Engineering Contradiction Analysis
1Reliability
If device miniaturization progresses and more monitoring functions are added to the apparatus side, then the ability to self-monitor and detect abnormalities improves, but the device complexity and manufacturer's load increase
Solution Approach 1:
The substrate processing apparatus autonomously performs self-diagnosis and self-monitoring by integrating a device state monitoring control part that automatically collects device data, analyzes operational states, and detects abnormalities without requiring external manufacturer intervention. The system serves itself by generating maintenance timing information and stability evaluation data internally.
Solution Approach 2:
The device management controller is designed to perform multiple functions simultaneously: it monitors parts state, tracks device data integrity, evaluates facility data, and generates comprehensive stability assessments. This multi-functional approach consolidates various monitoring tasks into a single integrated system, avoiding the need for separate complex monitoring subsystems.
2Measurement precision
If comprehensive monitoring of parts, device data, and facility data is implemented, then the accuracy of operation state evaluation improves, but the data processing load and system complexity increase
Solution Approach 1:
The monitoring system is divided into distinct functional modules: a parts management control part for monitoring parts state, a device state monitoring control part for analyzing device data, and a data matching control part for evaluating facility data. Each module processes specific data types independently, then integrates results to achieve comprehensive evaluation without overwhelming complexity.
Solution Approach 2:
The system continuously collects device data, compares it against reference values and historical patterns, and uses this feedback to dynamically adjust monitoring thresholds and generate real-time stability evaluations. This feedback mechanism enables accurate operation state assessment through iterative analysis rather than complex static processing.
