Mark's note reminded me that I also have a precursor foreline trap
(Mass-Vac 355063).<br>

<p class="MsoNormal">Hi Mac,<br>
<br>
Our FlexAL came with an Adixen ADS 602P four years ago. At
some point the service engineer had to adjust a breaker inside
the tool's power box to allow the pump to draw more current at
startup.<br>
<br>
Cheers,<br>

<p class="MsoNormal" style="margin-bottom:12.0pt">Hello Folks,<br>
<br>
I'm wondering: how many of you have tried a dry pump on your
ALD system?<br>
<br>
If you have, how did it work out?<br>
<br>
If you could supply the following details, that would be
great:<br>
<br>
ALD system model;<br>
<br>
Dry pump model and CFM;<br>
<br>
How long it's been running that way;<br>
<br>
Any issues you've run in to.<br>
<br>
For background, we have long been working under the
assumption that, due to the reactive nature of the ALD
precursors, and the abrasive nature of the effluent,
PFPE-base wet pumps are the way to go. However, we grow
tired of dealing with pump oil and associated issues, and
we're using dry pumps successfully elsewhere in the fab...<br>
<br>
Thanks!<br>
<br>
Mac<br>
