    摘要: An electronic device can include a first transistor structure including a first gate electrode surrounded by a first sidewall spacer having a first stress and a second transistor structure including a second gate electrode surrounding a second sidewall spacer having second stress. The first sidewall spacer is an only sidewall spacer surrounding the first gate electrode or a closer sidewall spacer as compared to any other sidewall spacer that surrounds the first gate electrode and the second sidewall spacer is an only sidewall spacer surrounding the second gate electrode or a closer sidewall spacer as compared to any other sidewall spacer that surrounds the second gate electrode, wherein the first stress has a lower value as compared to the second stress. More than one process can be used to form the electronic device.

    摘要: A method of forming an electronic device includes etching a portion of a first gate dielectric layer to reduce a thickness of the gate dielectric layer within that portion. In one embodiment, portions not being etched may be covered by mask. In another embodiment, different portions may be etched during different times to give different thicknesses for the first gate dielectric layer. In a particular embodiment, a second gate dielectric layer may be formed over the first gate dielectric layer after etching the portion. The second gate dielectric layer can have a dielectric constant greater than the dielectric constant of the first gate dielectric layer. Subsequent gate electrode and source/drain region formation can be performed to form a transistor structure.

    摘要: A semiconductor device includes a substrate (12), a first insulating layer (14) over a surface of the substrate (12), a layer of nanocrystals (13) over a surface of the first insulating layer (14), a second insulating layer (15) over the layer of nanocrystals (13). A nitriding ambient is applied to the second insulating layer (15) to form a barrier to further oxidation when a third insulating layer (22) is formed over the substrate (12). The nitridation of the second insulating layer (15) prevents oxidation or shrinkage of the nanocrystals and an increase in the thickness of the first insulating layer 14 without adding complexity to the process flow for manufacturing the semiconductor device (10).

    摘要: Embodiments of the present invention relate to semiconductor structures having multiple gate dielectric structures. One embodiment forms semiconductor devices in multiple regions having different dielectric thicknesses where the interface between the gate dielectric and the semiconductor substrate is protected to result in an improved (e.g. less rough) interface. One embodiment includes forming a dielectric layer overlying a substrate, partially etching the dielectric layer in at least one of the multiple regions, and ashing the dielectric layer. The remaining portion of the dielectric layer (due to the partial etch) may then help protect the underlying substrate from damage during a subsequent preclean. Afterwards, in one embodiment, the gate dielectric layer is grown to achieve a target gate dielectric thickness in at least one of the regions. This may also help further densify the gate dielectric layer. Processing may then be continued to form semiconductor devices in each of the multiple regions.
