    摘要: Embodiments of the invention provide a semiconductor device and a method of manufacture. MOS devices along with their gate electrode sidewall spacers are fabricated such that the orientation of the intrinsic stress in the sidewall spacers is opposite to the stress created in the channel. An embodiment includes selectively patterning a compressive stress layer to form NMOS electrode sidewall spacers, wherein the compressive NMOS electrode sidewall spacers create a tensile stress in a NMOS channel. Another embodiment comprises selectively patterning a tensile stress layer to form tensile PMOS electrode sidewall spacers, wherein the PMOS electrode sidewall spacers create a compressive stress in a PMOS channel. Still other embodiments of the invention provide a semiconductor device having strained sidewall spacers. In one embodiment, a spacer having an intrinsic stress comprising one of tensile and compressive corresponds to a channel stress that is the other of tensile and compressive.

    摘要: A metal-oxide-semiconductor field-effect transistors (MOSFET) having localized stressors is provided. In accordance with embodiments of the present invention, a transistor comprises a high-stress film over the source/drain regions, but not over the gate electrode. The high-stress film may be a tensile-stress film for use with n-channel devices or a compressive-stress film for use with p-channel devices. A method of fabricating a MOSFET with localized stressors over the source/drain regions comprises forming a transistor having a gate electrode and source/drain regions, forming a high-stress film over the gate electrode and the source/drain regions, and thereafter removing the high-stress film located over the gate electrode, thereby leaving the high-stress film located over the source/drain regions. A contact-etch stop layer may be formed over the transistor.

    摘要: Bulk silicon is transformed into an SOI-like structure by annealing. Trenches are formed in a bulk substrate to define device sites. The lower portions of the trenches are annealed at low pressure in a hydrogen atmosphere. This transforms the lower trench portions to expanded, spheroidal voids that extend under the device sites. Neighboring voids each reside about half way under an intervening site. A silicon-consuming process forms a liner on the walls of the voids, with the liners on neighboring voids abutting to isolate the intervening device site from the substrate and other device sites.

    摘要: A new process flow is provided for the creation of a fuse contact and a bond pad. The invention starts with a semiconductor substrate over the surface of which is provided top level metal and fuse metal in the surface of a layer of insulation deposited over the surface of the substrate. A first etch stop layer is deposited over the surface of the layer of insulation over which a first passivation layer is deposited, an opening is created through these layers exposing the top level metal. A metal plug is created overlying the exposed surface of the top level metal. A stack of a patterned and etched hard mask layers, having been deposited at part of the creation of the metal plug and overlying a layer of metal plug material, remains in place over the surface of the created metal plug. A second layer of passivation material is deposited, the second layer of passivation is patterned and etched exposing the surface of the first layer of passivation overlying the fuse metal and exposing the surface of the stack of hard mask layers overlying the created metal plug. The stack of hard mask layers is then removed from the surface of the metal plug, exposing the surface of the metal plug to serve as a contact pad and further reducing the thickness of the first layer of passivation over the surface of the fuse metal, making the fuse more accessible for fuse blowing.

    摘要: A method for forming a dielectric layer provides that a oxidizable substrate has formed thereupon a thermal oxide layer in turn having formed thereupon a deposited nitride layer. The deposited nitride/thermal oxide stack layer is then sequentially: (1) annealed within a nitriding atmosphere; (2) annealed within an oxidizing atmosphere; and (3) treated with a vaporous hydrofluoric acid atmosphere. The annealed and treated stack layer provides, for example, a gate dielectric layer with diminished thickness and enhanced performance.

    摘要: A process for simultaneously forming a first opening to a copper contact structure, and a deeper, second opening, overlying a fuse structure, has been developed. The process features the use of a barrier metal shape, located on a recessed copper contact structure, providing the needed etch stop during a dry etching procedure used to define a first opening in a composite insulator layer. The low etch rate exhibited by the barrier metal shape, in this dry etching environment provides protection of the recessed copper contact structure during the extended dry etching procedure, which is employed to form a deeper, second opening, in thicker dielectric layers, in a region overlying the fuse structure.
