  • Patent number: 7977182
    Abstract: Described herein is a method of manufacturing a semiconductor device realizing higher performance by reducing contact resistance of an electrode. In the method, a gate insulating film, a gate electrode are formed on a semiconductor substrate. A first metal is deposited substrate, and a metal semiconductor compound layer is formed on the surface of the semiconductor substrate by making the first metal and the semiconductor substrate react each other by a first heat treatment. Ions having a mass equal to or larger than atomic weight of Si are implanted into the metal semiconductor compound layer. A second metal is deposited on the metal semiconductor compound layer. An interface layer is formed by making the second metal segregated at an interface between the metal semiconductor compound layer and the semiconductor substrate by diffusing the second metal through the metal semiconductor compound layer by a second heat treatment.

  • Patent number: 7863191
    Abstract: A first structure is formed, having a contact plug formed on the bottom of a first opening in an interlayer insulating film, a second opening formed through the interlayer insulating film to reach a semiconductor substrate, and a third opening formed through the interlayer insulating film to reach a polymetal gate electrode. A cobalt layer is deposited on the surface of the structure, and thermally treated to form a cobalt silicide layer on the surface of the contact plug and on the bottom face of the second opening. The structure is then treated to remove the cobalt, in the state in which the cobalt silicide layer is formed, with the use of a chemical solution capable of dissolving cobalt but not the polymetal.

  • Patent number: 7446042
    Abstract: A method for forming nickel silicide includes degassing a semiconductor substrate that includes a silicon surface. After the degassing operation, the substrate is cooled prior to a metal deposition process, during a metal deposition process, or both. The cooling suppresses the temperature of the substrate to a temperature less than the temperature required for the formation of nickel silicide. Nickel diffusion is minimized during the deposition process. After deposition, an annealing process is used to urge the formation of a uniform silicide film. In various embodiments, the metal film may include a binary phase alloy containing nickel and a further element.

    Abstract: The objects of the present invention are to form MEMS structures of which stress is controlled while maintaining the performance of high-performance LSI, to integrate MEMS Structures and LSI on a single chip, to electrically and chemically protect the MEMS structure and to reduce the stress of the whole movable part of the MEMS structure. To achieve the above objects, a silicide film formable at a low temperature is used for the MEMS structure. The temperature at the silicide film deposition T1 is selected optionally with reference the heat treatment temperature T2 and the pseudo-crystallization temperature T3. T2, the temperature of manufacturing process after the silicide film deposition, is determined does not cause the degradation of the characteristics of the high-performance LSI indispensable. Thus, the residual stress of the MEMS structures may be controlled.
