<B0101> azonenberg: you there?
<azonenberg> Yep
<azonenberg> Been AFK for a while, end of semester craziness
<azonenberg> But i'm drawing up designs for a contact mask aligner i want to build over the winter
<B0101> ok, sorry for being off for long time though. Restarting experiments soon
<azonenberg> No worries
<azonenberg> Me too lol
<azonenberg> Anybody seen swkhan lately btw?
<B0101> nope...
<horizontally> hey azonenberg how do you deal with the photoresist in terms of safety? gloves? respirator? how suspectible is it really to ambient light cross-linking the polymer when you don't want it to?
<azonenberg> horizontally: First off, it's positive resist
<azonenberg> It starts out crosslinked and UV weakens it
<azonenberg> You're thinking of negative
<horizontally> yeah i have negative
<azonenberg> which also exists, but is not the type I use
<horizontally> why does positive give you finer resolution?
<horizontally> i read a lot about polymers
<azonenberg> Its what i could get hold of easier, actually :p
<azonenberg> In terms of safety, i wear goggles, gloves, and a lab coat as per SOP whenever working with anything more toxic than water
<azonenberg> the fumes are nasty but if i am only doing one die i just leave a window open and try not to lean over it when coating
<azonenberg> In the longer term i am building a local exhaust system
<horizontally> azonenberg: er, well it's been documented that the trend for the semiconductor industry was to go from negative to positive
<horizontally> oh right
<azonenberg> Which is one of the several things keeping me away from actual experimental fab at the moment lol
<horizontally> man i could stand to learn a lot from you
<horizontally> and you could stand to waste a lot of time on me
<azonenberg> Lol, waste time? I'm using it well
<azonenberg> Doing things like IRCing when i should be working on the NSF proposal my advisor needs me to get done last week
<azonenberg> Or the homework i have due in ten hours
<horizontally> oh shit
<azonenberg> :p
<horizontally> oh damn
<horizontally> all right i'll stfu
<azonenberg> Lol, keep talking and i'll answer eventually
<azonenberg> Just wanted to let you know i'm a bit busy atm :p
<B0101> azonenberg: I gtg. ttyl.
