more than 1000 transistors on it...

Only claims 100 on a chip,

quote
Then his homemade photolithography machine beamed on his design: a grid of 12 circuits,
each with 100 transistors (and a dancing bear), 1,200 transistors in all.
end quote

so 100 per circuit, 12 circuits on a \'wafer\' ?


but the metallization doesn\'t connect to that many; I\'m not sure how complex
the circuitry can be, but it looks like a rather simpler circuit, like a differential pair and some
current mirrors. It could hold an op amp, that uses external bias resistors (don\'t see
any sign of FET or CMOS or both NPN and PNP transistor types).

His basic idea, it seems, is that small-scale production is possible and instructive.
Imagine a six-man shop that can produce integrated devices with quick turnaround.
Would that be a useful addition to a maze of megacorporations with ever-changing
off-the-shelf designs, big plants, and long turnaround, but cryptic spec sheets
and big foundry toolchain complexities (and surcharges)?

For prototypes, heck yes. Bill Sloman can sell \'em some e-beam litho tools.

He is now 22, wait a few more years what else he comes up with.
And then China gets into it
Maybe your own chip-making machine on ebay for $999.99 .....
:)
Very impressive !

At 22 years old, how does he pay for all that nice stuff he\'s got ?
The HP gear and microscope, etc ?

Somehow I don\'t think he has to have a day job unless he just does
this in his spare time.

A rich parent who is with it will be far happier seeing his money go into scopes and electronics vs drugs and rehab. A stint in
rehab for kids of wealthy parents will cost more than his lab setup

At 22 I was working and accumulating all sort of electronics at home... rented bedsit in other city than my parents.
Build a TV and designed and build a vidicon TV camera... 1968
That landed me a job at the national TV network the next year, and more electronics accumulated at home.
Addiction to electronics perhaps.
Nothing much changed to this day :)

Very cool! In California, he would likely be jailed for having \"gasp!\"
chemicals in his garage! Certainly must be making bombs...

Yes this is a common problem with society these days, even kitchen knives are forbidden?
It will all change after the next nu-culear war and making sausages on the hot plutonium.

It\'s even more of a CA problem. My favorite is how it\'s illegal to use 100
or even 99% isopropyl alcohol there. You\'re seriously supposed to cut it
to 80% (or something like that) or less with water or acetone. They
actually fine companies for selling high grade isopropyl alcohol there
too. Clearly all other problems been solved.

Sounds bizarre. Analytical grade isopropyl alcohol has to be 99% pure (or better), and chemical supply companies have to be able to ship it to chemical laboratories or fine chemical manufacturing plants. What you local pharmacist can sell over the counter may be more restricted.

Are you sure that you know what you are talking about?

How can he connect it? Did he get a wire bond machine from ebay too?

The wire bond machines have always been the part of the process that I
find most impressive, because they combine precision with fast moving
parts.

Yeah, I do.

top matchs are all fines or settlements for selling standard products for
industry in the shithole known as CA

parts.

You mean like pick and place machines? They may not have quite as much accuracy, but they are certainly in the same ball park. I see mentions of 0.001\" or 25 um. How accurate are wire bonding machines? I see one mention of 2.5 um. So maybe 10x?

Pick and Place has to maintain these numbers over distances ranging towards a meter. Wire bonding only needs to operate over a range of a cm or so. I know wire bonding is very fast, but for pick and place the long distance and the weight of the object being placed is much more in some cases. Handling a wide range of sizes is not easy either. I wonder just how long they maintain these specs as they wear?

I find it interesting to watch a pick and place operate. One I saw had multiple heads so multiple pieces could be picked up with less movement while being placed.

A manually operated wire bonder doesn\'t look any different from a fancy
optical microscope. I was recently told quite a bit of this work is still
done by hand. The one I saw had no wire instaled, so I didn\'t get to play
with it for real.
