Diodes are primarily made through the processes of diffusion and ion implantation, particularly in the context of CMOS (Complementary Metal Oxide Semiconductor) fabrication. A diode is formed at every p-type/n-type junction, which is a fundamental aspect of semiconductor technology. The diffusion process is commonly used for creating inexpensive diodes, while ion implantation allows for precise control over doping profiles, enhancing diode performance. Resources detailing CMOS fabrication provide comprehensive insights into these methods.
PREREQUISITESElectronics engineers, semiconductor manufacturers, and students studying materials science or electrical engineering will benefit from this discussion on diode fabrication methods.
allright...I will search for thiscarlgrace said: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).
