asciilifeform: ^ ion beam epitaxy, for instance, is this

asciilifeform: !#s ion beam
asciilifeform: ftr, if the amd turd is anything like other recent similar, you will also need ion beam machine

asciilifeform: circuitry with the ion beam ... I realized what was going on almost instantly: the antenna effect. The bond wire and leadframe connected to each pad in the device was acting as an antenna and coupling some of the 13.56 MHz RF energy from the plasma into the input buffers, blowing out the ESD diodes and input transistors, and leaving me with a dead chip.'
asciilifeform: http://log.bitcoin-assets.com/?date=30-10-2015#1311697 << almost forgot to point out: this generally won't read a modern rom, certainly not a 16nm one that was built by folks who didn't want it read. you need an ion beam machine and much sweat, to strip away the layers. ☝︎
asciilifeform: i can, barely, afford, e.g., electron microscope. or the parts to build an ion beam machine. but what i cannot even remotely afford is the -time-.
asciilifeform: that'd be the extant 'ion beam workstation'
asciilifeform: the equivalent of a 'printer' for ic would be something like an ion beam gun station
asciilifeform should like the answer to 'how do i grow single-crystal si in jungle conditions, how do i lay down dopant with ion beam sans high vacuum' etc.
asciilifeform: mircea_popescu: give man a few days with ion beam workstation.
asciilifeform: but the real treasure - unlimited free time - makes ion beam workstation look like a 'dollar store' souvenir.
asciilifeform: BingoBoingo: some aspire to, e.g., electron microscope, or six-axis vertical mill, or ion beam workstation.
asciilifeform: not possible to release HW-1 with an open firmware due to NDA << anybody got an ion beam machine? 'gentlemen, start your engines.'
asciilifeform: (electron microscope, ion beam machine, etc.)
asciilifeform: BingoBoingo: microscope alone isn't of terribly much use for reversing. also would need ion beam machine, for stripping layers, etc.
mircea_popescu: you have any idea how slow ion/beam engines move ?
benkay: asciilifeform a friend of mine built an ion beam microscope
asciilifeform: ion beam (http://en.wikipedia.org/wiki/Ion_beam_deposition) is ever so slightly more doable, I suspect.
asciilifeform: I'm more interested in the ion beam deposition approach, rather than optical masks, though
