azonenberg_lab: hey just a heads up I showed your "Intel 4004 replica" project to 2 guys from Intel Labs yesterday
<wolfspraul>
I told them they should find someone inside Intel to support it :-) (nothing will come out of this I'm sure, but they liked it and took lots of notes...)
<azonenberg_lab>
wolfspraul: Lol, nice
<Harold_parker>
fuckk azonenberg that is beautiful!!!!!!
<azonenberg_lab>
Harold_parker: ty :)
<Harold_parker>
fuckin eh man :D
<Harold_parker>
how many runs did it take to get that beauty?
<azonenberg_lab>
A couple, maybe ten
<azonenberg_lab>
All were <5um
<azonenberg_lab>
this is the sharpest i've gotten yet
<Harold_parker>
niiice!
<azonenberg_lab>
The next step is a digitally controlled power supply
<azonenberg_lab>
to automatically cut off power right when it detects the maximum sharpness right after the end breaks off
<Harold_parker>
hmmm, not quite sure i follow?
<Harold_parker>
in case of an accident?
<azonenberg_lab>
No
<azonenberg_lab>
The etching is fastest right at the surface
<Harold_parker>
ahhhhhhhhhh
<Harold_parker>
rght
<azonenberg_lab>
and there's a thicker part below that
<Harold_parker>
got it
<azonenberg_lab>
So right when it snaps you're at max sharpness
<azonenberg_lab>
But if you etch any further it dulls
<Harold_parker>
got it
<Harold_parker>
and then it blunts
<Harold_parker>
right
<Harold_parker>
nice :)
<azonenberg_lab>
I've seen papers that did cutoff in 500ns
<Harold_parker>
man awesome
<azonenberg_lab>
and hit 3.5nm points
<Harold_parker>
hahahahaha
<Harold_parker>
:D
<Harold_parker>
omfg
<Harold_parker>
thats awesome
<azonenberg_lab>
I dont want that sharp lol
<azonenberg_lab>
I want maybe 200nm
<Harold_parker>
lol indeed
<Harold_parker>
yeh
<azonenberg_lab>
But i also want to be able to dial in "give me a point of this size"
<azonenberg_lab>
and it'll calculate how long to post-etch to do that
<Harold_parker>
oooooh
<Harold_parker>
nice!
<Harold_parker>
thats a sweet idea there man
<Harold_parker>
very very sweet!
<berndj>
that pic looks almost like some X-15 zipping through the stratosphere
<azonenberg_lab>
berndj: You're not the first to make that comment
<azonenberg_lab>
But its just a little small ;)
<berndj>
does it matter if your probe is "wobbly"? i don't expect that sort of aspect ratio to give you a very stiff probe
<azonenberg_lab>
berndj: Aspect ratio is somewhat variably by controlling etch rate
<azonenberg_lab>
And usually it doesnt matter
<azonenberg_lab>
You dont push down too hard
<ziper>
yo
<azonenberg_lab>
hi ziper
<azonenberg_lab>
berndj: You just gently push it down until it makes contact
<azonenberg_lab>
If you have coarse micropositioners like i do (designed for hitting bond pads, test points, and other >=5um targets) its a little tricky lol
<azonenberg_lab>
Go down just a hair too far and the point bends :p
<azonenberg_lab>
Which is why i want to make duller points for those things
<azonenberg_lab>
The only reason i'd use such a sharp one is for an STM or similar non-contact application
<azonenberg_lab>
So... let's see, its 23:20 here
<azonenberg_lab>
But i have a couple more experiments to run before bedtime lol
<ziper>
azonenberg_lab, what are practical applications of this?
<azonenberg_lab>
Gonna have to pick up some of this my next order (i need more swabs and lint-free wipes some time too)
<azonenberg_lab>
No mention of any added denatonium benzoate or similar
<bart416>
while you're at it, pick up some ClF3 to put in small little aluminium containers and then hide it in people's pockets?
<azonenberg_lab>
bart416: um, no thanks
<azonenberg_lab>
a) they dont sell it
<azonenberg_lab>
b) i dont want to get anywhere near it
<bart416>
c) does anybody actually know how to extinguish a fire with that stuff?
