diffusion and ion implantation in fabrication

[vead]

look at this definitions Is it correct ?


Ion implantation and diffusion both process is used to add impurity into wafer surface


Diffusion is process by which atom of material are deposited on to the surface of wafer at high temperature


Movement of atom form source to wafer at high temperature


Ion implantation is process by which ion of material deposited on to wafer surface


Ion of material accelerate in electric field and deposited into wafer surface

looks OK, what did you think was the problem ?

There's a wealth of info available on the net as to the processes used
