    摘要: The semiconductor device has a multilayer structure wherein a substantially pure silicon dioxide film containing substantially no fluorine atom and a silicon dioxide film containing fluorine atoms are sequentially laminated on a substrate. Etching rate of a silicon dioxide film depends on a fluorine concentration in the film, so that a suitable etch selectivity of the silicon dioxide film containing fluorine atoms from the substantially pure silicon dioxide film can be obtained to form an oxide trench used for a trench interconnection and a via-hole used for a via-plug. The oxide film containing fluorine atoms has as good a quality as the silicon dioxide film not containing impurities has, thereby obtaining a superior characteristic of the semiconductor device. Addition of fluorine atoms reduces a specific permittivity to thereby obtain a higher speed.

    摘要: In the plating solution in the plating bath, a wafer and an anode electrode are opposed to each other, between which is interposed a disk-shaped auxiliary electrode having a diameter smaller than that of the wafer. This auxiliary electrode has a plurality of holes formed therein. Through these holes, the plating solution is uniformly supplied to between the wafer and the anode electrode. The auxiliary electrode is supplied with the same positive potential as that of the anode electrode. This forms electric lines of force directed from the auxiliary electrode and the anode electrode to the wafer. The closer provision of the anode electrode (the auxiliary electrode) compensates a drop in current density on the wafer resulting from the potential drop at the portion far from cathode terminals.

    摘要: The flexibility of a wiring design is improved by preventing any erosion from happening upon forming a buried wiring. An interlayer insulating film is formed on a silicon substrate, and then trenches are formed in the interlayer insulating film. Thereafter, the barrier layer is deposited on side surfaces and a bottom surface in the trenches and on an entire area on the interlayer insulating film, and a copper seed layer is formed over an entire area on the barrier layer. Fountain plating is performed using the copper seed layer as an electrode to deposit the copper plated layer on the trenches and on a peripheral area of the same the copper plated layer buries the trenches and has a protruded configuration. Thereafter, the surface of the copper plated layer is polished with a CMP method until the interlayer insulating film is exposed to form a buried wiring.
