How does mobile processor made?

What does mobile processor contain?

The costliest thing in the electrical gadget is processor. From which material the processor is made is sand. This and is not that present around us. Its silica sand which is very costly. Some third party companies sell these sand to the process making companies.

As silica is the the best semiconductor so it is used for making the processor. The sand should contain 25% of silica. Now the present making companies melt and and separate the sand and melt and separate silica from it which requires high temperature and the silica is highly purified. This purified silica is made into cylindrical shape.

This cylindrical box will be cutted into slices. After the slices will be polished with photo sensitive chemicals after that slices will be formed as a disc.

Before this the process engineer will design the the blueprint of the processor famous companies is ARM. The blueprint contains how many transistors should be required and the the nanometre size between the transistors etc.

Then through ultraviolet rays scientist print the blueprint on the disc after that it it will be watched and clean then layer-by-layer transistors are fixed to the disc layer-by-layer.

Then step by step fixing the transistors processor is made. There are many other more technical steps to prepare processor but its very depth know.

Many more precautions what taken for the above process scientist on suits no dust because the transistor size is less than our hair particle. This is the practical knowledge about processor which is made of sand.