<bart416>
d) not really no
<bart416>
e) all lab safety manuals tell you to run away if something goes wrong with that
<azonenberg_lab>
Lol, pretty much
<azonenberg_lab>
and hmm, radioshack msds doesnt list the bitterant either
<azonenberg_lab>
grr... why cant they include mass spec data or something as well as the hazardous ingredients list? :P
<azonenberg_lab>
I want to know if there's something in there at 500 ppm that can mess up my project lol
<azonenberg_lab>
But that is something worth trying
<bart416>
THey're not required to mention it cause the percentage is too low :P
<azonenberg_lab>
squirt a lot of this on something and compare its properties to something not so squirted
<azonenberg_lab>
see if any residue is visible
<bart416>
Don't you have a mass spectrometer over there? :P
<azonenberg_lab>
if its just an odorant like they add to gas its fine
<azonenberg_lab>
bart416: At home? No
<azonenberg_lab>
On campus? I'd expect several
<azonenberg_lab>
but i dont know who runs them or how to use them
<bart416>
I'm going to guess the chemistry and physics department
<bart416>
Maybe electronics has one as well
<azonenberg_lab>
I meant which faculty / labs
<azonenberg_lab>
also, i dont think its the problem, i blew it on a glass slide and saw no residue
<bart416>
Dunno, here chemical engineering had several
<azonenberg_lab>
now starting to suspect the stuff i saw on the thing was actually depositing from contaimination in the rinse bath
<azonenberg_lab>
that i was drying it from
<bart416>
Why did I spend so much time last year helping that asshat of a girl use one of those things for a stupid report she was writing >_>
<bart416>
Should have sabotaged it
<azonenberg_lab>
Lol
<azonenberg_lab>
Was she being nasty then too?
<R0b0t1>
Because she has breasts, bart416.
<azonenberg_lab>
Or being extra nice so you'd help
<azonenberg_lab>
knows a female bio major who owes him a big favor after a similar situation
<azonenberg_lab>
.docx format file got hosed the day before the paper was due
<azonenberg_lab>
and of course i was the one she came to to fix it
<azonenberg_lab>
Though i had a bit of an ulterior motive, i will freely admit
<azonenberg_lab>
i was hoping she could get me time on one of the confocal fluorescence microscopes
<azonenberg_lab>
Well, off to sleep for me - experiments today were largely successful but that doesnt mean i have any less work to do at my day job tmrw :P
<CIA-67>
homecmos r95 | trunk/lithography-tests/labnotes/azonenberg_labnotes.txt | Updated lab notes for remainder of today's experiments.
<bart416>
<azonenberg_lab> Or being extra nice so you'd help <-- that
<azonenberg_lab>
bart416: lol
<azonenberg_lab>
Its a survival skill any girl at an engineering school will learn
<bart416>
Though for me it was cause I actually liked her, not to get time on microscopes >_>
<azonenberg_lab>
Especially a good-looking one with below average talent
<bart416>
The thing is, she's really smart
<bart416>
Way smarter than me
<azonenberg_lab>
And in my case, she was smart and somewhat crazy
<bart416>
But she still asked for my help :S
<azonenberg_lab>
And not my type
<azonenberg_lab>
She tried to convince me to go to a *party*
<bart416>
I tried to convince her to go to places but she never wanted to :(
<azonenberg_lab>
If it was somebody i liked i'd invite her over the lab :P
<azonenberg_lab>
Somebody who appreciates that i could get along with
<bart416>
And the one time I did convince her a stupid friend of hers ruins it for me
<azonenberg_lab>
i see lol
<bart416>
But I doubt she ever actually liked me if I look at it afterwards
<azonenberg_lab>
Yeah, even at engineering schools there arent many people (of either gender) who are even close to my level of geekiness
<bart416>
But yeah, sort of hurts :(
<bart416>
I blend in fairly well :p
<bart416>
acts stupid most of the time
<bart416>
On IRC as well >_>
<azonenberg_lab>
If you add a "AND `gender`='f' AND `relstatus` = 'single'" to the query...
<azonenberg_lab>
the result set shrinks even further :p
<bart416>
?
