  • Publication number: 20070269970
    Abstract: The present invention provides a semiconductor device comprising at least one field effect transistor (FET) having source and drain (S/D) metal silicide layers with intrinsic tensile or compressive stress. First, a metal layer containing a silicide metal M is formed over S/D regions of a FET, followed by a first annealing step to form S/D metal silicide layers that comprise a metal silicide of a first phase (MSix). A silicon nitride layer is then formed over the FET, followed by a second annealing step. During the second annealing step, the metal silicide is converted from the first phase (MSix) into a second phase (MSiy) with x<y. The metal silicide conversion causes either volumetric shrinkage or expansion in the S/D metal silicide layers of the FET, which in turn generates intrinsic tensile or compressive stress in the S/D metal silicide layers under confinement by the silicon nitride layer.

  • Patent number: 7287325
    Abstract: Disclosed are a damascene and dual damascene processes both of which incorporate the use of a release layer to remove trace amounts of residual material between metal interconnect lines. The release layer is deposited onto a dielectric layer. The release layer comprises an organic material, a dielectric material, a metal or a metal nitride. Trenches are etched into the dielectric layer. The trenches are lined with a liner and filled with a conductor. The conductor and liner materials are polished off the release layer. However, trace amounts of the residual material may remain. The release layer is removed (e.g., by an appropriate solvent or wet etching process) to remove the residual material. If the trench is formed such that the release layer overlaps the walls of the trench, then when the release layer is removed another dielectric layer can be deposited that reinforces the corners around the top of the metal interconnect line.

  • Publication number: 20070210448
    Abstract: A semiconductor structure that includes a Co-containing liner disposed between an oxygen-getter layer and a metal-containing conductive material is provided. The Co-containing liner, the oxygen-getter layer and the metal-containing conductive material form MOL metallurgy where the Co-containing liner replaces a traditional TiN liner. By “Co-containing” is meant that the liner includes elemental Co alone or elemental Co and at least one of P or B. In order to provide better step coverage of the inventive Co-containing liner within a high aspect ratio contact opening, the Co-containing liner is formed via an electroless deposition process.

  • Publication number: 20070171549
    Abstract: A focusing module includes a casing, at least one fixed magnetic element, a membrane, a movable magnetic element, and a lens. The fixed magnetic element is fixed in the casing for generating a first magnetic field. The membrane is received and retained in an upper section of the casing. The membrane defines a central hole. The movable magnetic element is attached to the membrane, surrounding the central hole of the membrane. The movable magnetic element receives a control signal and in response thereto generates a second magnetic field, which interacts with the first magnetic field of the fixed magnetic field to induce a force acting on the membrane to cause elastic deformation of the membrane. The lens is fixed to the central hole of the membrane whereby the lens is movable with respect to the casing due to the elastic deformation of the membrane caused by magnetic interaction between the first and second magnetic fields of the fixed and movable magnetic elements so as to effect focusing operation.

  • Patent number: 7241696
    Abstract: Disclosed is a method for depositing a metal layer on an interconnect structure for a semiconductor wafer. In the method, a metal conductor is covered by a capping layer and a dielectric layer. The dielectric layer is patterned so as to expose the capping layer. The capping layer is then sputter etched to remove the capping layer and expose the metal conductor. In the process of sputter etching, the capping layer is redeposited onto the sidewall of the pattern. Lastly, at least one layer is deposited into the pattern and covers the redeposited capping layer.

  • Publication number: 20070148958
    Abstract: An interconnect structure in which the adhesion between an upper level low-k dielectric material, such as a material comprising elements of Si, C, O, and H, and an underlying diffusion capping dielectric, such as a material comprising elements of C, Si, N and H, is improved by incorporating an adhesion transition layer between the two dielectric layers. The presence of the adhesion transition layer between the upper level low-k dielectric and the diffusion barrier capping dielectric can reduce the chance of delamination of the interconnect structure during the packaging process. The adhesion transition layer provided herein includes a lower SiOx- or SiON-containing region and an upper C graded region. Methods of forming such a structure, in particularly the adhesion transition layer, are also provided.

  • Patent number: 7208414
    Abstract: The present invention provides a method for enhancing uni-directional diffusion of a metal during silicidation by using a metal-containing silicon alloy in conjunction with a first anneal in which two distinct thermal cycles are performed. The first thermal cycle of the first anneal is performed at a temperature that is capable of enhancing the uni-directional diffusion of metal, e.g., Co and/or Ni, into a Si-containing layer. The first thermal cycle causes an amorphous metal-containing silicide to form. The second thermal cycle is performed at a temperature that converts the amorphous metal-containing silicide into a crystallized metal rich silicide that is substantially non-etchable as compared to the metal-containing silicon alloy layer or a pure metal-containing layer. Following the first anneal, a selective etch is performed to remove any unreacted metal-containing alloy layer from the structure.

  • Publication number: 20070087541
    Abstract: Disclosed is a method and structure for forming a silicide on a silicon material. The invention places the silicon material in a vacuum environment, forms metal on the silicon material, and then heats the silicon surface and the metal without breaking the vacuum environment. The processes of forming the metal and heating the silicon can be performed simultaneously without breaking the vacuum environment to form the silicide as the metal is being deposited. After the foregoing processing, the invention can remove the silicon surface from the vacuum environment and perform additional heating of the silicon surface. The first heating process forms a monosilicide and the additional heating forms a disilicide.
