Experts say the new nano material or make
computer chips farewell silicon era [introduction] the United States, according to scientists use the new nano material, will create a new type of computer chips, would help to reduce chip manufacturing costs in the future.
American scientists say, the use of new nano materials, will create a new type of computer chips, will help to reduce chip manufacturing costs in the future.
Scientist Gordon e. Moore (Gordon e. Moore) was put forward in 1965, roughly every 18 months, the number of transistors on silicon etching will be doubled.Soon after, critics began to predict "Moore's Law" (Moore 's Law) time will be coming to an end.
More recently, industry experts warn persons: the development of the semiconductor industry is moving towards stagnation, Intel co-founder Dr Moore is going to die.
If so, the computer world will suffer huge impact.Brings the innovation of the personal computers, music players and smart phones, with transistor cost between the rapid decline in direct relationship.On the size of the nails are gathering billions of silicon transistor, computer chips, the cheapest each selling only a few dollars.
But, more optimistic said scientists and engineers, Moore's law is not dead, it's just in evolution., they say, by using a kind of new nano material, vendor may be close to the molecular size of circuit.This type of nano materials including metals, ceramics, polymerization or composite materials, they can be from the "bottom up" from top to bottom instead.
Semiconductor design, for example, researchers are developing some of the chemical process, so that the materials in the semiconductor chip to form a very thin circuit design, to achieve "self-assembly" (self assemble) circuit.Scientists believe that the nanometer circuit design and combine traditional chip manufacturing technology, will produce a new type of computer chips, not only keep Moore's law is valid, but will also reduce chip manufacturing costs in the future.
"Self-assembly is key," SAN jose, California, IBM's Almaden Research Center (Almaden Research Center director of science and technology of chandra plug Carl as Yang (Chandrasekhar Narayan) said."You use the power of nature to help you get the job done. Use brute force doesn't work, you have to work with nature, let things happen naturally."
To do this, semiconductor manufacturers must be from the era of silicon in May be called the "age" of material direction.Researchers in silicon valley is leading the trend, they are using powerful new supercomputers to simulate their predictions.Although the semiconductor chip is no longer made in silicon valley, but here the development of new materials likely over the next decade over the heavens and the earth by changes in the computer world.
"Material is very important for human society," Stanford physicists first zhang sheng said.He led a group of researchers recently devised a tin alloy material, has approximate superconducting properties at room temperature."All the time with
material named - the Stone Age, the iron age, now we have silicon era. In the past, the material is discovered by accident. Once we have the ability to predict material, situation will be different."
Calculate material revolution is likely to be required for developing the next generation computer chip cheap technology specifies a road.
This is the direction of IBM bullish.At present, the company is experimenting with an automatic forming superfine foreign polymer network structure, it can be used in the circuit pattern is formed on a silicon chip.
As Dr Yang this cautious optimism, he said, with a bottom-up self-assembly technology, manufacturers may no longer need to invest in buying new lithography.Lithography using x-rays to etching tiny circuit, price is $500 million (3 billion yuan).
When it comes to use cheaper way to make the circuit more intensive computer chips, he says, "the answer is probably yes."
