ZDNet India : Life after Moore's Law

Moore's Law, as chip manufacturers generally refer to it today, is coming to an end, according to a recent research paper. Manufacturers will be able to produce chips on the 16-nanometer manufacturing process, expected by conservative estimates to arrive in 2018, and maybe one or two manufacturing processes after that, but that's it.

.... When current flows from the source to the drain, a computer reads this as a "1." When current is not flowing, the transistor is read as a "0." Millions of these actions together produce the data inside PCs. Strict control of the gate and channel region, therefore, are necessary to produce reliable results.

When the length of the gate gets below 5 nanometers, however, tunneling will begin to occur. Electrons will simply pass through the channel on their own, because the source and the drain will be extremely close....
