[Bnc-facility-notice] UltraPure Water System Down

[Voorhis, Mark L.]

Dear Birck Users,

The UPW system is operational and all building ambient conditions are back to normal.  BRK engineering quickly responded to evaluate, and address needed repairs to critical components for the ultra-pure water system.  The ultra-pure water quality is not meeting specification but should improve over time.

Thank you for your patience during this ultra-pure water interruption.

Regards,

Dear Birck Users,

The UPW experienced a significant leak in one of the de-gas membrane housings and leaked water onto the subfab floor.  The system is totally shut down until engineering can evaluate the situation and provide the appropriate recovery.  Humidification of the cleanroom uses UPW but with current weather conditions we don't believe this will be a significant issue.

We will keep you notified of progress, but it may be down until at least Monday afternoon and perhaps beyond that.

Thank you for your patience as we work through this issue.

Ron
