Abstract:
1. A method for fabricating a conductive contact, comprising: providing a semiconductor substrate with a dielectric layer formed thereover and two conductive regions and an isolation element formed therein, wherein the isolation element isolates the two conductive regions from each other, and the semiconductor substrate is a p-type substrate and the two conductive regions are n-type regions; forming an opening in the dielectric layer, exposing a top surface of the isolation element and a portion of a top surface of each of the conductive regions; performing an epitaxy process and forming a conductive semiconductor layer within the opening, overlying the top surface of the isolation element and the portion of the top surface of each of the conductive regions; and forming a conductive layer in the opening, overlying the conductive semiconductor layer and filling the opening.
