    摘要: A method of manufacturing a semiconductor device comprising removing a first oxide layer deposited over a semiconductor substrate, thereby exposing source and drain regions of the substrate. The first oxide layer is configured as an etch-stop for forming silicon nitride sidewall spacers of a gate structure located adjacent to the source and drain regions. The method further comprises depositing a second oxide layer selectively on the exposed source and drain regions and then removing lateral segments of the silicon nitride sidewall spacers.

    摘要: A silicon nitrate layer (110) is formed over a transistor gate (40) and source and drain regions (70). The as-formed silicon nitride layer (110) comprises a first tensile stress and a high hydrogen concentration. The as-formed silicon nitride layer (110) is thermally annealed converting the first tensile stress into a second tensile stress that is larger than the first tensile stress. Following the thermal anneal, the hydrogen concentration in the silicon nitride layer (110) is greater than 12 atomic percent.

    摘要: A complementary metal oxide semiconductor (CMOS) device has a substrate 100, a gate structure 108 disposed atop the substrate, and spacers 250, deposited on opposite sides of the gate structure 108 to govern formation of deep source drain regions S, D in the substrate. Spacers 250 are formed of an oxynitride (SiOxNyCz) wherein x and y are non-zero but z may be zero or greater; such oxynitride spacers reduce parasitic capacitance, thus improving device performance. A method of fabricating a portion of a complementary metal oxide semiconductor (CMOS) device involves providing a substrate 100, forming a gate structure 108 over the substrate, depositing a first layer 104 atop the substrate on opposite sides of the gate structure to govern formation of deep source drain regions in the substrate, depositing an oxynitride (SiOxNyCz) layer 250 atop the first layer (in which x and y are non-zero but z may be zero or greater), depositing a second layer 112 atop the oxynitride layer, and depositing a nitride layer 114B atop the second layer.
