    摘要: In sophisticated semiconductor devices, non-insulating materials with extremely high internal stress level may be used in the contact level in order to enhance performance of circuit elements, such as field effect transistors, wherein the non-insulating material may be appropriately “encapsulated” by dielectric material. Consequently, a desired high strain level may be obtained on the basis of a reduced layer thickness, while still providing the insulating characteristics required in the contact level.

    摘要: A semiconductor structure comprises a transistor element formed in a substrate. A stressed layer is formed over the transistor element. The stressed layer has a predetermined tensile intrinsic stress of about 900 MPa or more. Due to this high intrinsic stress, the stressed layer exerts considerable elastic forces to the channel region of the transistor element. Thus, tensile stress is created in the channel region. The tensile stress leads to an increase of the electron mobility in the channel region.

    摘要: A semiconductor structure comprises a transistor element formed in a substrate. A stressed layer is formed over the transistor element. The stressed layer has a predetermined compressive intrinsic stress having an absolute value of about 1 GPa or more. Due to this high intrinsic stress, the stressed layer exerts considerable elastic forces to the channel region of the transistor element. Thus, compressive stress is created in the channel region. The compressive stress leads to an increase of the mobility of holes in the channel region.

    摘要: Reliably capped Cu interconnects are formed with a significant reduction in the amount and size of hillocks by reducing the time during which the Cu interconnect is exposed to elevated temperatures for plasma surface treatment and capping layer deposition. Embodiments of the present invention include maintaining a continuous plasma during surface treatment to remove copper oxide and capping layer deposition, and exposing the wafer to elevated temperatures to no greater than 60 seconds in the reaction chamber.
