SAN JOSE, Calif. — IBM Corp. and the Georgia Institute of Technology Tuesday (June 20) claimed they have broken the silicon speed record, thanks in part to a "frozen chip."
IBM (Armonk, N.Y.) and Georgia Tech (Atlanta) claimed that they have demonstrated the first silicon-based chip capable of operating at frequencies above 500 GHz by cryogenically "freezing" the circuit to minus 451 degrees Fahrenheit (4.5 Kelvins).
By comparison, 500 GHz is more than 250 times faster than today's cell phones, which typically operate at approximately 2 GHz, according to the organizations.
The experiments, conducted jointly by IBM and Georgia Tech, are part of a project to explore the ultimate speed limits of silicon germanium (SiGe) devices, which are said to operate faster at cold temperatures.
Ultrahigh-frequency SiGe circuits have potential applications in commercial communications systems, military electronics, space and remote sensing. The research could make possible a new class of powerful, low-energy chips that will deliver future applications like HDTV and movie-quality video to cellphones, automobiles and other devices.
The chips used in the research are from a prototype fourth-generation SiGe technology fabricated by IBM on 200-mm wafers. At room temperature, the circuits operated at approximately 350 GHz.
"For the first time, Georgia Tech and IBM have demonstrated that speeds of half a trillion cycles per second can be achieved in a commercial silicon-based technology, using large wafers and silicon-compatible low-cost manufacturing techniques," John Cressler, Byers Professor in Georgia Tech's School of Electrical and Computer Engineering, and a researcher in the Georgia Electronic Design Center at Georgia Tech, said in a statement.
"This groundbreaking collaborative research by Georgia Tech and IBM redefines the performance limits of silicon-based semiconductors," Bernie Meyerson, vice president and chief technologist at IBM Systems and Technology Group, said in the same statement.
In addition to Cressler, the team included Georgia Tech PhD students Ramkumar Krithivasan and Yuan Lu; Jae-Sun Rieh of Korea University in Seoul (formerly with IBM); and Marwan Khater, David Ahlgren and Greg Freeman of IBM Microelectronics (East Fishkill, N.Y.) The accomplishment will be reported in the July issue of the journal IEEE Electron Device Letters.

10 emerging technologies to watch:
EE Times has compiled a list of emerging technologies that we think will be worth watching out for in 2010. Biofeedback or thought-control of electronics are among the contenders.
10 CEOs out in 2009:
It's been a tough year for the global electronics industry and CEOs. We survey the dismissal of 10 industry CEOs during the first three quarters of 2009 and what's ahead for the rest of the year.
Executive pay:
The economy stinks. Rank-and-file engineers are feeling the pain. What about technology CEOs? We crunched the numbers buried in corporate financial statements to find out. Here's what we found.
10 companies in trouble (revisited):
What follows is an updated version of 10 companies in trouble. Some companies have been removed since the last version, others remain. Still others have been added to the mix.
Early predictions for 2010:
The electronics industry is recovering, but there is still some uncertainty in the market. Some see a boom year in 2010. Some see a double dip. So what's in store for the rest of this year and 2010?
Top 10 IC vendors with cash:
The world's biggest IC companies by revenue rank not only among the best in their respective industry segments but are also more likely to have huge piles of cash that can be used to fund acquisitions, R&D and product development.
Notable women in microelectronics:
There is no better time than a global economic recession to examine the keys to successful corporate governance. So, EE Times has compiled an international list that celebrates women who are business and technology leaders in semis.
EE Times updates Silicon 60:
Seventeen companies have been added to the lastest version of our Silicon 60 list of emerging startups. Forty-three companies survived as emerging companies that are still worth watching.
