In April, the suite of SEMI software standards commonly referred to as "Interface A" turned 5 years old.

Coincidentally, also in April, the SEMI standards North America Information and Control Committee approved an important revision to these standards to incorporate many of the lessons learned from early implementations.

SEMATECH, through its subsidiary ISMI, for years has been consistent in communicating how important Interface A (a.k.a. - Equipment Data Acquisition - EDA) is to the current and future manufacturing automation needs of its member companies. This message was repeated again at an ISMI workshop I attended this last Spring. ISMI had explained that the SEMATECH member companies (which make up 50 percent of the worldwide chip market) wanted ISMI to focus on a smaller number of projects with short-term benefits for 2009. Interface A (EDA) is on this short list.

In support of the ISMI members' vision for a better quality data communication interface, Cimetrix has been actively developing Interface A software since before the standards were published with early prototypes based on draft documents back in 2002-2003. We have had a continuous product improvement program in place since 2004 for our CIMPortal product which implements the Equipment Data Acquisition standards on the server side. We had previews of our EDAConnect factory-side EDA product at SEMICONWest 2007 and launched the product later that year.

So, as I was sitting in the workshop listening to the speaker from ISMI say once again what an important enabling technology Interface A was for current and Next Generation Factories (NGF), I thought to myself, "I keep hearing ‘we need it, we need it'. I wonder why more companies aren't using it"?

Why do you think companies have been slow to deliver Interface A (EDA) solutions on their equipment and using it in their fabs?
