horizontally: contact litho works fine as long as you dont need <200um resolutions
<azonenberg>
Or if you're using commercially made film masks at 20um resolution (laserlab.com is a good vendor) and dont care about precise alignment relative to existing features

azonenberg: is this from experience?
<azonenberg>
Contact litho in real fab goes a lot smaller
<azonenberg>
But it requires more precise masks and usually you care about alignment
<azonenberg>
but on a cheap printer 200um resolution is easily doable with no optics using contact
<horizontally>
so why do you care about all this stuff being so small again?
<horizontally>
MEMS? why are you so interested in a comb drive?
<horizontally>
i don't quite even get how it works
<azonenberg>
It's the "hello world" of MEMS
<azonenberg>
as in a fairly simple device
<horizontally>
really hmm
<azonenberg>
same as a ring oscillator for CMOS (though i'd probably do a single transistor, then a single gate to start off)
<kristianpaul>
single transistor, thats a *must* :-)
<kristianpaul>
and then single LED :-D
<azonenberg>
LED is more tricky
<azonenberg>
that will need a III-IV semiconductor problaby
<azonenberg>
at least if i want it to emit in the visible range
<azonenberg>
IR i could probably do on silicon
<azonenberg>
i need to learn more about bandgaps etc
<kristianpaul>
sure, just kidding
<azonenberg>
And i'm serious :p
<kristianpaul>
:-)
<azonenberg>
i was thinking of making my own phototransistor too
<azonenberg>
that shouldnt be too tricky
<azonenberg>
large NPN device
<azonenberg>
with a huge exposed junction
<horizontally>
i wish my roommates were that motivated
<horizontally>
i got some dumbass psychology majors who don't know what they want to do in life
<azonenberg>
horizontally: i wish mine were :p
<azonenberg>
Ok
<horizontally>
Hokay
<azonenberg>
they're not that bad, they're all CS or CSYS majors
<azonenberg>
except for one who's an aeronautical engineer
<horizontally>
oh cool
<azonenberg>
and is, despite that, a competent coder :p
