computer chips to downsize is not a matter of magic it needs the brains of people like the peter kurtz michelle cursed as an sich a union together as part of an international network they've taken a huge step to even smaller chips. but how computer chips made in the 1st place in principle it takes something like a project into the chip circuitry is stenciled on to the side but instead of projecting the picture on to a screen you focus it onto a silicon wafer with a light sensitive coating plus. the image can then be developed much like a photograph and at the end you have your computer chips. with technology we can go into grade over 16000000000 transistors onto a microchip that's smaller than a fingertip. but what kind of components do we need for a projector we need a light source a and an optical system feet consisting of lenses and mirrors. let's start with a light source light is an electromagnetic wave and waves have a wavelength red light has a long way flanks blue light a short wavelength and ultraviolet light a very short wavelength but what does that have to do with chip manufacture r
