Machine interfacing

Products of SPA do support highly compatible interfaces in order to enable performant communication between equipment of the probe floor and its managing instances. PVA SPA offers powerful standalone solutions as well as smart integrated solutions for adapting the equipment in a corresponding network. Our key expertise focuses on both protocols, SECS/GEM and SECS/GEM300 for processing any wafer diameters from 2“ to 12“ as well as other i.e. tray based material fluently and serves broad band communication and reliable conversion of production data.

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.


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.
