[labnetwork] Experience with Angstrom E-Beam Evaporators?

[Christopher Alpha]

Hi Gabe,


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.


Best,

C
