  • Publication number: 20030003771
    Abstract: A plasma enhanced chemical vapor deposition (PECVD) process is provided for depositing one or more dielectric material layers on a substrate for use in interconnect structures of integrated circuits. The method comprises the steps of depositing a fluorinated amorphous carbon (a-F:C) layer on a substrate by providing a fluorine containing gas, preferably octafluorocyclobutane, and a carbon containing gas, preferably methane, in ratio of approximately 5.6, so as to deposit a a-F:C layer having an internal compressive stress of approximately 28 MPa. After deposition the film is annealed at approximately 400° C. for approximately two hours. An adhesion promoter layer of relatively hydrogen-free hydrogeneated silicon carbide is then deposited on the a-F:C layer using silane (SiH4) and methane (CH4) as the deposition gases.

  • Patent number: 6495449
    Abstract: A method has been provided for improving the adhesion of copper to a nitrided metal diffusion barrier material, such as TiN, in an integrated circuit substrate. The method provided a multilayered diffusion barrier structure, comprising a nitrided metal diffusion barrier layer and an oxy-nitrided metal layer. The formation of an oxy-nitrided metal layer, instead of an oxide layer, permits the optimization of both contact resistance and adhesion property. The oxy-nitrided metal layer is formed either by the partial incorporation of oxygen into the nitrided metal diffusion barrier or by deposition in an oxygen ambient.

  • Publication number: 20020179014
    Abstract: A replaceable shielding apparatus provides a cost effective way of shielding a portion of a workpiece during processing. The apparatus includes a replaceable shield, made of comparable weight as the workpiece for allowing replacement of the shield in the same way as the replacement of the workpiece. With this feature, the replacement of the shield is a routine process and would not interfere much with the workpiece operation. The invention further includes a shield clamp for clamping the shield onto the workpiece. In a preferred embodiment, the invention further includes a non-reactive gas inlet for creating a pressurized cavity in the vicinity of the shielded portion of the workpiece.

  • Patent number: 6488272
    Abstract: A precursor delivery system emulsifier is provided for delivery a mixture of liquid and gas precursors. Since the liquid precursor is mixed with a gas, the flow pattern of the emulsified precursor can be controlled and modified and the relatively large flow rate of the emulsified precursor prevents the line from being clogged. Further, the mixing of the liquid precursor and gas at a site outside the vaporization chamber permits the liquid precursor line to remain cool, so that even the small diameter line remains unclogged.

  • Publication number: 20020154971
    Abstract: A wafer transfer apparatus provides a rotational and translational motions using only one stationary motor drive. The apparatus includes a drive assembly and a transport arm assembly. The transport arm assembly includes a transport arm rotatably attached to a linking arm. The linking arm is fixedly attached to a sleeve, which is rotatably attached to a housing. A shaft runs axially through the sleeve, and coupled with the transport arm so that rotation of the sleeve relative to the shaft causes the movement of the transport arm assembly. A locking mechanism allows the shaft to be locked to the housing or to the sleeve. A motor fixedly attached to the housing and operational attached to the sleeve. When the shaft is locked to the sleeve, the motor rotates the sleeve and the shaft simultaneously, which effects rotation of the transfer arm relative to the housing.

  • Publication number: 20020086528
    Abstract: A method is provided for promoting adhesion of CVD copper to diffusion barrier material in integrated circuit manufacturing. The method uses a two-step CVD copper metallization process. Following deposition of a diffusion barrier layer on the IC substrate, a first layer of CVD copper is deposited on the barrier material. The first layer is preferably thin (less than 300 Å) and deposited using a precursor which yields an adherent conforming layer of copper. The suggested precursor for use in depositing the first layer of CVD copper is (hfac)Cu(1,5-Dimethylcyclooctadiene). The first layer of CVD copper serves as a “seed” layer to which a subsequently-deposited “fill” or “bulk” layer of CVD copper will readily adhere. The second copper deposition step of the two-step process is the deposit of a second layer of copper by means of CVD using another precursor, different from (hfac)Cu(1,5-Dimethylcyclooctadiene).
