Substrate Processing Management Device Trouble Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In substrate processing systems, identifying the trouble-occurring unit and detailing the events leading up to a trouble occurrence is challenging due to the lack of comprehensive and timely display of processing environment data in existing management devices.
Innovation Solution
A substrate processing system with a management device that includes a processing environment measuring unit, a trouble information notifying unit, and a storage unit to store and correlate measurement and notification information, allowing for the detailed display of trouble occurrence details on an operation screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the management device only displays basic trouble information (alarm ID, alarm text, trouble occurring time), then the device complexity is low, but the trouble analysis time increases and measurement precision of trouble details is insufficient
Solution Approach 1:
The management device pre-collects and stores processing environment data (temperature, pressure, gas flow rates) from various sensors in the substrate processing apparatus before troubles occur. When a trouble is detected, this pre-collected data is immediately displayed alongside the alarm information, eliminating the need for manual data collection and providing immediate contextual information for trouble analysis.
Solution Approach 2:
The management device is designed to collect, store, and display multiple types of information simultaneously - basic alarm information (alarm ID, alarm text, occurrence time) and detailed processing environment data (temperature, pressure, gas flow rates) from various sensors. This multi-functional capability allows a single device to provide comprehensive trouble analysis information without requiring additional separate systems.
2Loss of information
If the repairman manually collects trouble information from multiple sources, then the information completeness may be improved, but the time required for trouble analysis increases
Solution Approach 1:
The management device merges multiple information sources into a single integrated display. It combines basic alarm information (alarm ID, alarm text, occurrence time) with detailed processing environment data (temperature, pressure, gas flow rates) from various sensors, all in one location. This eliminates the need for repairmen to manually visit multiple sources (device controller, management device, client statements) to collect complete trouble information.
Solution Approach 2:
The system automatically feeds back processing environment data to the management device when troubles occur. Sensors continuously monitor parameters such as temperature, pressure, and gas flow rates, and this data is automatically transmitted to and displayed on the management device alongside alarm information, providing immediate feedback without manual intervention.
3Measurement precision
If detailed processing environment data is continuously monitored and displayed, then the trouble identification accuracy is improved, but the device complexity and data processing requirements increase
Solution Approach 1:
The system extracts only the essential processing environment parameters relevant to trouble analysis - specifically temperature, pressure, and gas flow rates from sensors in the substrate processing apparatus. By focusing on these key parameters rather than attempting to monitor and display all possible data, the system achieves effective trouble identification while keeping the data processing requirements manageable.
