Part II: Semiconductor roadmap looks at nanotechnology

The International technology roadmap for Semiconductors2005 edition Emergy Research devices http://www.itrs.net/Common/2005ITRS/ERD2005.pdf There is an very interesting technology performance assessment pg48-55Nano-floating gate memory(pg50), engineered tunnel barriermemory(pg50), 1D logic structures (pg53) (carbon nanotubes andnanowires) seem to be the leading candidates based on this assessment. Table 55 on page 8compares the current technology capabilities in 2005 andthe projected …

Part I : Semiconductor technology roadmap for 2005 – considers emerging nanotech

By the naming convention of these roadmaps…NEMS is rod logic. The emerging research devices section considers molecular devices, rod logic systems, nanotubes and nanowires and other nanotechnology related technology. Page 44 of the emerging research devices section. They define nano-electro-mechanical systems (NEMS) as rod logic.They have a conservative estimate of rod logic performance.They also assume …

Gold nanospheres show a path to all-optical computing.

New research, however, may enable engineers to build nanoscale antennae that turn light into a different sort of wave that can move through metal; the result could be data transmission speeds that are orders of magnitude higher than today’s. The key to the approach is a gold sphere just 50 nanometers in diameter. A Rice …

DNA self-assembly used to mass-produce patterned nanostructures

Duke University scientists have used the self-assembling properties of DNA to mass-produce nanometer-scale structures in the shape of a 4×4 grids, on which patterns of molecules can be specified. They said the achievement represents a step toward mass-producing electronic or optical circuits at a scale 10 times smaller than the smallest circuits now being manufactured. …

Richard Jones lays out the hurdles to his belief in Diamondiod nanotechnology

Richard Jones has proposed 6 experiments for validating his belief in diamondoid nanotechnology 1. Stability of nanoclusters and surface reconstruction.2. Thermal noise, Brownian motion and tolerance.3. Friction and energy dissipation.4. Design for a motor.5. The eutactic environment and the feed-through problem.6. Implementation path. It seems that Richard Jones has clearly outlined his areas of concern …

DNA wires made and formed into patterns

Ohio State University researchers have invented a process for uncoiling long strands of DNA and forming them into precise patterns. Ultimately, these DNA strands could act as wires in biologically based electronics and medical devices They used a tiny rubber comb to pull DNA strands from drops of water and stamp them onto glass chips. …

Other technology: plastic circuits, pre-nano desktop manufacturing

At Sarnoff Corporation in Princeton, NJ, and Columbia University, researchers have succeeded in operating circuits at 100 megahertz — as much as a hundred times faster than previous ones on plastic. The Sarnoff/Columbia advance could lead to displays measuring three meters or more diagonally that can also be rolled up and easily transported. 10-100 times …
