hi hideo
<
azonenberg>
My roommate is finally bringing the lathe up this weekend :D
<
azonenberg>
with any luck in a few days we can get to work on the new spin coater
<
hideo>
i think i added this channel to my list but fucking lost the old config file
<
azonenberg>
0-4000 RPM, fully variable (brushless DC motor)
<
hideo>
i'm gonna follow up on the site now
<
azonenberg>
2-inch vacuum chuckl
<
azonenberg>
chuck*
<
azonenberg>
and ethernet connection to a process control server on one of my workstations
<
azonenberg>
dont bother, nothign new on the googlecode repo in months
<
azonenberg>
school got in the way, things were slow
<
hideo>
ok, update me?
<
azonenberg>
i'm ramping up again now that its summer, got lots of new equipment in the lab
<
azonenberg>
my new roommate is into MEMS too
<
azonenberg>
and is a mechanical engineer
<
azonenberg>
so he's going to be helping me out with a lot of the tooling
<
azonenberg>
on the todo for the summer are a nice spin coater and a 2-inch H-line contact mask aligner
<
azonenberg>
plus, if we have time, DC sputtering
<
hideo>
what feature size are you targeting again?
<
azonenberg>
My current short-term goal is to get contact litho working at 12.5um features
<
hideo>
and wafer size?
<
azonenberg>
2 inch
<
azonenberg>
8000DPI film masks from laserlab.com cost about $60 per 10x16 inch sheet (12x18 but there are margins)
<
azonenberg>
that's enough for a full 2-inch mask set if you cut it up
<
azonenberg>
i'm giving up on in-house mask fab for now, at $60 per mask its not really worth spending >$1k on tooling
<
hideo>
so what about the projection system?
<
hideo>
btw azonenberg, do you happen to know where to source teflon coated tubes?
<
azonenberg>
projection is back burnered
<
azonenberg>
the FOV was too small to work out
<
azonenberg>
without massively bigger and more expensive optics
<
azonenberg>
but on the other hand, it's possible to do contact with no optics at all

hideo: what about it?
<
hideo>
azonenberg: oh nothing, just thought it maybe useful if you didn't already look at it
<
azonenberg>
Lol no, i've seen it and then some
