摘要:
A semiconductor device with a contact structure includes a silicon substrate, a diffusion region formed in a surface of the silicon substrate, a silicide film of a high melting point metal deposited on the diffusion region, an insulating film formed on the silicon substrate, a contact hole formed in the insulating film such that the silicide film is exposed at a bottom of the contact hole, an anti-diffusion film formed on at least the exposed surface of the silicide film at the bottom of the contact film, a plug formed in the contact hole by selective Al-CVD, and a metal wiring formed on the insulating film. The metal wiring is electrically connected to the diffusion region by the plug, the anti-diffusion film and the silicide film. The anti-diffusion film is formed by nitriding the surface of the silicide film such that only the grain boundaries of the grains of the silicide film are nitrided.

Locking claw engages a recording medium to be transferred, and a determination is made as to which of a plurality of predetermined points a current position of the locking member corresponds to. Current position of the recording medium can be determined indirectly on the basis of the thus-determined predetermined point corresponding to the current position of the locking member. If any recording medium is not properly settled in a predetermined rest position at power-ON, then the recording medium is automatically transferred to be settled in the predetermined rest position. Simplified detection of the position of the locking claw is made in absolute or quasi-absolute form, by a picker position detector unit that is provided in association with a rotating drive shaft of the locking member and employs a simply-constructed mechanism capable of generating detection pulses responsive to predetermined rotational angles of two shafts rotating at different rates. Each of the plurality of predetermined points defined for the locking claw can be identified in absolute or quasi-absolute form on the basis of a combination of patterns of the thus-generated pulses. Thus, in feed transfer of a recording medium, such as a DVD medium, the position of the medium can be detected in a simplified manner and can be automatically controlled to be properly settled in the predetermined position upon power-ON.

A high-pressure processing apparatus is used for performing a film formation process on a target object, while using a process fluid containing a high-pressure fluid and a film formation source material. The apparatus includes a pressure tight container defining a process field for accommodating the target object, and configured to withstand a pressure applied from the high-pressure fluid. The pressure tight container is made of a first material. A support member is disposed inside the pressure tight container to support the target object. A fluid supply system is configured to supply the process fluid onto the target object. A thermally shielding layer is disposed to cover a surface of the pressure tight container defining the process field. The thermally shielding layer is made of a second material having a thermal conductivity higher than that of the first material.

A reduction process is performed at a low temperature to thereby realize a high production yield. An ion supply unit heats negative ions containing hydride ions to a predetermined temperature. The ion supply unit applies an electric field to a negative ion source with a predetermined intensity, so that the hydride ions are extracted from the negative ion source. Further, the ion supply unit supplies the hydride ions extracted into a processing chamber by a nonreactive gas of a carrier gas to thereby reduce an oxide film formed on a surface of a metallic film on a semiconductor wafer disposed inside the processing chamber.

Both of a first insulating film and a second insulating film are formed by a spin coating method. Accordingly, the formation of the first insulating film and the second insulating film can be performed in the same SOD processing system. Moreover, the aforesaid formation of both of the first insulating film and the second insulating film by the spin coating method can provide favorable low dielectric constant properties and good adhesion of the first insulating film and the second insulating film.

A method for forming a multilevel interconnection of a semiconductor device of the present invention includes the steps of forming a first wiring layer by depositing a metallic film containing aluminum on an insulating film of a substrate and patterning the metallic film, forming an interlayer insulating film on the entire surface of the substrate to cover the wiring layer from the upper side, forming a connection hole reaching to the first wiring layer at a predetermined position of the interlayer insulating film, selectively depositing aluminum onto an interior of the connection hole at a volume fraction of 100% or more by CVD to fill the interior of the connection hole, flattening the entire upper surface of the interlayer insulating film including the connection hole filled with aluminum by a polishing process, washing the entire surface flattened by the polishing process, and depositing the metallic film containing aluminum at a predetermined position of the upper surface of the flattened and washed interlayer insulating film and patterning the metallic film, thereby forming a second wiring layer connected to the first wiring layer through aluminum filled in the connection hole.