<azonenberg_lab>
sql query lol
<bart416>
what's the first part of the query :P
<azonenberg_lab>
SELECT * FROM people WHERE geekiness > kGeeky*my_geekiness AND distance(location, my_location) < kDist
<azonenberg_lab>
lol
<azonenberg_lab>
But there are a few out there
<azonenberg_lab>
I hear the bio department has a few female H. Sapiens in captivity being studied :P
<bart416>
lol
<azonenberg_lab>
In all seriousness, a few can be found
<bart416>
Here as well
<azonenberg_lab>
my "not-gf" (close female friend but we arent dating) is one, last time we were hanging out the conversation turned to gravitational fields around spinning black holes pretty quickly lol
<bart416>
I'll admit I wouldn't hang out with you in real life :|
<azonenberg_lab>
Lol, thats probably true of most people here
<azonenberg_lab>
even the CIA bot ;)
<bart416>
If I go to a bar with some friends I like to talk about not so serious stuff
<azonenberg_lab>
And thats one of the things that annoys me about normal people sometimes lol
<bart416>
And if it goes scientific it usually involves excessive amounts of explosives
<azonenberg_lab>
I live the stuff
<bart416>
You have a general geek issue
<azonenberg_lab>
When i'm not doing my day job or consulting for a nanotech startup
<bart416>
I only have the math issue
<azonenberg_lab>
I'm doing chip fab
<azonenberg_lab>
Or coding, or CPU design
<azonenberg_lab>
Or reading papers that I think might be useful for my thesis work
<bart416>
You can do that
<azonenberg_lab>
lol
<azonenberg_lab>
I think my brain is somewhat like a high speed electric motor
<azonenberg_lab>
It needs to be under load all the time
<azonenberg_lab>
or bad things happen
<azonenberg_lab>
In the motor's case, it burns out the bearings
<bart416>
But in my case it usually goes like this: Get up, go for a run, breakfast, shower, study a bit or do something useful, play some computer game, lunch, do something (hopefully involving female attention), dinner, study/work a bit, watch some films or series, sleep
<azonenberg_lab>
In my case, i invent a load P
<bart416>
The only thing that so far managed to block math out of my head is sitting next to a person I like :|
<azonenberg_lab>
Even that wont do it for me lol
<azonenberg_lab>
We end up talking math :P
<azonenberg_lab>
Though not exclusively
<bart416>
Heh
<bart416>
My math problem is of the nature, give me anything and my head will solve it without me realising it
<azonenberg_lab>
And my schedule...
<bart416>
But in doing so it seems to take resources away from other things
<bart416>
Bad bad resource manager!
<bart416>
Don't make me ctrl alt escape you!
<azonenberg_lab>
Get up, quick breakfast+shower, walk a mile-ish up to campus, classes and research, lunch if i'm not too absorbed in my work to realize i'm hungry, homework if any, research/consulting work, quick dinner (often while reading papers or something, sometimes skipped in favor of a granola bar or something if i'm glued to my work), sleep whenever i realize what time it is
<bart416>
That doesn't sound all too healthy
<azonenberg_lab>
I have a tendency to lose track of time and miss dinner or stay up way past when i should because i didnt notice how long i've been working :P
<azonenberg_lab>
bart416: And i've tried the "relaxing" thing
<azonenberg_lab>
Just doesnt work for me
<azonenberg_lab>
after i got my bachelor's degree i went down the shore with the family for a week
<azonenberg_lab>
Ended up spending most of the afternoons designing masks and processes for this project
<azonenberg_lab>
because my mind couldn't stand being idle
<bart416>
That's what you get female friends for o_O
<bart416>
They'll drag you along and force you to have fun anyway
<azonenberg_lab>
bart416: Depends on the type
<bart416>
ok, the type I like :P
<azonenberg_lab>
The one i was talking about is a rabid MMO player :P
<bart416>
Know some of those but they're usually fat and ugly
<azonenberg_lab>
She's a bit above average but far from fat and distinctly cute lol
<azonenberg_lab>
Was quite suprised to hear she was a diehard RPGer
<azonenberg_lab>
Then again, first glance at me IRL would probably not give the impression of a guy with a chip foundry in his living room
<azonenberg_lab>
especially if i happen to be talking about some other equally technical but unrelated subject
<azonenberg_lab>
Oh, and the other geeky female friend i have? EE masters student doing her thesis work on sputtering
<bart416>
heh
<azonenberg_lab>
and if i can convince her to tear herself away from the fancy RF sputtering rig in her lab for a little while and help debug mine...
<azonenberg_lab>
Maybe i can get working metal deposition by next year
<bart416>
lol
<azonenberg_lab>
though first things first, i need an argon tank and a roughing pump
<azonenberg_lab>
And before that, probably some sleep :P
