A nanochip is an integrated circuit ( IC
) that is so small, in physical terms, that individual particles of
matter play major roles. Miniaturization of electronic and computer
components has always been a primary goal of engineers. The smaller an
electronic system can be made, the more processing power can fit into a
given physical volume, the less energy is required to run it, and the
faster it can work (because distances among components are reduced,
minimizing charge-carrier transit time).
The earliest computers, built in the middle of the 20th century, used vacuum tube
s for switching. These machines were so massive and bulky, and demanded
so much electricity to operate, that they required buildings and power
plants of their own. Today, such a computer can be placed inside a
microscopic capsule. The trend toward miniaturization shows no sign of
slowing until some limit is forced on the manufacturing process. The
scale of this limit ultimately depends only on the structure of matter.
Traditional methods of IC manufacture involve etching unwanted semiconductor
material from a preexisting chip, in the same way a sculptor carves a
statue. Futurists suggest that, rather than etching switches and logic gate
s into semiconductor material, chips ought to be mechanically assembled
one molecule at a time. Some scientists believe ICs can be grown from
biological seeds, just as a plant reproduces cells to create a defined
structure such as a tree. Both of these processes involve nanotechnology , and would result in the greatest possible number of switches per unit volume of material substance.
Nanochip is also the name of a nanotechnology
research-and-development corporation based in San Jose, California as
well as the trade name for a molecular biology workstation manufactured
by Nanogen of San Diego, California.
Nano Interconnections
Interconnection is another important part of nano chips.
This involves the logical and mathematical operations and the wiring
between the transmitters to make their interaction possible. Nanotubes and wires as narrow as one nanometer are used to link the
transistors together. Some transistors have nanowires in them.
Nano Architecture
Architecture involves the way that the transistors are interconnected.
The circuit can then plug into a computer or other system and operate independently of the lower-level details.
Although they are destined for errors and defects, the architecture
has built-in redundancy and interconnections with the ability to
reconfigure structures at several levels on a chip. The redundancy
helps avoid more problems and errors in the system.
