[3dem] Carbon evaporator for SPA

[Jasnin, Marion]

Hi Marion,


Thanks a lot for the brochure and your input. We also like the safematic a lot.


Cheers,

Marion

Hello marion,
we have the safematic at the institute, very easy to use with turbo dry pump and quartz crystal for thickness measurement. We use it routinely for 2nm carbon by evaporation on mica to make a continuous film on the grids for the SPA and are very satisfied. Also Safematic's circular chamber system is esay to clean and it has an automatic carbon wick unwinding really convenient and reproducible.

I'll leave you a small attachment on this machine.

best

marion

Dear all,

we are in the process of buying a carbon evaporator for producing additional 5-15nm support films in SPA. Our experience in making carbon films is based on older machines that are no longer available. So far, we got two quotes more on the high-end side of the instrument spectrum but considering the good quality films we were able to produce with the old machines we are wondering if such an investment is necessary for SPA:

Leica EM ACE600 Carbon Thread Coater
* Carbon thread evaporation
* Oil free UHV pump system with turbomolecular pump
* Quartz crystal thickness measurement
* Sample stage rotation

Quorum Q150V E Plus
* Carbon rod evaporation
* Oil free UHV pump system with turbomolecular pump
* Quartz crystal thickness measurement
* Sample stage rotation

Much cheaper options like the Leica EM ACE200 exist. We would appreciate some advice on how important expensive features like ultra high vacuum or sample stage rotation really are for SPA.  Hints which instrument you are successfully using for this application would also be very helpful.

Thank you,
Cheers,
Marion
