Currently, the gate length, the characteristic length parameter in transistors, has hit about 90 nm. The shorter the gate length, the faster transistors can switch on and off. In fact, the transistors have gotten so fast, that the delay as electrons flow through the skinnier and longer wires needed to cross larger, complex chips is on track to become the limiting factora in speed. This delay is just one of the fundamental problems that threatens to make the nanoscale regime of electronics unfaithful to Moore's Law and demands the design of new materials and structures or a complete shift in chip architecture.

Best Regards, archibold dorothy Materials: Carbon Nanotubes Dr. Hongjie Dai, Chemistry Slice a layer of pencil lead, roll it up, and you have a carbon nanotube: a graphene sheet (a layer of graphite) rolled up into a cylinder. "A carbon nanotube is a clever way of making a fully saturated nanowire structure-a 1-D structure with all its atoms fully bonded," explains Professor Dai, who has developed catalysts that control where carbon nanotubes grow. "The big challenge is controlling the synthesis. More control leads to definite physical properties," says Dai. In contrast to conventional semi-conductors, where "the surface atoms are not happily bonded," as Dai puts it, the high degree of structural perfection in nanotubes leads to ballistic transport of electrons, which translates into high speed electronics. Dai predicts that while it is doubtful that carbon nanotubes will overtake the electronics industry, it is quite possible that they will replace some electronics components. Currently, the gate length, the characteristic length parameter in transistors, has hit about 90 nm. The shorter the gate length, the faster transistors can switch on and off. In fact, the transistors have gotten so fast, that the delay as electrons flow through the skinnier and longer wires needed to cross larger, complex chips is on track to become the limiting factora in speed. This delay is just one of the fundamental problems that threatens to make the nanoscale regime of electronics unfaithful to Moore's Law and demands the design of new materials and structures or a complete shift in chip architecture. A decade ago, Saraswat's research group was the first to begin developing a new kind of chip architecture: the 3-dimensional integrated circuit (3-D IC). Compared to the 2-D planar chips in computers today, 3-D chips can provide the same processing power with a reduced chip surface area. Also, instead of having long, twisting highways of wires, the stacked chips in 3-D ICs allow for short wires much like elevator shafts, as Professor Chidsey puts it-mitigating the problem of delay in the wires. Moreover, 3-D IC architecture allows the integration of all kinds of chips, since chips that require different technologies or materials can be stacked together. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
