    Look up any of the 7 million websites that describes CMOS (that is complementary metal oxide semiconductor) fabrication and it will show you how diodes are made. Every time you have a p-type/n-type junction you have a diode and cheap diodes are often made using diffusion. When they describe how the wells are diffused in the CMOS process they are describing diode fabrication.

    Advanced diodes also make use of ion implantation to tailor their doping profiles (and therefore their responses).
