Chips Push Through Nano-Barrier

Posted January 28, 2007 4:46 PM

From BBC News | Science/Nature | UK Edition:

The next milestone in the relentless pursuit of smaller, higher performance microchips has been unveiled. Chip-maker Intel has announced that it will start manufacturing processors using transistors just 45 nanometres (billionths of a metre) wide. Shrinking the basic building blocks of microchips will make them faster and more efficient. Computer giant IBM has also signalled its intention to start production of chips using the tiny components. "Big Blue", which developed the transistor technology with partners Toshiba, Sony and AMD, intends to incorporate them into its chips in 2008. Intel said it would start commercial fabrication of processors at three factories later this year.

Something is not adding up here.

If they can build a transistor that is 45 nm across then on a 1 cm2 chip, roughly half the size of a postage stamp, then you can fit something like 49 billion transistors. They are however claiming that they can only fit 400 million semiconductors and that adds up to a spacing of 200 nm.

What is going on?

Circuitry, ie, power busses, signal paths, clock lines, etc. plus a certain amount of spacing for electrical isolation take up a lot of the chip's real estate but I do agree there seems to be a lot of available space.
