editWhile looking for information on this subject I happened across a web site where I was struck by the similarities between the language used in that article and this page.
For example, this text:
- The Generic Model For Communications and Control Of Manufacturing Equipment (GEM) standard is maintained and published by the non-profit organization Semiconductor Equipment and Materials International (SEMI). Generally speaking, the GEM standard defines messages, state machines and scenarios to enable factory software to control and monitor manufacturing equipment. The GEM standard is formally designated and referred to as SEMI standard E30, but frequently simply referred to as the GEM or SECS/GEM standard. GEM intends "to produce economic benefits for both device manufacturers and equipment suppliers..." by defining "... a common set of equipment behavior and communications capabilities that provide the to support the manufacturing automation programs of semiconductor device manufacturers" [SEMI E30, 1.3]. GEM is a standard implementation of the SECS-II standard, SEMI standard E5. Many equipment in semiconductor (front end and back end), surface mount technology, electronics assembly, photovoltaic, flat panel display and other manufacturing industries worldwide provide a SECS/GEM interface on the manufacturing equipment so that the factory host software can communicate with the machine for monitoring and/or controlling purposes. Because the GEM standard was written with very few semiconductor-specific features, it can be applied to virtually any manufacturing equipment in any industry.
is more or less identical to the article, and indeed the entire article seems to come from the Squidoo web page on secsgem.
I thought the aim of Wikipedia was not to copy directly the content of other web pages. In this case the content is entirely relevant to the subject, though I think the whole area (SECS/GEM and SECS-II) needs attention to bring it up to a reasonable standard.
