Abstract:
Disclosed is a semiconductor article which includes a semiconductor substrate; a gate structure having a spacer adjacent to a conducting material of the gate structure wherein a corner of the spacer is faceted to create a faceted space between the faceted spacer and the semiconductor substrate; and a raised source/drain adjacent to the gate structure, the raised source/drain filling the faceted space and having a surface parallel to the semiconductor substrate. Also disclosed is a method of making the semiconductor article.
