Fellow Nitride Users,

As many of you are aware, we have been trying to track down the cause of 
the increase in particles or bubbles in the flims recently deposited in 
the system.  At this point we have had some success with adding a one 
hour ammonia purge before deposition.  But we need further confirmation 
that this purge is helping.  We'd like to do that without tying up the 
furnace and keeping you from getting your work done.

In order to test this out we appeal to you for your help.  Will you 
please add a blank test wafer to your runs and give it to us with the 
following information; Program name, date and deposition time.

If you'd like to try out the programs which have the extended NH3 purge 
(and we hope you do) the are on the disk called NITR2LONG (a form of 
NITRIDE2) and 378LONG (adjusted LONH378).

Thanks you in advance for all your help,

			Nancy and Maurice
