Let´s talk!

SECS/GEM standard

The SECS/GEM is the semiconductor's equipment interface protocol for equipment-to-host data communication, one aspect of the industry 4.0 trend. The minimum GEM interface implies required data variables, status variables, equipment constants, and collection events. Additional machine-specific alarms, data variables, status variables, equipment constants and collection events are enhancing the value of any GEM interface. This included SECS-II messaging (E5), GEM (E30), and either the HSMS (E37) or RS-232 (E4) transport protocol standard.

Get in contact with us to learn how we can connect your non-300mm equipment with a SECS/GEM interface protocol.

SECS/GEM300

The introduction of 300mm wafers, with the attending demand for solutions that enabled far greater automation within the industry 4.0 development, created a whole new set of challenges. The GEM300 standards were developed by SEMI to solve these challenges.

  • EG
  • G85
  • KLA Resultfile
  • STDF
  • TEL
  • TI
  • TSK-Accretech
  • WQL
