<azonenberg> hi hideo
<hideo> hi
<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
<hideo> nice
<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
<hideo> aww
<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> yeah
<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

<azonenberg> 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
