Adaptive Wiring Layout for Microlithography Component Offsets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Microlithography systems face challenges in accurately placing components within defined areas, leading to misalignment and inefficiencies in wiring placement, which results in out-of-specification components and reduced economic viability, necessitating adaptive solutions for precise and rapid processing.
Innovation Solution
The method involves obtaining coordinate data on components, scanning them to determine offsets from designed states, and augmenting connection patterns based on these offsets to ensure accurate wiring connections, allowing for slight deviations and adaptive processing in microlithography systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If fixed static wiring connections are used from periphery to component, then wiring placement precision is improved, but component placement flexibility deteriorates
Solution Approach 1:
The patent transforms the fixed static wiring connection approach into a dynamic adaptive system. The wiring pattern is no longer predetermined but is dynamically generated based on the actual measured component position. The system adjusts the wiring layout in real-time to accommodate component placement variations, thereby maintaining wiring precision while enabling placement flexibility.
Solution Approach 2:
The patent changes the parameters of the wiring connection system from fixed to variable. By measuring the actual component position and using this data to generate the wiring pattern, the system adapts its parameters (wiring routes, connection points) based on actual conditions, resolving the contradiction between precision and flexibility.
2Manufacturing precision
If strict component placement control is implemented, then misalignment is reduced, but processing complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the actual component position is measured and this information is fed back into the system to generate the appropriate wiring pattern. This feedback loop eliminates the need for strict preventive control measures, as the system naturally compensates for placement variations, reducing processing complexity while maintaining alignment accuracy.
Solution Approach 2:
The system performs self-adjustment by automatically measuring component position and generating corresponding wiring patterns without requiring external intervention or complex control mechanisms. The measurement and adaptation process is integrated into the workflow, simplifying the overall processing while ensuring accuracy.
3Productivity
If maskless microlithography is used for rapid processing, then processing speed is improved, but alignment precision deteriorates
Solution Approach 1:
The patent performs preliminary measurement of the component position before generating the wiring pattern. This preliminary action captures the actual component location, allowing the subsequent maskless microlithography process to proceed rapidly while maintaining precision through the use of measured data for pattern generation.
