Semiconductor Tool Terminal Coordination With Shared Login Messaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In semiconductor manufacturing systems, simultaneous multi-user access and communication between local and remote operation terminals are challenging due to the need for maintaining a clean environment, limiting direct communication and causing potential operational conflicts and lack of real-time collaboration.
Innovation Solution
A control device with a login state management unit and communication unit enables simultaneous login and message posting/browsing between local and remote operation terminals, allowing for independent apparatus screens and chat functionality to facilitate smooth communication between users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple users access the semiconductor manufacturing apparatus simultaneously through local and remote terminals, then collaboration efficiency is improved, but operational conflicts and system reliability deteriorate
Solution Approach 1:
The control device monitors the login states of multiple terminals in real-time and provides feedback by notifying users of current access status. When a user logs in through a remote terminal, the system detects this state and sends notifications to other connected terminals, enabling users to coordinate their actions and avoid operational conflicts while maintaining simultaneous access.
Solution Approach 2:
The control device acts as an intermediary between multiple operation terminals. It manages the login states of all terminals and coordinates communication between users, mediating access requests and operational actions to prevent conflicts while enabling collaboration across local and remote terminals.
2Object-affected harmful factors
If direct communication between local and remote terminals is limited to maintain clean room environment, then environmental control is improved, but communication efficiency deteriorates
Solution Approach 1:
The control device serves as an intermediary communication hub that enables message exchange between local and remote terminals without requiring direct physical communication. Users can post and browse messages through the control device, which transmits information digitally while maintaining the physical barrier of the clean room environment.
Solution Approach 2:
The system replaces direct physical communication mechanisms with electronic message transmission. Instead of requiring physical presence or direct terminal-to-terminal communication, users exchange information through digital messages transmitted via the control device, eliminating the need for physical interaction while maintaining communication efficiency.

AI summary
A control device for controlling a semiconductor manufacturing apparatus including a local operation terminal displaying an apparatus screen of the semiconductor manufacturing apparatus and one or more remote operation terminals displaying the apparatus screen, includes: a login state management unit that manages the local operation terminal and at least one of the remote operation terminals that are logged into the same semiconductor manufacturing apparatus; and a communication unit that provides a function of posting and browsing a message between a first user operating the local operation terminal and a second user operating the at least one of the remote operation terminals that are logged into the same semiconductor manufacturing apparatus, by transmitting screen data enabling the posting and browsing of the message to the local operation terminal and the at least one of the remote operation terminals that are logged into the same semiconductor manufacturing apparatus.
