Abstract:
1. A method of fabricating a semiconductor p-n junction configured to be disposed between a layer of semiconductor doped with a p-type dopant and a layer of semiconductor doped with an n-type dopant comprising the steps of: growing the semiconductor p-n junction with a crystal growth process that allows simultaneous control and variation of p-type and n-type dopant concentrations during the crystal growth process; dynamically controlling the p-type dopant concentration as the p-n junction is grown such that the p-type dopant concentration conforms to a predetermined concentration profile within the p-n junction which is independent of an p-type dopant diffusion profile; and dynamically controlling the n-type dopant concentration as the p-n junction is grown such that the n-type dopant concentration conforms to a predetermined concentration profile within the p-n junction which is independent of an n-type dopant diffusion profile.
