In the semiconductor manufacturing industry, seamless communication between equipment and host systems is crucial for maintaining high productivity and quality. The SECS/GEM (SEMI Equipment Communication Standard/Generic Equipment Model) protocol is a widely adopted standard that facilitates this communication. In this blog, we will delve into the implementation of SECS/GEM on the KLA-Tencor 7700 Surfscan, using the EIGEMBox as the interface.

Understanding SECS/GEM Protocol

What is SECS/GEM?

SECS/GEM is a set of standards developed by SEMI (Semiconductor Equipment and Materials International) to enable standardized communication between semiconductor equipment and factory host systems. SECS (SEMI Equipment Communication Standard) defines the messages and protocols used for communication, while GEM (Generic Equipment Model) specifies the standard behaviors for equipment.

Benefits of SECS/GEM

Standardization: Provides a uniform communication interface across different equipment and manufacturers.

Automation: Enables automated control and monitoring of equipment, leading to higher efficiency.

Data Collection: Facilitates the collection and analysis of equipment data, improving process control and decision-making.

Overview of KLA-Tencor 7700 Surfscan

The KLA-Tencor 7700 Surfscan is a high-precision surface measurement tool used in semiconductor manufacturing. It is designed to detect and measure surface defects and particles on wafers, ensuring the highest quality in the production process. Implementing SECS/GEM on this equipment enhances its functionality by allowing it to communicate effectively with the factory host system.

The Role of EIGEMBox

The EIGEMBox is an intelligent interface device that facilitates SECS/GEM communication between semiconductor equipment and host systems. It acts as a bridge, translating the equipment's proprietary protocols into SECS/GEM standards, ensuring seamless integration and communication.

Step 1: Setting Up the EIGEMBox

To begin, you need to set up the EIGEMBox. This involves configuring the device to communicate with both the KLA-Tencor 7700 Surfscan and the host system.

Connect the EIGEMBox to the KLA-Tencor 7700 Surfscan: Use the appropriate communication ports and cables to establish a physical connection between the EIGEMBox and the Surfscan.

Power On and Configure Network Settings: Power on the EIGEMBox and configure its network settings to ensure it can communicate over your factory network.

Install Necessary Software: Install any required drivers or software on the EIGEMBox to enable it to interpret the Surfscan's proprietary protocols.

Step 2: Configuring SECS/GEM Communication

Once the EIGEMBox is set up, the next step is to configure the SECS/GEM communication parameters.

Define Communication Parameters: Configure the SECS/GEM communication parameters such as device ID, communication port, and baud rate to match the settings on the Surfscan.

Establish Communication Protocol: Set up the communication protocol to define how messages will be exchanged between the Surfscan and the host system.

Step 3: Implementing SECS Messages

Implement the necessary SECS messages to facilitate communication. This involves defining the message structure and content that will be exchanged between the Surfscan and the host.

Stream and Function Codes: Define the stream and function codes for different types of messages such as status inquiries, data collection, and control commands.

Data Items: Specify the data items to be included in the messages, such as measurement results, equipment status, and error codes.

Step 4: Testing and Validation

After configuring the SECS/GEM communication, it is crucial to test and validate the setup to ensure everything is working correctly.

Conduct Communication Tests: Perform tests to ensure that messages are being correctly transmitted and received between the Surfscan and the host system.

Validate Data Integrity: Verify that the data being exchanged is accurate and consistent with the expected values.

Monitor Performance: Monitor the communication performance to ensure there are no delays or errors in the message exchange.

Benefits of SECS/GEM Implementation on KLA-Tencor 7700 Surfscan

Enhanced Automation

Implementing SECS/GEM on the KLA-Tencor 7700 Surfscan enables enhanced automation of the equipment. This allows for automated data collection, real-time monitoring, and control, reducing the need for manual intervention and increasing operational efficiency.

Improved Data Accuracy

With SECS/GEM, the data collected from the Surfscan is transmitted in a standardized format, ensuring consistency and accuracy. This improves the reliability of the data used for process control and decision-making.

Increased Equipment Uptime

By enabling automated monitoring and control, SECS/GEM helps in identifying and addressing potential issues before they lead to equipment downtime. This proactive approach increases the overall uptime of the Surfscan, leading to higher productivity.

Conclusion

Implementing SECS/GEM on the KLA-Tencor 7700 Surfscan through the EIGEMBox offers numerous benefits, including enhanced automation, improved data accuracy, and increased equipment uptime. This integration ensures seamless communication between the Surfscan and the factory host system, optimizing the overall manufacturing process.
