific configurations by etching back different feature groupings, enabling the production of various device designs on a common substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate substrate designs are used for different circuit configurations, then device reliability is improved, but manufacturing cost increases and flexibility decreases
Solution Approach 1:
The substrate is designed with multiple sets of connection locations (first set, second set, third set) that can be selectively activated through the etch back mechanism. This universal substrate can support multiple circuit configurations (first configuration, second configuration, third configuration) without requiring separate substrate designs, thereby reducing manufacturing costs while maintaining reliability through proper electrical connections.
Solution Approach 2:
The substrate incorporates an etch back mechanism that dynamically reconfigures electrical connections by selectively removing insulating material. This allows the same substrate to adapt its electrical topology based on the desired circuit configuration, providing flexibility in meeting diverse device demands without compromising connection integrity.
2Manufacturing precision
If separate substrate designs are used for different circuit configurations, then circuit design precision is improved, but design cycle time increases
Solution Approach 1:
The substrate is pre-designed with multiple sets of connection locations and routing paths that are all present but inactive. The etch back mechanism selectively activates the appropriate connections for the desired configuration. This preliminary preparation allows rapid reconfiguration without redesigning the entire substrate, significantly reducing design cycle time while maintaining circuit precision.
3Adaptability or versatility
If a common substrate supports multiple configurations, then manufacturing flexibility is improved, but electrical connection reliability may worsen
Solution Approach 1:
The substrate divides electrical connections into separate, isolated sets (first set, second set, third set) with dedicated routing paths for each configuration. The etch back mechanism selectively activates one configuration at a time by removing insulating material to expose the appropriate connection set. This segmentation ensures that active connections maintain full reliability while keeping alternative connections isolated and inactive.

AI summary
An apparatus includes selectable a circuit placement mechanism configured to support two or more different circuit layouts. The circuit placement mechanism may include an overlap of electrical connections associated with the two or more circuit layouts and joined through an etch back selector. The etch back selector may enable the apparatus to function according to a selected one of the two or more different circuit layouts.
