| azonenberg | hi hideo | 02:35 |
|---|---|---|
| hideo | hi | 02:35 |
| azonenberg | My roommate is finally bringing the lathe up this weekend :D | 02:36 |
| azonenberg | with any luck in a few days we can get to work on the new spin coater | 02:36 |
| hideo | i think i added this channel to my list but fucking lost the old config file | 02:36 |
| hideo | nice | 02:36 |
| azonenberg | 0-4000 RPM, fully variable (brushless DC motor) | 02:37 |
| hideo | i'm gonna follow up on the site now | 02:37 |
| azonenberg | 2-inch vacuum chuckl | 02:37 |
| azonenberg | chuck* | 02:37 |
| azonenberg | and ethernet connection to a process control server on one of my workstations | 02:37 |
| azonenberg | dont bother, nothign new on the googlecode repo in months | 02:37 |
| hideo | aww | 02:37 |
| azonenberg | school got in the way, things were slow | 02:37 |
| hideo | ok, update me? | 02:37 |
| azonenberg | i'm ramping up again now that its summer, got lots of new equipment in the lab | 02:37 |
| azonenberg | my new roommate is into MEMS too | 02:38 |
| azonenberg | and is a mechanical engineer | 02:38 |
| azonenberg | so he's going to be helping me out with a lot of the tooling | 02:38 |
| azonenberg | on the todo for the summer are a nice spin coater and a 2-inch H-line contact mask aligner | 02:38 |
| azonenberg | plus, if we have time, DC sputtering | 02:38 |
| hideo | what feature size are you targeting again? | 02:40 |
| azonenberg | My current short-term goal is to get contact litho working at 12.5um features | 02:42 |
| hideo | and wafer size? | 02:42 |
| azonenberg | 2 inch | 02:42 |
| azonenberg | 8000DPI film masks from laserlab.com cost about $60 per 10x16 inch sheet (12x18 but there are margins) | 02:42 |
| azonenberg | that's enough for a full 2-inch mask set if you cut it up | 02:42 |
| azonenberg | i'm giving up on in-house mask fab for now, at $60 per mask its not really worth spending >$1k on tooling | 02:43 |
| hideo | yeah | 02:44 |
| hideo | so what about the projection system? | 02:44 |
| hideo | btw azonenberg, do you happen to know where to source teflon coated tubes? | 02:45 |
| azonenberg | projection is back burnered | 02:47 |
| azonenberg | the FOV was too small to work out | 02:47 |
| azonenberg | without massively bigger and more expensive optics | 02:47 |
| azonenberg | but on the other hand, it's possible to do contact with no optics at all | 02:48 |
| hideo | https://secure.wikimedia.org/wikipedia/en/wiki/Etching_(microfabrication) | 02:53 |
| azonenberg | hideo: what about it? | 03:22 |
| hideo | azonenberg: oh nothing, just thought it maybe useful if you didn't already look at it | 03:22 |
| azonenberg | Lol no, i've seen it and then some | 03:22 |
