Subject: [mems-talk] Problem with DC Sputter


Dear Members,

I have a problem with my DC sputter. We used to sputter Nickel but we have
strange problem now having plasma inside chamber but unable to sputter
nickel. I thought of target poisoning and I cleaned the target with
Nitricacid and then also I was not able to move forward. Can anyone suggest
me in this!
