The GEM300 SDK is a comprehensive software development kit designed to support EIGEM300 equipment integration and automation in semiconductor fabs. Built to meet SECS GEM 300 communication requirements, the GEM300 software ensures seamless tool-to-host connectivity and reliable factory automation. By implementing the standardized GEM300 protocol, equipment manufacturers can achieve full GEM300 compliance while reducing integration complexity. Supporting both the 300mm SEMI Standard and the broader 300mm Standard, the GEM300 SDK enables faster development, easier deployment, and consistent performance across semiconductor tools. Whether for new equipment design or upgrading existing systems, this solution provides a robust framework for SECS/GEM 300mm integration, GEM300 protocol implementation, and advanced automation in next-generation wafer fabs.
