摘要： Embodiments of a method for fabricating an integrated circuit are provided. In one embodiment, the method includes producing a partially-completed semiconductor device including a substrate, source/drain (S/D) regions, a channel region between the S/D regions, and a gate stack over the channel region. At least one raised electrically-conductive structure is formed over at least one of the S/D regions and separated from the gate stack by a lateral gap. The raised electrically-conductive structure is then back-etched to increase the width of the lateral gap and reduce the parasitic fringing capacitance between the raised electrically-conductive structure and the gate stack during operation of the completed semiconductor device.

摘要： A method of fabricating a semiconductor device structure begins by forming a layer of oxide material overlying a first gate structure having a first silicon nitride cap and overlying a second gate structure having a second silicon nitride cap. The first gate structure corresponds to a p-type transistor to be fabricated, and the second gate structure corresponds to an n-type transistor to be fabricated. The method continues by performing a tilted ion implantation procedure to implant ions of an impurity species in a channel region of semiconductor material underlying the first gate structure, during which an ion implantation mask protects the second gate structure. Thereafter, the ion implantation mask and the layer of oxide material are removed, and regions of epitaxial semiconductor material are formed corresponding to source and drain regions for the first gate structure. Thereafter, the first silicon nitride cap and the second silicon nitride cap are removed.
