[labnetwork] Sputter Coating Equipment

[Gupta, Su]

Hi Anand:

I haved been in the sputter coating industry for over twenty years prior to moving to academia in 2004. I agree with Tom the AJA is your best best -- they are dominating the R&D market right now. I have an SFI Shamrock seven-gun tool -- it is exceptional for my GNR/TMR needs, but for more general purposes I would recommend AJA. Also SFI has been out of business for many years now, and it is difficult finding support for the tools.

All the best,
Su

Hi Anand,

We have five different sputter tools at UCSB. Two older SFI systems,
two AJA systems and a custom built Kurt J Lesker tool. The two multi
target systems from AJA, http://www.ajaint.com/systems.htm are our most
current purchases.  We have had great performance from the systems and
they will build to your requirements. The Lesker tool may be less
expensive than the AJA, but it has no bells and whistles and is a very
manual tool with a simple loadlock. It requires that you select and help
design the tool, but can save on cost. SFI was purchased by Tegal and at
this point I don't even know if they design new sputter tools.

Hope this helps,  Tom
