FAQ
What is SECS/GEM and what does it stand for
SECS/GEM (SEMI Equipment Communications Standard / Generic Equipment Model) defined by SEMI is the industry standard protocol for communication between semiconductor manufacturing equipment and factory host systems. It defines how machines report status, events, alarms, and process data to the factory MES. NxSphere® GEM implements the full SECS/GEM standard.
What is NxSphere® GEM and who is it for?
NxSphere® GEM is a SECS/GEM SDK and communication library designed for equipment OEMs who need to build SEMI-compliant tools. It provides .NET libraries, intelligent APIs, a visual Model Builder, and a built-in Host simulator.
What SECS/GEM communication protocol does NxSphere® GEM support?
NxSphere® GEM supports the full SECS/GEM communication protocol including SECS-II message encoding, GEM state models, HSMS (TCP/IP) and SECS-I (RS232) transport. It covers SEMI E4, E5, E30, E37, E39, and E40 standards.
Does NxSphere® GEM include a SECS/GEM simulator?
Yes. NxSphere® GEM includes a built-in SWIFT Simulator that emulates the host endpoint, allowing you to validate SECS/GEM communication instantly without needing a live factory connection.
How do I get started with SECS/GEM development?
NxSphere® GEM includes comprehensive sample programs, a Quick Start Guide, and a SECS/GEM simulator for hands-on learning. The visual Model Builder lets you configure GEM services without writing SECS/GEM protocol code. A free 30-day evaluation is available.
How do I upgrade from NxSphere® GEM to NxSphere® GEM300?
NxSphere® GEM provides a seamless upgrade path to NxSphere® GEM300 when you need to meet 300mm fab requirements. The API is designed for forward compatibility, minimising migration effort.
