Silane Briefing (April 15, 2010 in San Jose)
Silane Briefing – Incidents & Standards Update (April 15, 2010 in San Jose)
Date and Location
Thursday, April 15, 2010, 9:00 – 11:30 AM
SEMI Headquarters, 3081 Zanker Road, San Jose, CA 95134, USA
The Briefing is presented by Chemically Speaking, LLC.
The Briefing is hosted by the SEMI EHS Division.
Silane, (Silicon Tetrahydride) is an electronic specialty gas that has had widespread use in the semiconductor fabrication industry since the mid 1960’s when the first Integrated Circuit (IC) manufacturers began operations. In those early days there was little information available on the safe handling of silane or its behavior when released. Numerous incidents involving fire and explosions occurred during use, handling, transportation and manufacturing. During this time considerable study was conducted to better understand silane properties.
In the last ten years, LCD and PV manufacturers who are also silane users have grown dramatically and use of silane is expected to more than double in the next 5 years. While silane is a high pressure pyrophoric gas, it does not always immediately ignite when released. The reason for this is not fully understood despite 40 years of research. This behavior has been the cause of some significant incidents including two fatal silane accidents in 2005 and 2007 in photovoltaic manufacturing facilities, and numerous fires and explosions as recently as September, 2009.
This briefing will provide an update on silane incidents and the status on silane standards revision of ANSI/CGA G13 and SEMI S18. G13 which has become the worldwide safety standard for silane is undergoing a revision that can significantly change the setback distances. Considerable work is being done to redo the Fault Tree and to look at 20 years of industry experience with bulk silane.
Through a review of past and present incidents, potential root causes and how silane behaved in the incident, improved safety in the design and operation of systems as well as improvement in response procedures to an incident can be achieved. New silane users continue to have large and small incidents, due to system design, installation and/or operation. This briefing will also review an actual emergency response to a silane fire in a gas cabinet, captured by a robot video camera.
