Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing substrate processing systems face inefficiencies in manufacturing time and inspection processes due to the lack of independent control and drive systems for each processing unit, leading to prolonged assembly and inspection times.
Innovation Solution
The implementation of a substrate processing system with multiple assemblies, each comprising a substrate processing apparatus, a fluid supply control apparatus with dedicated fluid control devices, and a drive equipment apparatus, allowing for independent operation and inspection of each unit, enabling concurrent assembly and inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple liquid processing units are incorporated in one housing with shared fluid control devices, then device complexity is reduced, but manufacturing time and inspection time are prolonged
Solution Approach 1:
The system divides the substrate processing apparatus into multiple independent assemblies, where each assembly includes a liquid processing unit with its own dedicated fluid control device and drive device. This segmentation allows each assembly to be manufactured and inspected independently, significantly reducing total manufacturing time while maintaining structural organization through the modular assembly architecture.
2Ease of manufacture
If multiple liquid processing units share common fluid supply lines and control devices, then ease of manufacture is improved, but inspection efficiency deteriorates
Solution Approach 1:
Each liquid processing unit is equipped with its own dedicated fluid control device and drive device, creating independent functional assemblies. This segmentation enables parallel inspection of multiple assemblies simultaneously, dramatically improving inspection efficiency while maintaining ease of manufacture through standardized modular assembly procedures.
Solution Approach 2:
The system performs preliminary assembly of complete functional units (liquid processing unit + fluid control device + drive device) before final integration. This preliminary assembly allows inspection to be conducted at the assembly level before system integration, enabling early detection of defects and reducing rework in later stages.
3Productivity
If dedicated fluid control devices are provided for each liquid processing unit, then inspection efficiency is improved, but device complexity increases
Solution Approach 1:
The control system is segmented into independent control units, with each liquid processing unit having its own dedicated fluid control device. This segmentation isolates control functions, making it easier to inspect and diagnose individual units without interference from other systems, thereby improving inspection efficiency while organizing complexity into manageable modular units.
4Manufacturing precision
If assemblies are assembled and inspected sequentially, then manufacturing precision is maintained, but manufacturing time increases
Solution Approach 1:
The manufacturing process is segmented into independent assembly lines, where multiple assemblies can be manufactured and inspected simultaneously in parallel. Each assembly maintains its own quality control standards, ensuring manufacturing precision is preserved while dramatically reducing total manufacturing time through concurrent production.
Solution Approach 2:
Complete assemblies are preliminarily formed and inspected as independent units before final system integration. This preliminary inspection ensures quality requirements are met at the assembly level, allowing parallel manufacturing of multiple assemblies without compromising overall system precision.

AI summary
A substrate processing system includes multiple assemblies framed and including such that each of the assemblies includes a substrate processing apparatus which supplies a processing fluid to a substrate and processes the substrate, a fluid supply control apparatus including a fluid control device which controls flow of the processing fluid supplied to the substrate processing apparatus, and a drive equipment apparatus including a drive device which drives movement of the fluid control device in the fluid supply control apparatus.
