SEMI CONDUCTORS IN NANOTECHNOLOGY




troduction:
Nanotechnology is a multitude of rapidly emerging technologies, based upon the scaling down of existing technologies to the next level of precision and miniaturization. The original vision for nano technology is sometimes termed “Molecular manufacturing” or “molecular manufacturing based technology”. Nanotechnology is about building things atom by atom, molecule by molecule. Nanotechnology is providing a nanometer scale at which hydrogen and carbon atoms are picked up and by assembling them a machine is built, called “nano machine”. A nanometer is a billionth of a meter, i.e. about 1/80,000th of the diameter of a human hair, or ten times the diameter of a hydrogen atom. If you measure the width of ten atoms placed side by side you would have a nanometer. By application of these machines bringing about a great improvement in all fields of human being.

What is nano-technology?

The goal of early nanotechnology was to produce the first nano-size robotic arm capable of manipulating atoms and molecules either into a useful product or copies of itself. This is because manufacturing is basically a method for arranging atoms. Most methods arrange atoms crudely – even the finest commercial microchips are grossly irregular at the atomic scale, and much of today’s nanotechnology faces the same challenge.

The molecular assembler is the answer to this challenge. Once perfected, it will position the molecules, bringing them together to the specific location and at the desired time. By holding and positioning molecules in this way, the molecular assemblers will control with precision how the molecules react, building up complex structures that finally lead to the desired product. Atoms and molecules stick together because they have complementary shapes that lock together or charges that attract. Just like magnets, a positively charged atom will stick to a negatively charged atom. As millions of these atoms are pieced together by nano-machines, a specific product will begin to take shape. The goal of nanotechnology is to manipulate atoms individually and place them in a pattern to produce a desired structure.
