You can start here.... iSuppli....but it really depends on what you consider wafers are used for, big box machines and/or phone and tablet chips.

Thanks.

I don’t care what its used for. I was just curious how many wafers were produced(for all electronics) and where they were produced. I suppose it would be easier to measure it in pounds of monocrystaline silicon cylindrical ingot produced per annum of...say the top ten nations. I have a hunch over 50% of it is produced in north america and at least 25% produced in japan...but I could be wrong.

Your link indicates dollars of sales but it doesn’t say what of. I assume those sales are of finished CPUs, RAM, ROM, ePROM, GPUs, microcontrollers of all kinds, and photovoltaics, and other...plus equipment sold for fabrication of silicon based circuits at every step of the way. I would guess the german company on that list is heavy on the sales of machines for the fabrication of wafers and whatever optics are used. Germans tend to excel in such industries.

LOOK WHAT I FOUND

Do you know if ingots are produced in the same plant that etches the chips on the wafers?
