How to Make a Microprocessor

This is a live demonstration from the 2008 Royal Institution Christmas Lectures illustrating the concept of photo reduction, by projecting the initials of a volunteer onto a grain of rice. This technique forms the basis for photolithography which is used to manufacture microprocessors.

You can watch the 2008 Royal Institution Christmas Lectures in full at: http://research.microsoft.com/~cmbishop or by visiting the Royal Institution web site.

There is a dedicated web site to accompany the 2008 Christmas Lectures, with ten interactive games as well as downloadable PDF instructions for experiments which can be conducted at home or at school: http://www.rigb.org/christmaslectures08

Well I think it's wonderful that teaching the children about how microprocessors are made is a very good idea for children to get in to technology. This does help them understand how technology works for everyday living.

lots of simple things make something very complex :)

Now i know how to see my Hand on a Piece of Rice, but not how to make a Micro Processor.

@NickBlackDIN Indeed. I have long said that complexity is the redundancy of simplicity. Think about it. ;)

[SVBerk65]

So THATS how they do it!!!!

Just like that, except you replace the rice with a silicon wafer. Then you project a circuit diagram onto it. It's called Photolithographic.

Photolithography at work

why are they made on circles and not squares

@Chihang256 First think about what a microprocessor does: Addition, Subtraction, comparison, and so on.Then depending on the current states decides which parts to use. All this is done by among other transistors.

intersting and simple. I always wondered how they make it so tiny and now I know. But microprocessors are simply gar more than that. Its not so much important how its made, but how do they work.

[Chihang256]

So how do you make a micro prosecessor??

Super  !
