MIT building self-assembling computer chips

Researchers at MIT are working on getting computer chips to "self assemble" by coaxing molecules to arrange themselves into tiny but useful patterns, a process that could lead to microprocessors with much smaller circuit elements.

In the journal Nature Nanotechnology this week, the researchers describe a process that could become an alternative to conventional photolithography, which relies on light projected onto a photo-sensitive material, as people continue to forecast the demise of Moore's Law. That observation states that the number of transistors that can be placed on an integrated circuit doubles roughly every two years.

AMD pays for IBM know-how in battle with Intel

AMD is leaning increasingly on IBM as it battles with Intel for next-generation microprocessor manufacturing leadership. And the payout to IBM is significant.

First some background: On Tuesday, AMD announced that IBM had successfully produced a working test chip using next-generation Extreme Ultra-Violet (EUV) lithography for the critical first layer of metal connections across an entire chip. Previous projects utilizing EUV produced working chip components on only a very small portion of the chip.

Why EUV? The size of transistors and the metal lines that connect them is directly related to the wavelength of light that is used to project … Read more
