hi, I've heard about chlorine etching for Silicon. Is that possible?
<Sync_>
I heard about using chlorine being used in rie and such
<B0101>
But I don't think chlorine in normal room conditions work to "attack" silicon, does it?
<Sync_>
I don't really know but I doubt it works

anyone knows what 'SSP' stands for in wafer specifications?

single side polished I guess

i wonder if B0101 can get hold of platinum electrodes?
<berndj>
salt water + electrolysis with inert electrodes = NaOH solution!
<Sync_>
and if you electrolyze longer you can get chlorate

<berndj>
or at an extreme, buy table salt, melt it, and electrolyze it
<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
<Sync_>
you can melt it in an induction heater
<Sync_>
but it is much more efficient to just get chlorate directly
<berndj>
why do we want chlorate?
<berndj>
i thought we're going for NaOH to etch Si
<berndj>
or are we making explosives now :)
<Sync_>
well getting naoh is fair enough
<Sync_>
when you are not living in singapore
<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
<Sync_>
the real solution to the singapore problem is moving out
