• As we talk about SEMI, SECS and GEM. Firstly let
  us understand what these acronyms are.
• SECS refers to Semi Conductor Equipment
  Communication Standard, GEM refers to Generic
  Equipment Model for Communications and Control of
  Manufacturing Equipment and SEMI stands for
  Semiconductor Equipment Materials Initiative.
• Semiconductor Equipment Materials Initiative (
  SEMI ) developed a set of standards called
  SECS/GEM. These standards are used to define a
  set of communication protocols between automated
  equipment and the hosts.

SEMI standards came into existence somewhere in
1970s. The idea behind introduction of such a
standard was to support the small but blooming
semiconductor industry. SEMI brought a standard
in communication protocol between various
semiconductor equipment and fab hosts. This
eliminated the need for the communication
specification that were equipment or fab host
specific. In that way, these standards are
similar to how TCP/IP protocol is defined for
network communication or how RS232 is defined for
serial communication.

Earlier there was no standard process to handle
the communication between a semiconductor
equipment and a fab host. This used to lead in
high cost and low performance in semiconductors
industry. So this created a need for standard
process to tackle this situation. Thats where
the SEMI standards for SECS/GEM came into
existence. More details
