I use one of these, but not for semiconductors. I doesn't sputter, it deposits 
thin films by thermal evaporation, but in a more controlled fashion than simple 
filament evaporation. My "Knudsen Cell" is a special custom built (by me) 
version used primarily for high refractive index coatings.

Back when I was still doing CF experiments I used it to deposit palladium on 
both Raney nickel and activated charcoal. So doing I got much better and more 
definitive results than Mr. Arata. I imagine this is because the palladium had 
never been exposed to air or water vapor before the introduction of deuterium.
