IBM has advanced the technology of silicon photonics, fabricating a microchip that has built-in components to send and receive data over optical links.

Researchers have built optical data links into chips before, but IBM's move is notable because it uses conventional chipmaking equipment geared for chips with 90-nanometer features. Today's chips use metal wires to exchange data, but optical links offer the potential of higher transfer speeds over longer distances.

The chip can include several optical components including wavelength division multiplexers that let the chip send and receive signals with multiple frequencies of light, an approach that lets … Read more

First of all, don't panic.

If Moore's Law came to an end and computers stopped getting steadily faster, plenty of companies would suffer. But an end likely would come with lots of warning, lots of measures to cushion the blow, and lots of continued development even if transistors stopped shrinking.

The hardest hit would be companies dependent on consumers replacing their electronics every few years and tech companies such as Google whose long-term plans hinge on faster computers, cheaper storage, and better bandwidth. And the continuing miniaturization of computers -- mainframes to minicomputers to PCs to smartphones -- … Read more

Mike Mayberry, perhaps more than anyone, is the guy who keeps Moore's Law ticking.

As the vice president who leads Intel's research team, he bears responsibility for making sure his employer can cram ever more electronic circuitry onto computer chips. Intel co-founder Gordon Moore 47 years ago observed the pace at which microchips' transistor count doubled, and Mayberry is in charge of keeping that legacy intact.

A lot rests on Moore's Law, which in a 1975 update to Moore's original 1965 paper predicted that the number of transistors will double every two years. That means a … Read more

Year in, year out, Intel executive Mike Mayberry hears the same doomsday prediction: Moore's Law is going to run out of steam. Sometimes he even hears it from his own co-workers.

But Moore's Law, named after Intel co-founder Gordon Moore, who 47 years ago predicted a steady, two-year cadence of chip improvements, keeps defying the pessimists because a brigade of materials scientists like Mayberry continue to find ways of stretching today's silicon transistor technology even as they dig into alternatives. (Such as, for instance, super-thin sheets of carbon graphene.)

Oh, and don't forget the money that'… Read more

Victor Poor, one of the founding fathers of early computer innovation, died Friday at the age of 79. He was one of the handful of engineers who helped develop Intel's first single chip microprocessor -- the 4004. Poor continued to be instrumental in microprocessor and computer advancement throughout his life.

According to the New York Times, Poor died of pancreatic cancer in Palm Bay, Fla.

Poor, who was a self-taught engineer, began working with Intel in 1969 when he met with well-known engineer Stanley Mazor to discuss the idea of building a processor for a programmable terminal, according to … Read more

Researchers are getting down to the atomic level in the pursuit of smaller and more powerful computers.

The University of New South Wales in Australia today announced it has made a single-atom transistor using a repeatable method, a development that could lead to computing devices that use these tiny building blocks.

About two years ago, a team of researchers from the Helsinki University of Technology, the University of New South Wales, and the University of Melbourne in Australia announced the creation of a single-atom transistor designed around a single phosphorus atom in silicon.

Now a new paper published in the … Read more

Bad news for anybody in the business of making the chips that power PCs and store movies on iPads.

IHS today said it's dramatically reduced its forecast for semiconductor sales worldwide for 2011, cutting the expected growth rate from 2.9 percent all the way down to 1.2 percent. The industry has swung from boom to bust many times in its decades of existence, but hard times still have the same unpleasant ripple effects: less money to fund research into next-generation products and to pay for next-generation manufacturing facilities.

And it's those investments that ultimately matter to … Read more

Shipments of PC processors failed to gain ground during the second quarter, but revenue still inched its way higher, according to data out today from IDC.

For the quarter, worldwide chip shipments rose only 0.6 percent from a year ago and fell 2.9 percent from the first quarter. Sales reached $9.49 billion, a 5.4 percent rise from 2010's second quarter but a 4 percent drop from the first quarter.

"The first quarter of 2011 was better than most first quarters due to the extra calendar week," Shane Rau, director of Semiconductors: Personal Computing … Read more

In 2010, semiconductors brought in record revenue of $298.3 billion worldwide, a jump of 31.8 percent compared with the previous year, according to data out yesterday from the Semiconductor Industry Association.

In addition, chip sales in December hit $25.2 billion, a gain of 12.2 percent compared with 2009's final month. Fourth-quarter revenue grew the same percentage from the year-ago quarter to reach $75.5 billion.

"Semiconductor sales are a bright spot in our current economic picture, delivering a record high in the billions," SIA President Brian Toohey said in a statement. "The … Read more
