    摘要: A pre-ECD surface treatment. After forming the barrier material (110) and seed layer (112), the surface of the seed layer (112) is treated with an H2 plasma to remove surface contamination (122), reduce any CuOx (123), and improve wettability. The ECD copper film (124) is then formed over the seed layer (112).

    摘要: The present invention provides a method for manufacturing a semiconductor device and a method for manufacturing an integrated circuit including the semiconductor device. The method for manufacturing the semiconductor device, among other possible steps, includes forming a polysilicon gate electrode (250) over a substrate (210) and forming source/drain regions (610) in the substrate (210) proximate the polysilicon gate electrode (250). The method further includes forming a protective layer (710) over the source/drain regions (610) and the polysilicon gate electrode (250), then removing the protective layer (710) from over a top surface of the polysilicon gate electrode (250) while leaving the protective layer (710) over the source/drain regions (250). After the protective layer (710) has been removed from over the top surface of the polysilicon gate electrode (250), the polysilicon gate electrode (250) is silicided to form a silicided gate electrode (1310). The protective layer (710) is also removed from over the source/drain regions (610) and source/drain contact regions (1610) are formed.

    摘要: A method of manufacturing a semiconductor device includes the steps of providing a semiconductor substrate (102), forming a dielectric layer (104) over the semiconductor substrate (102), and etching a trench structure (106) or a via structure (106) in the dielectric layer (104) to expose a portion of a surface of the semiconductor substrate (102). The method also includes the steps of treating a surface (104a) of the dielectric layer (104) with an adhesion solution, such as a reactive plasma including hydrogen, and forming a diffusion barrier layer (110) over the dielectric layer (104). Moreover, the adhesion solution chemically interacts with the surface (104a) of the dielectric layer (104) and enhances or increases adhesion between dielectric layer (104) and diffusion barrier layer (110).

    摘要: A capping layer (118) is used during an anneal to form fully silicided NiSi gate electrodes (120). The capping layer (118) comprises a material with an affinity for boron, such as TiN. The capping layer (118) serves as a boron trap that reduces the interface boron concentration for PMOS transistors without reducing the interface arsenic concentration for NMOS transistors.

    摘要: A conducting plug/contact structure for use with integrated circuit includes a tungsten conducting plug formed in the via with a tungsten-silicon-nitride (WSiYNZ) region providing the interface between the tungsten conducting plug and the substrate (silicon) layer. The interface region is formed providing a nitrided surface layer over the exposed dielectric surfaces and the exposed substrate surface (i.e., exposed by a via in the dielectric layer) prior to the formation of tungsten/tungsten nitride layer filling the via. The structure is annealed forming a tungsten conducting plug with a tungsten-silicon-nitride interface between the conducting plug and the substrate. According to another embodiment, a tungsten nitride surface layer is formed over the nitrided surface layer prior to the formation of a tungsten layer to fill the via. According to another embodiment, a silicon surface layer is applied to the exposed surface of the dielectric layer and to the exposed surface of the substrate prior to formation of the nitrided surface layer. A layer of tungsten, tungsten/tungsten nitride, or tungsten nitride is formed to fill the via. After annealing, a tungsten conducting plug is formed with a tungsten-silicon-nitride interface region with the substrate.
