Abstract:
1. A method of forming a semiconductor device, the method comprising: forming a gate portion on a surface of a semiconductor substrate, the gate portion having gate sidewalls; forming gate spacers on the gate sidewalls and on the surface of the semiconductor substrate, the gate spacers having first sidewalls opposite the gate sidewalls; forming raised source/drain (RSD) regions on the surface of the semiconductor substrate, the RSD regions having a faceted side portion contacting the gate spacers at the surface of the semiconductor substrate, thereby forming cavity regions defined by the first sidewalls and the faceted side portion of the RSD regions; filling the cavity regions with a dielectric material, thereby forming dielectric regions; and forming second spacers on the first sidewalls and on a top surface of the dielectric regions, the second spacers having second sidewalls.
