  1. Re:isotopically purified silicon by pfdietz · · Score: 1 · on New Solution For Your Transistor BBQ

    To answer my own question: Isonics is selling 28Si epi wafers. They are not yet selling 28Si bulk wafers (too expensive, I bet.)

  2. Re:Isotropic structure from purer Isotopes by Goner · · Score: 1 · on Isotropic Silicon?

    Even deeper, here's where the register got their info: Isonics.com page on 28Si

    And yeah, it's all about those little quantizations of thermal vibration => phonons. As some other good posts have mentioned.

  3. Re:Color me Skeptical by Angelwrath · · Score: 1 · on Isotropic Silicon?

    The company in question, which is sampling epitaxy wafers to two "major" semiconductor manufacturers (according to the website) is Isonics, a company trading on the NASDAQ (Symbol ISON) and based in Colorado. All of their operations are based in the US, the USSR organization developed the technology, but that technology is now available through a US vendor.

    So yes, it's true that the technology exists. The Max Planck Society has verified that the technology does indeed increase thermal conductivity as well. The Max Planck article here.

    Beyond the fact that the technology works, Isonics seems to believe that it will scale... why would they be shipping wafers to large semiconductor vendors if they couldn't deliver?

    As for the proliferation risk, that is entirely likely. Isonics already offers isotopically pure Oxygen 18, Carbon 12 and 13, and several other pure elements. As I understand it, they're also working to offer isotopically pure Germanium, so they're clearly going for products relevant to semiconductor manufacturers.

  5. Re:isotope vs. isotropic by Louis_Wu · · Score: 2 · on Isotropic Silicon?
    Your definitions are correct, but the story (despite what the Slashdot headline says) is actually about the "isotopic" (no "r") variety.
    True, the article and the science concentrate on the isotopic (chemical) aspects of this new method, but those isotopic methods introduce isotRopic characteristics into the silicon.

    To quote the FAQ, "By removing the different sized atoms, the lattice crystal structure becomes more uniform ..." - isotRopic means 'the same throughout, uniform.' So making a silicon lattice structure more isotopically pure helped to make that structure more isotRopic.

    Semantics, semantics, some antics. :)
