Factory Interface Partition Design for Redundant Substrate Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device manufacturing systems face downtime and reduced yield due to component failures, necessitating a shutdown of the entire system for maintenance, which increases costs and reduces throughput.
Innovation Solution
A factory interface is divided into multiple independent subsystems, each with its own sealed environment and utility systems, allowing for one subsystem to remain operational during maintenance of another, thereby facilitating redundancy and continuous manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the factory interface is divided into multiple independent subsystems with separate sealed environments, then system reliability is improved through redundancy, but device complexity increases due to multiple partitions and sealed environments
Solution Approach 1:
The factory interface is divided into multiple independent subsystems (first factory interface subsystem and second factory interface subsystem) separated by a partition. Each subsystem has its own sealed environment, factory interface robot, and utility systems, allowing independent operation and maintenance. This segmentation enables redundancy where one subsystem can continue operating while another undergoes maintenance, directly improving system reliability.
2Ease of repair
If the entire manufacturing system is shut down for maintenance of a single component, then ease of repair is improved, but productivity decreases due to complete system downtime
Solution Approach 1:
The system is segmented into independent subsystems that can be maintained separately. When one subsystem requires maintenance, only that specific subsystem is shut down while other subsystems continue to process substrates. This eliminates the need to shut down the entire manufacturing system for single component repairs, maintaining productivity while enabling ease of repair.
Solution Approach 2:
The independent subsystems enable continuous operation of the manufacturing system. While one subsystem is undergoing maintenance, the other subsystem(s) continue to transfer and process substrates without interruption. This continuity of useful action ensures that productivity is maintained despite ongoing maintenance activities in other parts of the system.
3Loss of time
If multiple independent subsystems are implemented with separate utility lines, then loss of time is reduced by avoiding complete system shutdowns, but device complexity increases due to multiple utility lines and sealed environments
Solution Approach 1:
The factory interface is segmented into independent subsystems with separate utility lines (air utility lines, vacuum utility lines) for each subsystem. This segmentation allows maintenance to be performed on one subsystem without affecting others, reducing the loss of time for the overall system. Each subsystem's independence means utility failures or maintenance in one area do not propagate to other areas.

AI summary
A substrate processing system for an electronic device manufacturing system can include a factory interface forming an interior volume, and a partition disposed in the factory interface. The partition can divide the interior volume into a first factory interface chamber forming a second interior volume, and a second factory interface chamber forming a third interior volume. The partition can be configured to provide a first sealed environment in the first factory interface chamber and a second sealed environment in the second factory interface chamber.
