    摘要: An interconnect structure is provided in which the conductive features embedded within a dielectric material are capped with a metallic capping layer, yet no metallic residue is present on the surface of the dielectric material in the final structure. The inventive interconnect structure has improved dielectric breakdown strength as compared to prior art interconnect structures. Moreover, the inventive interconnect structure has better reliability and technology extendibility for the semiconductor industry. The inventive interconnect structure includes a dielectric material having at least one metallic capped conductive feature embedded therein, wherein a top portion of said at least one metallic capped conductive feature extends above an upper surface of the dielectric material. A dielectric capping layer is located on the dielectric material and it encapsulates the top portion of said at least one metallic capped conductive feature that extends above the upper surface of dielectric material.

    摘要: In producing complementary sets of metal-oxide-semiconductor (CMOS) field effect transistors, including nMOS and pMOS transistors), carrier mobility is enhanced or otherwise regulated through the use of layering various stressed films over either the nMOS or pMOS transistor (or both), depending on the properties of the layer and isolating stressed layers from each other and other structures with an additional layer in a selected location. Thus both types of transistors on a single chip or substrate can achieve an enhanced carrier mobility, thereby improving the performance of CMOS devices and integrated circuits.

    摘要: A low k stress liner, which replaces conventional stress liners in CMOS devices, is provided. In one embodiment, a compressive, low k stress liner is provided which can improve the hole mobility in pFET devices. UV exposure of this compressive, low k material results in changing the polarity of the low k stress liner from compressive to tensile. The use of such a tensile, low k stress liner improves electron mobility in nFET devices.

    摘要: A stressed film applied across a boundary defined by a structure or a body (e.g. substrate or layer) of semiconductor material provides a change from tensile to compressive stress in the semiconductor material proximate to the boundary and is used to modify boron diffusion rate during annealing and thus modify final boron concentrations. In the case of a field effect transistor, the gate structure may be formed with or without sidewalls to regulate the location of the boundary relative to source/drain, extension and/or halo implants. Different boron diffusion rates can be produced in the lateral and vertical directions and diffusion rates comparable to arsenic can be achieved. Reduction of junction capacitance of both nFETs and pFETs can be achieved simultaneously with the same process steps.
