From Sand to Processor or How a CPU is made

This article will try to explain how a modern processer (CPU) is made from the sand.
It is hard to believe that a modern processor (CPU) is the most complex product in the world. What is so complex in this piece of metal?
The process of processor manufacturing looks like this: the special equipment is used to grow a mono-crystal of cylindrical shape from the molten silicon. Next, this resulting ingot is cooled and cut into the wafers, which surfaces are carefully leveled and polished to a mirror shine. In the bio-clean rooms of semiconductor factories are created the micro-circuitries on the silicon wafers using photolithography and etching. Then lab personnel make the random testing of processors under a microscope after re-cleaning of the wafers, and if everything is okay, the finished wafers are sliced into individual processors, which later are put in the casing.
