SUMMARY
Ion implantation and diffusion are critical processes in wafer fabrication. Ion implantation involves accelerating ions in an electric field and impacting them into silicon wafers to modify their properties. Diffusion, on the other hand, is the process of introducing impurities into the wafer surface by heating, allowing atoms to move and alter conduction properties. Doping refers specifically to the addition of impurities to create N-type or P-type conductors. Understanding these processes is essential for semiconductor device fabrication.
