Reduce Transistor Power Consumption
revelCyllufyalP writes to tell us that University of Kentucky researchers have discovered a way to reduce the overall power consumption of transistors. From the article: "In order to improve computer chips' performance, transistors' size and gate insulators have to be continuously shrunken so that more components can be packed into a single chip. Computer chip producers were hitting a wall in downscaling the transistors and gate insulators because of their inability to reduce the leakage current of the existing gate insulators. This new technique will help the chip producers to develop more powerful chips with low-power consumption."
As probably one of the few semiconductor geeks on /., I have to say: Where's the news? Gate dielectrics are always made with rapid thermal processing on current technologies. Basically, stick a wafer in a chamber, flow some gas, turn on some super-high intensity
lamps, heat the wafer to >1000C for a very brief time, grow a few atomic layers of silicon dioxide (or some variant that includes nitrogen), turn off lamps, cool wafer, take it out of chamber.
From what little info is in the press release, it doesn't sound like they're doing anything revolutionary, so I'm curious why they claim they can reduce gate leakage by so much.
