To All,

 The turbo pump for the Lampoly tool is bad, it shutdown
itself when at high rpm speed. I will call the repair house
tomorrow morning and will update again on how long it will take to
repair the turbo pump. Sorry for the inconvenience.


Cesar

To All,

  The turbo pump is going out for repair and it will take
 two weeks to repair the pump.

I just received an update from the pump repair shop (Provac).  They said 
that the turbo pump that we sent them is unrepairable.  They do however 
have a direct replacement pump in stock.  They will send me a quote 
tomorrow.

I have received two quotes for the Seiko-Seiki turbo pump for about 
$23,000 and they have the pump in stock.  However; according to the pump 
rebuilder (Provac), the turbo that the Lam etcher is using has a 
levitator reliability problem.  They said that in the event of a turbo 
crash, the levitor assembly is susceptible to heavy damage which can 
renders it unrepairable.  As a result, we are looking into the 
possiblity of using a different, more reliable pump.  We are trying to 
expedite this process but the main issue that needs to be resolved is 
the interfacing between the turbo controller and the Lam system.  
Alcatel has a turbo pump with an interface convertion kit.  I will try 
to get  more information on this tomorrow.

We have a turbo pump in-house that is more reliable than the turbo that 
we've removed.  We believe that we have figured out how to interface the 
turbo's controller with the Lam.  There are however; hardware issues 
involved with physically mounting it on the system.  But right now there 
are no show stoppers.  We should be ready to test it by noon on Friday.

Hi Elmer,
   
  Excellent work on both P5000 and Lam Poly.  We know you can get these things running.

The Good news:
    Installed new turbo on the system.  Currently in the process of 
reconnecting the water lines, the foreline and the purge line.  Still 
need to install the controller .

The Bad news:
    The system was powered down last night because of a significant 
water leak coming from area around the RF matching network.  I will 
evaluate the damage next week.

Finalizing the installation of the new turbo. It has taken longer than 
anticipated because the turbo support brackets had to be redesigned and 
new purge lines had  to be welded.   Installation should be completed by 
Friday.  I will then repair the water leak and then power up the system 
on Monday 7/3.
