[labnetwork] Ti Sputtering with a Lesker Torus MagKeeper without a backing plate

[Carsen Kline]

Hi Tucson,

Except for extremely hard (W, Mo) or brittle materials (pressed powder oxides or nitrides), our MagKeeper targets are directly drilled and tapped with a single hole to attach the keeper button, no backing plate needed. Our target vendor provides this service and will also retrofit non-keeper targets in their machine shop.

I would not attempt to run a non-keeper target on a MagKeeper gun, especially if it's inclined at an angle.

Cheers,

Carsen

Subject: [labnetwork] Ti Sputtering with a Lesker Torus MagKeeper without a backing plate


Hello all,



I have a Lesker PRO-Line Sputter tool and the guns have Torus MagKeepers. I have a student that would like to sputter Ti. I have a Ti target, but it doesn’t have a backing. All of my other targets have backings. It seems logical that if I want to use a target on a gun with a MagKeeper I would need a backing (pictured is my Al target with a backing).



I asked our Lesker sales rep and his response was to use the Ti target without the backing. I asked if the target will slide off of the gun. His response was no.



Does this make sense? Does anyone have experience with sputtering Ti in a Lesker tool?
