Cancelling my reservation for this evening 4 - 12 midnight. Process problem using ZEP - 520...

[James Conway]

Greetings RAITH Users:

I am canceling my session after my wafers did not spin up uniformly 
using ZEP-520-12.

I am using ZEP - 520 - 12 and was surprised to have this result after 
many runs with no problems.
Other users working with this bottle of resist since 9-14-2004 are 
requested to send me a brief email and tell me if their wafers spun up 
uniformly or not?  Thickness measurements?

This problem is the same or similar to what Arvind reported several 
weeks ago.  The wafers under microscope inspection at any magnification 
look like a psychedelic light show.

I will strip and repeat tomorrow morning for tomorrow afternoon.

System is available for the next user...
