| 摘要 |
The present invention relates to a semiconductor device comprising a homojunction or a heterojunction with a controlled dopant (concentration) profile and a method of making the same. Accordingly, one aspect of the invention is a method for manufacturing a junction comprising forming a first semiconductor material comprising a first dopant having a first concentration and thereupon; forming a second semiconductor material comprising a second dopant, having a second concentration thereby forming a junction, and depositing by Atomic Layer Epitaxy or Vapor Phase Doping at least a fraction of a monolayer of a precursor suitable to form the second dopant on the first semiconductor material, prior to forming the second semiconductor material, thereby increasing the second concentration of the second dopant at the junction.
