In a second part of the experiment, the researchers tested the ability of the laser to selectively remove hydrogen from the surface of the silicon when other types of atoms were present, in an effort to broaden the implication of their findings. When they included deuterium atoms (a heavy form of hydrogen) on the silicon, the laser stripped away only the hydrogen, leaving the deuterium behind. (Since the deuterium atoms are heavier, they don't vibrate at the same frequency as hydrogen and are therefore invisible to the 4.8 micrometer wavelength light, Tolk explains.)
One of the next steps for the researchers, says Leonard Feldman, physics professor at Vanderbilt and a researcher on the team, is to test their bond-breaking technique on the type of silicon that has a crystal structure most commonly used in the semiconductor industry. (In the experiment, the researchers used silicon with a crystal structure that had been studied thoroughly in terms of silicon-hydrogen bond formation and breaking.) Also, he says, in order to get a broader understanding of the physical processes involved in breaking hydrogen bonds, the researchers will test materials other than silicon, such as diamond, which "tends to behave like silicon" in terms of hydrogen bonding, Tolk says.

When to heat the wafer to 800 degrees Celsiius?
Could the author share the idea about when to heat the wafer to 800 degree in standard CMOS process flow? If you are talking about oxidation, you need high temperature anyway. For thermal annealing, this approach does not serve the purpose. Other than those steps, when do we need such high temperature?

I am a little skeptical of the purpose of this new technology. New technology is supposed to fix a problem, however, this just creates another that sounds like a pain to fix. I would like to know more about this this laser techique and how it can impact other silicon products.
laser technique seems to be pretty crucial, but who knows if this guy is for real. The things he says seems to make sense, but why is he talking about this stuff if he is not finished making the right laser. first of all, a laser that removes hydrogen bonds would probably be pretty expensive. Also, i don't even believe that this jackass will be able to remove the hydrogen as long as other atoms on the hygroden. This guy is a joke and he acts like he is so smart but he should keep his mouth shut until he solves the problem and can use this "laser" to make chiops faster

new life for old silicone
we always hear that silicone's days of usefullness are ending--and yet, here is a marvelous new way to continue our long association even farther. congrats to the reasearchers.

Silicone?
Did u know.. silicone is the stuff used in breast implants? while silicon is used in microprocessors, ICs, etc.

Silicon & Silicone
Silicon and Silicone are two different things. Silicon is a kind of crystal with a symbol of Si. Silicone is a semi-organic polymers with a symbol of R2SiO.
