But, SiGe transistors are still made. High-resistivity Ge deposition (probably chemical vapor deposition with germane) should work, even if the underlying wafer is not 'intrinsic' enough.
I thought Ge was less doping-sensitive than Si. How bad IS the (2014-era) Ge wafer supply, I wonder?
I have claw hammers with wooden handles and one-piece all steel hammers. My wife has a Tomboy Tools pink fiberglass-handle hammer. They're all about the size and shape, and work like, the one in the painting.
Beds and chairs and doors and stairs haven't changed much either, in
500 years. They work the same.The trend in computing devices, what with phones and tablets replacing big-box PCs, is towards *less* compute power. If we're stuck with 15 nm CMOS logic forever, we'll survive.

one of the youtube machinist have a serious hammer fetish :)

Good grief! 20 minutes of describing hammers?
Don't knock it.
I hear you knok'in, but you can't come in... something like that.
Stop. Hammer time!
Even if we were stuck with just today's technology forever it would get extremely cheap over time, and with gradual saturation implementation of computing and every known trick, resulting performance would still go up.

Reminds me of the IBM motto.

I'm sure there is people here with a similar fetish for some tool they stock pile in a, to outsiders, excessive number :)

If by that obscure reference you advert to my 9 oscilloscopes, I can assure you, Sir, that I can take them or leave them alone. ;)
Just got in an HP 70820A Microwave Transition Analyzer, which is a DC-40-GHz sampling scope/ spectrum analyzer / network analyzer / dynamic signal analyzer. They go for really cheap (this one was $775) because nobody knows what they are.

Ummm, I have about 60 oscilloscopes now. That's perfectly normal, isn't it?
You're right about that!

eI've got one, but I've yet to unpack it. Sixty would have been hard to fit into the biggest house we ever owned
Not entirely. I know enough about what it is to know that I need one about once per decade, and that it would make sense to hire it then, rather than tying up storage space for ten years between uses.
Yeah, but you have to share yours, whereas I get to Gollum, I mean Bogart, mine. ;)

The older stuff is collectables, not shared or much used any more.
535s, 545s, 547s, 5000 series, 7000 series, a few really old Teks, tons of plugins.I learned picosecond stuff with this flea-market Tek 1S2:
And some HPs, including an HP185 with plugins, the first really modern sampling scope.
I have a histororical, but really crappy, Lumitron sampling box, intended to be used with a separate oscilloscope. Avalanche transistor and single point-contact diode sampler, ugly as sin.
In my case, connector crimpers or quarter-inch hex screwdriver bits. Or maybe computers (doesn't everyone have a few PDP-11 and Multibus CPU boards, though?).
Surely, a few dozen soldering irons isn't 'excessive'!
is this turning into confessions of tool hoarders? ;)
-Lasse
You only have NINE? :(
I have a couple rack mount Intel Multibus cases, a pile of Multibus boards, and some VAX boards, in storage.
