  • Publication number: 20100013046
    Abstract: In order to improve the reliability of a semiconductor device having a fuse formed by a Damascene technique, a barrier insulating film and an inter-layer insulating film are deposited over a fourth-layer wiring and a fuse. The barrier insulating film is an insulating film for preventing the diffusion of Cu and composed of a SiCN film deposited by plasma CVD like the underlying barrier insulating film. The thickness of the barrier insulating film covering the fuse is larger than the thickness of the underlying barrier insulating film so as to improve the moisture resistance of the fuse.

  • Publication number: 20090242511
    Abstract: A seasoning method for a film-forming apparatus configured to form a silicon nitride film on a substrate placed in a process chamber. The method is conducted for reducing particles in the apparatus. The method comprises executing the plasma cleaning of the process chamber to remove a film deposited on the inner wall thereof (step S1), subsequently depositing an amorphous silicon film (step S2), depositing thereon a silicon nitride film in which the nitrogen content gradually increases in the thickness direction (step S3), and keeping the inside of the process chamber being filled with a rare-gas plasma until film formation on the substrate is initiated (step S4).

  • Publication number: 20090176380
    Abstract: Provided are a plasma treatment method and a plasma treatment device capable of forming a silicon nitride film having high compressive stress. In the plasma treatment method for depositing the silicon nitride film on a process target substrate by use of plasma of raw material gas containing silicon and hydrogen and of nitrogen gas, ion energy for disconnecting nitrogen-hydrogen bonding representing a state of bonding between the hydrogen in the raw material gas and the nitrogen gas is applied to the process target substrate so as to reduce an amount of nitrogen-hydrogen bonding contained in the silicon nitride film.

  • Publication number: 20070246799
    Abstract: A first opening portion for via hole opening is formed above an electrode groove and a second opening portion for via hole opening for connecting with wiring layer is formed on interlayer insulation film at a position corresponding to the top portion of wiring layer provided out of a capacitor formation area. At this time, the diameter of the opening of the first opening portion is set larger than the second opening portion. If the diameter of the second opening portion is 0.36 ?m, the diameter of the opening of the first opening portion is set to 0.38 ?m.

  • Publication number: 20070107843
    Abstract: In a film-forming apparatus for forming a thin film (15) on a substrate (6) by supplying a gas (13) through a gas nozzle (14) into a vacuum chamber (1) and transforming the gas (13) into a plasma by applying a current to a high-frequency antenna (7), a ceramic inner cylinder (20) is arranged so as to contact with the vacuum chamber (1) at only a small area of the cylinder for preventing adhesion of the film-forming component onto the inner wall of the vacuum chamber (1). In this film-forming apparatus, it is possible to suppress generation of particles and to reduce the workload of the cleaning process.
