| B0101 | azonenberg: you there? | 07:00 |
|---|---|---|
| azonenberg | Yep | 07:01 |
| azonenberg | Been AFK for a while, end of semester craziness | 07:01 |
| azonenberg | But i'm drawing up designs for a contact mask aligner i want to build over the winter | 07:01 |
| B0101 | ok, sorry for being off for long time though. Restarting experiments soon | 07:04 |
| azonenberg | No worries | 07:06 |
| azonenberg | Me too lol | 07:06 |
| azonenberg | Anybody seen swkhan lately btw? | 07:06 |
| B0101 | nope... | 07:06 |
| 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? | 07:10 |
| azonenberg | horizontally: First off, it's positive resist | 07:10 |
| azonenberg | It starts out crosslinked and UV weakens it | 07:11 |
| azonenberg | You're thinking of negative | 07:11 |
| horizontally | yeah i have negative | 07:11 |
| azonenberg | which also exists, but is not the type I use | 07:11 |
| horizontally | why does positive give you finer resolution? | 07:11 |
| horizontally | i read a lot about polymers | 07:11 |
| azonenberg | Its what i could get hold of easier, actually :p | 07:11 |
| azonenberg | In terms of safety, i wear goggles, gloves, and a lab coat as per SOP whenever working with anything more toxic than water | 07:11 |
| 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 | 07:11 |
| azonenberg | In the longer term i am building a local exhaust system | 07:12 |
| horizontally | azonenberg: er, well it's been documented that the trend for the semiconductor industry was to go from negative to positive | 07:12 |
| horizontally | oh right | 07:12 |
| azonenberg | Which is one of the several things keeping me away from actual experimental fab at the moment lol | 07:12 |
| horizontally | man i could stand to learn a lot from you | 07:12 |
| horizontally | and you could stand to waste a lot of time on me | 07:12 |
| azonenberg | Lol, waste time? I'm using it well | 07:12 |
| azonenberg | Doing things like IRCing when i should be working on the NSF proposal my advisor needs me to get done last week | 07:13 |
| azonenberg | Or the homework i have due in ten hours | 07:13 |
| horizontally | oh shit | 07:13 |
| azonenberg | :p | 07:13 |
| horizontally | oh damn | 07:13 |
| horizontally | all right i'll stfu | 07:13 |
| azonenberg | Lol, keep talking and i'll answer eventually | 07:17 |
| azonenberg | Just wanted to let you know i'm a bit busy atm :p | 07:17 |
| B0101 | azonenberg: I gtg. ttyl. | 07:18 |
