Unveiling SECS/GEM: Enhancing Communication in Semiconductor Manufacturing


In the intricate world of semiconductor manufacturing, communication is key to ensuring the seamless operation of equipment and processes. SECS/GEM, which stands for Semiconductor Equipment Communication Standard/Generic Equipment Model, plays a pivotal role in facilitating communication between semiconductor equipment and host systems. Developed by the Semiconductor Equipment and Materials International (SEMI), SECS/GEM has become a widely adopted standard, contributing to the efficiency and reliability of semiconductor manufacturing.

This blog will delve into SECS/GEM and discuss how to leverage its power through a real-world example.

Understanding SECS/GEM

SECS/GEM serves as a communication standard that defines the protocol and message formats for communication between manufacturing equipment and host systems. It provides a common language that enables different equipment and systems from various manufacturers to communicate effectively, fostering interoperability and standardization in the semiconductor manufacturing environment.

SECS-II Protocol

SECS/GEM relies on the SECS-II (SEMI Equipment Communications Standard 2) protocol, defining the rules for message formatting, communication initiation, and data encoding. This protocol ensures that data exchanged between equipment and host systems is consistent and easily interpretable.

HSMS (High-Speed Message Service)

SECS/GEM often utilizes HSMS for communication, allowing for fast and reliable data transfer between equipment and host systems. HSMS is a communication protocol that operates over various physical layers, such as TCP/IP, enabling flexibility in implementation.

Equipment Constants and Variables

SECS/GEM defines a set of standard equipment constants and variables that provide a common framework for describing equipment status, events, and capabilities. This ensures that equipment from different manufacturers can be easily integrated into a manufacturing environment without the need for extensive customization.

Harnessing SECS/GEM: A Real-World Example
