Twin Chamber Processing System Shared Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Substrate processing systems face uniformity issues and inefficiencies when processing multiple substrates in a common volume, and conventional single substrate systems fail to effectively share chamber resources, hindering cost reduction and throughput increase.
Innovation Solution
A twin chamber processing system is developed, where first and second process chambers have independent processing volumes that share resources such as vacuum pumps and gas panels, allowing for simultaneous processing of substrates while maintaining process quality by isolating and managing resource usage between chambers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple substrates are processed in a common volume, then productivity increases, but uniformity issues arise
Solution Approach 1:
The system divides the processing environment into separate process chambers (first and second chambers with first and second processing volumes), allowing multiple substrates to be processed simultaneously in isolated volumes. This segmentation maintains process uniformity for each substrate while enabling parallel processing to increase productivity.
2Manufacturing precision
If single substrate processing systems are used, then process uniformity is maintained, but resource sharing efficiency is poor
Solution Approach 1:
The system implements shared processing resources (such as gas panels, vacuum pumps, or other support systems) that serve multiple process chambers. This allows a single resource to be utilized by both the first and second chambers, improving resource utilization efficiency while each chamber maintains its own processing volume to ensure process uniformity.
3Ease of manufacture
If shared resources are used between chambers, then cost of ownership decreases, but resource allocation complexity increases
Solution Approach 1:
The system dynamically allocates shared resources between the first and second chambers based on processing needs. The shared resources can be selectively assigned to either chamber or both chambers simultaneously, allowing flexible resource management that reduces overall system cost while adapting to varying processing demands through controlled dynamic allocation.

AI summary
Methods for processing substrates in twin chamber processing systems having first and second process chambers and shared processing resources are provided herein. In some embodiments, a method may include providing a substrate to the first process chamber of the twin chamber processing system, wherein the first process chamber has a first processing volume that is independent from a second processing volume of the second process chamber; providing one or more processing resources from the shared processing resources to only the first processing volume of the first process chamber; and performing a process on the substrate in the first process chamber.
