Microchips and how was it created

Tweet

Have you ever wondered how engineer's were able to manufacture microchips that has hundred million transistors on it and how they are able to fit those hundred million transistors on a small wafer chip. Have you ever wondered how they were able to put in 2 CPU's on one die or how were they able to put in 8 SPU's ( SPU's is same as CPU but it handles specific tasks )and 1 CPU ( CPU distributes the tasks on SPU's )on one small microchip. The answer is Extreme Ultraviolet Lithography. The process of making chips will start with a laser light that passes through a xenon gas that will create plasma and the plasma will make electrons that can radiates a light at 13 nanometers ( so short that even the human eye could not see ), then it will go into a condenser that gathers light and will pass through a mask then it will be reflected onto 6 mirrors ( not sure is 6 or 4 ) to reduce the size and then into the wafer chip. I really don't know how were they able to make a machine as awesome as this but the only thing that comes inside my mind is that this technology is so Alienated.. SO what do you guys think?
