| B0101 | hi, I've heard about chlorine etching for Silicon. Is that possible? | 13:25 |
|---|---|---|
| Sync_ | I heard about using chlorine being used in rie and such | 13:26 |
| B0101 | But I don't think chlorine in normal room conditions work to "attack" silicon, does it? | 13:31 |
| Sync_ | I don't really know but I doubt it works | 13:31 |
| B0101 | anyone knows what 'SSP' stands for in wafer specifications? | 16:16 |
| Sync_ | single side polished I guess | 16:22 |
| berndj | i wonder if B0101 can get hold of platinum electrodes? | 19:21 |
| berndj | salt water + electrolysis with inert electrodes = NaOH solution! | 19:22 |
| Sync_ | and if you electrolyze longer you can get chlorate | 20:34 |
| berndj | or at an extreme, buy table salt, melt it, and electrolyze it | 21:32 |
| berndj | i've managed to melt NaCl in a BBQ fire, haven't figured out how to then also electrolyze it while it's >801C | 21:33 |
| Sync_ | you can melt it in an induction heater | 21:35 |
| Sync_ | but it is much more efficient to just get chlorate directly | 21:35 |
| berndj | why do we want chlorate? | 21:36 |
| berndj | i thought we're going for NaOH to etch Si | 21:36 |
| berndj | or are we making explosives now :) | 21:37 |
| Sync_ | well getting naoh is fair enough | 21:38 |
| Sync_ | when you are not living in singapore | 21:38 |
| berndj | yeah, i think it's the singapore problem we're solving. i can just go to the hardware store and buy 5kg of NaOH if i want. granted, of unknown purity | 21:39 |
| Sync_ | the real solution to the singapore problem is moving out | 21:40 |
| azonenberg | Sync_: lol | 21:59 |
| azonenberg | agreed | 21:59 |
| Sync_ | well no shit | 21:59 |
| Sync_ | there is no other solution to it | 22:00 |
