Abstract:
1. A method of healing a defect at a junction of a semiconductor device using germanium (Ge), comprising: 1) growing a p-Ge layer on a substrate; 2) depositing an oxide film on the p-Ge layer, and patterning the oxide film, thus forming a pattern for an n+ Ge region; 3) subjecting the pattern for an n+ Ge region to ion implantation using a n-type dopant, thus forming an n+ Ge region; 4) forming a capping oxide film on the p-Ge layer; 5) performing annealing at 600˜700° C. for 1˜3 hr; and 6) subjecting the capping oxide film to patterning for forming an electrode, depositing the electrode, and performing annealing.
