    摘要: Methods for plating metal over features of a semiconductor wafer and devices that can be formed by these methods are disclosed. One such method includes forming a barrier layer over the substrate using electroless plating and forming a copper layer over the barrier layer. In some implementations, the semiconductor wafer is a GaAs wafer. Alternatively or additionally, the feature over which metal is plated can be a through-wafer via. In some implementations, a seed layer over the barrier layer can be formed using electroless plating.

    摘要: A method and system to form a refractory metal layer over a substrate includes introduction of a reductant, such as PH3 or B2H6, followed by introduction of a tungsten containing compound, such as WF6, to form a tungsten layer. It is believed that the reductant reduces the fluorine content of the tungsten layer while improving the step coverage and resistivity of the tungsten layer. It is believed that the improved characteristics of the tungsten film are attributable to the chemical affinity between the reductants and the tungsten containing compound. The chemical affinity provides better surface mobility of the adsorbed chemical species and better reduction of WF6 at the nucleation stage of the tungsten layer. The method can further include sequentially introducing a reductant, such as PH3 or B2H6, and a tungsten containing compound to deposit a tungsten layer. The formed tungsten layer can be used as a nucleation layer followed by bulk deposition of a tungsten layer utilizing standard CVD techniques. Alternatively, the formed tungsten layer can be used to fill an aperture.

    摘要: The present invention provides a method of improving the adhesion of a copper layer to a barrier layer on a substrate. After deposition of a barrier layer, such as TiN, an amorphous silicon layer is deposited by striking a plasma over the substrate using a silicon source gas, such as silane, and an inert gas, such as argon (Ar). A Cu layer is deposited on the amorphous silicon. In another aspect of the invention, a TiSiN layer is deposited using a silicon source gas, such as silane, and a titanium source gas, such as TDMAT, during the deposition of the TiN barrier layer.

    摘要: Thin films are formed by formed by atomic layer deposition, whereby the composition of the film can be varied from monolayer to monolayer during cycles (301) or (450, 455, 460, 470) including alternating pulses of self-limiting chemistries. In the illustrated embodiments, varying amounts of impurity sources (306 or 460) are introduced during the cyclical process. A graded gate dielectric (72) is thereby provided, even for extremely thin layers. The gate dielectric (72) as thin as 2 nm can be varied from pure silicon oxide to oxynitride to silicon nitride. Similarly, the gate dielectric (72) can be varied from aluminum oxide to mixtures of aluminum oxide and a higher dielectric material (e.g., ZrO2) to pure high k material and back to aluminum oxide. In another embodiment, metal nitride (432) (e.g., WN) is first formed as a barrier for lining dual damascene trenches and vias. During the alternating deposition process, copper can be introduced, e.g., in separate pulses, and the copper source pulses (460) can gradually increase in frequency, forming a graded transition region (434), until pure copper (436) is formed at the upper surface. Advantageously, graded compositions in these and a variety of other contexts help to avoid such problems as etch rate control, electromigration and non-ohmic electrical contact that can occur at sharp material interfaces.
