Intel Friday night unveiled the world's first 45nm processor. The chip isn't just the smalled one available today. More importantly, the company has solved the problem of chip leakage by swapping out some of the materials used to build chips.

The chipmaker furthermore has succeeded in cutting chip leakage without making any drastic changes to its design and production process. It merely swapped out some of the materials that is uses to construct transistors.

In the video below, we take a closer look at the issue of leakage and show how Intel's Penryn processor cuts it.
