    摘要: In a CVD processing system for depositing a blanket tungsten film, a distinct shadow is formed without causing any micro-peeling when the substrate fixture is separated from the substrate so as to prevent any blanket tungsten from being deposited on SiO.sub.2, thus reducing the occurrence of fine dust particles. A CVD processing system for depositing a blanket tungsten film, includes a susceptor (4); a ring chuck (9) for affixing the peripheral portion of a substrate (3) on the susceptor; reactive gas supply mechanisms (17, 18 and 19) for supplying reactive gas; and an exhaust mechanism (2) for exhausting unreacted gas and the like, wherein: the ring chuck has at least three point contact members (10) in contact with the peripheral portion of the substrate; the point contact members are provided at positions outside the inner periphery of the ring chuck; a gap (11) is formed at the point contact members between the ring chuck and the substrate; and purge gas supply mechanisms (20 and 21) are provided to blow off purge gas through the gap in order to prevent reactive gas from entering the gap (11). A ratio of the size of the gap to the flow rate of purge gas is set to such an optimum value as to satisfy a condition in which the position of the peripheral portion of the thin film coincides with the position of the inner periphery of the ring chuck.

The method includes depositing a metallic layer containing a reactive metal in an interconnect opening formed within a dielectric material containing a dielectric reactant element, thermally reacting at least a portion of the metallic layer with at least a portion of the dielectric material to form a diffusion barrier primarily containing a compound of the reactive metal from the metallic layer and the dielectric reactant element from the dielectric material, and filling the interconnect opening with Cu metal, where the diffusion barrier surrounds the Cu metal within the opening. The reactive metal can be Co, Ru, Mo, W, or Ir, or a combination thereof. The interconnect opening can be a trench, a via, or a dual damascene opening.

    摘要: An electrostatic chuck device provided with a dielectric plate with a surface embossed to give it a plurality of projections, an electrode, and an external power source, wherein substrate supporting surfaces of the plurality of projections are covered by conductor wiring and the conductor wiring electrically connects the substrate supporting surfaces of the plurality of projections. At the time of substrate processing, when the embossed projections contact the back of the substrate, the back of the substrate and the conductor wiring is made the same in potential due to the migration of the charges, the generation of force between the back of the substrate and the conductor wiring being in contact with the same is prevented, and a rubbing state between the two is prevented. Due to this, the electrostatic chuck device reduces the generation of particles, easily and stably removes and conveys substrates, and realizes a high yield and system operating rate.
