From jwc at snf.stanford.edu Wed Apr 14 10:26:50 2010 From: jwc at snf.stanford.edu (James W. Conway) Date: Wed, 14 Apr 2010 09:26:50 -0800 Subject: Hummer V Sputterer Target In-Reply-To: References: Message-ID: <4BC5FADA.7000305@snf.stanford.edu> The cathode currently in the hummer is a Pd target. It is very old but will give good contrast in SEM images. The films can be removed with KI:I Au anodic etch. My current plan is to run all the old targets until they are absolutely useless before considering any replacements. I have stopped providing new Au targets for this tool due to minority of Users whom had used this system to coat eye ware and other non-SEM operations. Which metal would you prefer if I were to order a target? Note SNF does not have any funds for these items at this time. Targets are $600 to $3000 USD!
