"COMPUTER CHIPS ARE MADE FROM SILICON, HOW?"

Computer Chips are Made From Silicon, How_2(1)

Silicon is the 14th element on the Periodic Table. Silicon fundamental constituents is,one proton heavier than aluminium and one proton lighter than phosphorus. So it is one of the major component for Computer Processors. After oxygen, it’s the second most abundant element in the Earth’s crust. So we can’t find just around us. It Cannot be find in pure state,virtually comes as a components with other elements. It commonly found as silicate(Sio4) which is one silicon and 4 atom bounds and Silica (Sio2) which is 1 Silicon atom bound with 2 oxygen atoms. Silica, in a rough and highly contaminated form, is the primary component of sand. Feldspar, granite, quartz, and more are all based on silicon-oxygen compounds.

Silicon Components has variety properties that can bind with other atoms tightly in complex arrangements. Silicates like calcium are primary component of Portland cement, the main binder in concrete, mortar, and even stucco. Some silicate-rich materials can be heated to produce hardened ceramics like porcelain, while others will fuse to form the world’s primary form of glass, soda-lime glass.

Silicon is also used for Other trace addictive substance like cast iron,which uses both carbon and silicon to make iron more resilient and less brittle. silicon is also the major structural component of the synthetic material. Conductors have low resistance while electric current can easily pass. While insulators have high resistance, the electrons will be block. For a transistor it require semiconductor to switch on or off. The best semiconductors for industry can be treated with a wide variety of “dopant’s” to finely adjust their resistance, as needed.

Silicon isn’t the only semiconducting substance on Earth which is available in all over the world.We don’t need to export from the African mines. Growing enormous, near-perfect silicon crystals is one of the primary skills in modern computer chip manufacturing. These crystal has been divided into thin wafers,then engraved, processed and treated in different ways before dicing into commercial processors. It’s possible to make superior transistors into carbon and exotic materials like germanium etc.

Silicon crystals are made in 300 mm diameter cylinders, but research is fast approaching the 450mm threshold.These keep the production cost down after that? There might finally be no choice but to abandon silicon for something less abundant and easy to work good news for processing speeds, but almost certainly bad news for your wallet.

Silicon alien life

The core structural molecules that make up our bodies (proteins, amino acids, nucleic acids, fatty acids, and more) are built on skeletons of carbon atoms. This is because carbon has the property called tetravalent. Oxygen can stable two chemical bond and nitrogen has three. Tetra-valency is a powerful basis for building molecules that are both strong and geometrical. If we know the Periodic Table the elements in vertical column has similar properties. This is why science fiction authors have spent so much time and ink of the idea of silicon-based life; being tetravalent itself, silicon is the most plausible alternate structural element in totally novel forms of life. Silicon is happy to bond with other atoms like carbon such that it can be double lock into a single substance.

Silicon is much more abundant on earth than the carbon. It has to be reason that we are organic (carbon) based ,rather than Silicon. And that the reason comes back to periodic table. Elements which are lower than Periodic Table have heavier nuclei and large electron shells. Silicon is larger and heavier than the carbon which is used for recombinant DNA. Silicon is less widely than the carbon such that silicon based life could be less chemically diverse, or require silicon enzymes to force chemically less-desirable compounds into existence.

Silicon is going to pop up the exponential historical trend in computing power technology. It will remains the substance of choice in many fields. At the very least, we are not anywhere near abandoning its use as a building supply, since silicon compounds are the basis for the rock that makes up the vast majority of the Earth’s crust.
