Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If engineers use manual troubleshooting based on undependable experiences to fix semiconductor equipment failures, then they can resolve equipment issues, but they waste a lot of time and the reliability of the repair process is low
Solution Approach 1:
The system performs preliminary action by pre-processing and storing failure history data in an abnormal model classification table before actual troubleshooting occurs. The natural language processing is performed in advance on historical failure records, extracting key features and organizing them into a structured classification system that can be quickly queried during equipment failures, eliminating the need for engineers to manually analyze raw historical data each time.
Solution Approach 2:
The system creates a copied and structured representation of unstructured failure history data. By using natural language processing to extract and organize key information from historical records into a standardized abnormal model classification table, the system creates a simplified copy of the original complex data that can be efficiently searched and applied to current troubleshooting scenarios.
2Measurement precision
If engineers rely on undependable experiences to troubleshoot semiconductor equipment, then they can perform repairs, but the consistency and accuracy of repair solutions are poor
Solution Approach 1:
The abnormal model classification table serves as an intermediary between the unstructured failure history data and the engineer's decision-making process. The natural language processing system acts as a mediator that automatically extracts, standardizes, and organizes historical failure information into a structured format, eliminating the need for engineers to manually interpret unstructured data and reducing reliance on inconsistent personal experience.
Solution Approach 2:
The system transforms the parameters of failure data from unstructured natural language text into structured, standardized parameters organized by abnormal models and categories. This parameter transformation includes extracting key features, assigning classifications, and organizing data into a consistent format that enables accurate and repeatable troubleshooting across different engineers and scenarios.
