According to Len Booth, it may be time to have the machine completely rebuilt -- which could cost $45k or more. I know that the saw has been enabled an average of once per day this year, by 38 different users, so I imagine that I'm not the only person inconvenienced by this long-term shutdown. I would like to get an idea of how many users have immediate dicing needs, and whether anyone has information on using local foundries.

They charge a fee (but I don't remember how much) and you need to wait a few days. The shop is in Ginzton 129. Talk to Chris Remen (Ginzton 130 or 132?) to find more. Hope this helps.

It seems that CIS is struggling to pay for the installation of the recently donated Intel equipment, and is not anxious to have the wafersaw rebuilt. Regarding the Ginzton crystal shop: it will not be a dicing alternative for long since Chris Remen is leaving in two weeks (with no replacement in sight). Only a few students are now qualified to use the wafersaw in Ginzton (Chris runs a special class, offered once per year) and currently this saw is also broken. Note that even with Chris here, this wafersaw had constant problems -- without him, who knows.

Message-ID: <3909E328.3FF5E2EA@snf.stanford.edu> Wafersaw users - I've found some burned wiring in the wafersaw controller, which may account for the intermittantly strange actions of the saw. I was able to buy some replacement parts today, and hope to test the saw for proper performance by the middle of next week. Expect to see additional info on this by Wednesday 5/3. Len
