<p>Hi Gabe,</p>
<p><br>
</p>
<p>We have a lot of AJA hardware that has been pretty good to us
over the years (various sputter/an ion mill/etc), and a few
Angstrom evaporators - we really like the Angstrom UHV loadlock
system that we have. Primarily we are using this for Ohmic
contact metals, fast cycle time, nice software, good company
support. We also have a Quantum tool from them that is doing some
nice JJ work. I want to point you towards Aaron Windsor here who
manages these tools and has run our evaporators for years - his
insights hopefully might be useful for you, adding him to this
reply. I am not sure about throwing the oxides into the mix on a
brand new tool, I would think about punting that towards older
tooling and segregating if possible.</p>
<p><br>
</p>
<p>Best,</p>
<p>C</p>

We are in the process of procuring a new E-Beam evaporator and
considering options from Kurt J. Lesker, AJA Internation, and
Angstrom Engineering; the pricing between all three vendors is
comparable. We have lots experience using and maintaining KJL
and AJA systems, but do not have much exposure to Angstrom
Engineering's systems. We are curious for other nanolabs
experience with these tools, particularly from a maintenance
prospective. We plan to use this tool for both metal and oxide
depositions. Any feedback or thoughts on Angstrom's E-beam
systems is very much appreciated! </div>
