asciilifeform: amberglint: for microscopy, difficulty is in decap ( can't afford to lose samples to botched decap ) and then delayer ( i expect will need at least 1 shot with stripped metal , after surface shot , to get useful output )
asciilifeform: amberglint: most recent movement on this front, is that i found microscopy shop where reasonable price, but self-service -- gotta decap & delayer the thing personally ☝︎
asciilifeform: he didn't conjure up the delay map, but asciilifeform neither knows how to do this without seven figures' worth of microscopy

mircea_popescu: the idea being that there's an absolute limit to optical microscopy due to quantum phenomena (hence the heisenberg reference, his original work as critiqued by bohr dealt exactly with this). however, these limits also depend on frequency, and from comparing measurements in different lights one can get some error correction.
asciilifeform: not so much optical microscopy in current-day reversing biz ( not so many people bringing 1980s dies.. )
a111: Logged on 2018-11-28 15:59 asciilifeform: and 1uM was just about the last process where optical microscopy yields anyffin
asciilifeform: and 1uM was just about the last process where optical microscopy yields anyffin ☟︎
mircea_popescu: i mean, since you have the pumping infrastructure, costs comparatively little to isolate one room and do w/e in there, microscopy.
asciilifeform: ( admittedly 'eat' is broad concept for asciilifeform , includes 'microscopy budget' )
mircea_popescu: recall ? "put your pdf reader in a bot" "where are your microscopy shots" etc.
mircea_popescu: some of the microscopy-est clits + clitoral hoods + labia arrangements i ever saw lived between the legs of med students.
asciilifeform: speaking, upstack, of microscopy, did we ever do the 'why not gamma inspection, like for steel beams' thread ?
mircea_popescu: all the microscopy only needed for first debug unit though, rite ?
asciilifeform: learning anything from dies is veeery expensive, see the microscopy thread.
asciilifeform: considering that microscopy costs ~= toyota, a circus like that could easily carry on, 'under the radar', for several years.
mircea_popescu: http://btcbase.org/log/2018-01-05#1765236 << no that was the different one, with the microscopy. ☝︎
mircea_popescu: i recall something with robotic microscopy
asciilifeform: nope, saving it for all-in-one microscopy go.
asciilifeform: meeeaanwhile in failed experiments, asciilifeform tried to take an xray of the bolix-ivory die, so as to get moar realistic microscopy quote at some point. method : ra-226 capsule (commercial geiger test src), b&w 'polaroid' film. weakness turns out to be the latter : when developed using rolling pin, fixer pouch bursts, and result is liquishit
asciilifeform: ( in further continuation of the microscopy q : what the everliving fuck happened to the beta ray microscope ? theoretically can do ~same thing as sem, but no need for massive electron gun, million volt power supply, or the vacuum pumps. where is it ?? )
asciilifeform: before i fughet, here's asciilifeform's microscopy crackpottery of the day : contact print. consider, 370,000 transistors, on item roughly 1cm x 1cm. attach to standard ccd, say the 25 megapixel sort, and image with e.g. soft xray.
a111: Logged on 2017-11-14 14:55 asciilifeform: in sadder noose, cheapest bolix ivory microscopy quote, chinese, that covers all the layers ( metal and passivation ) is ~30,000 usd.

asciilifeform: if yer thing is multilayered you'd ideally have the microscopy done in same house.
mircea_popescu: (likbez : the result of microscopy is a set, of levels, that are not numbers in the proper sense. consequently you wish to see a list of them, but can not do implicit color conversions such as blue+yellow = green, because color #45 the microscope saw has nothing to do with #65 or #72)
mircea_popescu: this way you actually have a de facto lossless, and rather useful, microscopy remote format.
kanzure: microscopy is supposed to be gifs? next you're going to tell me webm
mircea_popescu: kanzure the overhead of movement is 90% + of the cost you incur ; and 1% or less of the point of interest. microscopy is supposed to be gifs. and correctly colorized so as to allow me to get back the electron microscope original.
mircea_popescu: < kanzure> also it's because i feel ashamed for not having thousands of hours of microscopy video already << i hope shame intensifies. but in any case : why the fuck wouldf you make it video.
asciilifeform: my microscopy plans are very modest : 1uM ic dies.
a111: Logged on 2017-08-22 14:35 asciilifeform: when saw that the ~original~ src was a pile of shithacks, lost interest in anything but the electron microscopy path ( like it or not, 1uM process folks were ~forced~ to make compact description )

asciilifeform: mircea_popescu: 100% of what can be reversed without electron microscopy, is already public
asciilifeform: overall i suspect this is a more productive attack than microscopy ( though the thing was fabbed at 1 uM, it would be quite visible on optical microscope )
asciilifeform: there were not so many tech leaps comparable to hard vacuum (which makes possible everything from triode -- ergo, tuned radio, cathode tube, geiger, electron microscopy, 1,000,001 everyday items )
asciilifeform: in other lulz, https://www.chipworks.com/about-chipworks/overview/blog/scanning-microwave-impedance-microscopy-smim << this looks quite buildable, using same mechanical rigging as the classic 'STM in your kitchen' recipe
mircea_popescu: i thought metal is extremely visible in electron microscopy
asciilifeform: at one point i considered buying one, but was not able to swing the access to the needed microscopy
asciilifeform: i've always wanted to do a bit of microscopy on those, see if there was a set of magicks for re-enabling the 'accidented' cores
