ST. PETERS, Mo., March 15, 2011 /PRNewswire/ -- MEMC Electronic Materials, Inc. (NYSE: WFR) today provided an update on the status of its employees and facility in Utsunomiya, Japan following the 9.0 magnitude earthquake that occurred on March 11.  

MEMC employees at the Utsunomiya facility, which is approximately 130 miles from Sendai, were safely evacuated following the earthquake, and no injuries were reported. Operations at the facility remain suspended pending the conclusion of building and equipment safety inspections and an analysis of potential damage. As a result, MEMC expects that shipments from this facility will be delayed over the near term.

MEMC has a network of 12 manufacturing facilities around the world. The Utsunomiya facility is one of eight that manufacture semiconductor wafers, and one of three that engages in the slicing and polishing ("wafering") of 300 millimeter (mm) wafers for the semiconductor industry. The facility also engages in wafering a small volume of 200mm wafers.  The facility does not grow the semiconductor crystals for which it provides wafering.  

The company is currently conducting inspections and assessing the impact to production and shipments from the Utsunomiya facility, and expects to provide additional updates as information becomes available.
