20090120787 | METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE - A barrier film of a semiconductor device is formed. The present invention forms a middle layer having copper as a main component and including a predetermined quantity of diffusible metal with the addition of a reaction gas, by sputtering an alloy target having copper as a main component with the addition of a diffusible metal, while supplying a reaction gas including oxygen or nitrogen. Since contents of the diffusible metal are accurately controlled when heating the middle layer, the barrier film is certainly formed. Additionally, the reaction gas is added to the middle layer so that the reactivity of the diffusible metal becomes high; and accordingly, it is possible to form the barrier film at a heating temperature lower than the conventional art. | 05-14-2009 |

20120111722 | FILM-FORMING APPARATUS - There is provided a film forming apparatus for forming a coating film on a surface of an object to be processed by using a sputtering method, the film forming apparatus including: a chamber for accommodating the object and a target serving as a base material for the coating film that are placed so as to face each other; an exhaust unit for reducing the pressure inside the chamber; a magnetic field generating unit for generating a magnetic field in front of the sputtering surface of the target; a direct current power supply for applying a negative direct current voltage to the target; a gas introducing unit for introducing a sputtering gas into the chamber; and a unit for preventing the entering of sputtered particles onto the object until the plasma generated between the target and the object reaches a stable state. | 05-10-2012 |
20120118732 | FILM FORMATION APPARATUS - A film formation apparatus includes: a chamber having a side wall and an inner space in which both a body to be processed and a target are disposed a first magnetic field generation section generating a magnetic field in the inner space a second magnetic field generation section disposed at a position close to the target, the second magnetic field generation section generating a magnetic field so as to allow perpendicular magnetic lines of force thereof to pass through a position adjacent to the target; and a third magnetic field generation section disposed at a position close to the body to be processed, the third magnetic field generation section generating a magnetic field so as to induce the magnetic lines of force to the side wall of the chamber. | 05-17-2012 |
20120121818 | COATING SURFACE PROCESSING METHOD AND COATING SURFACE PROCESSING APPARATUS - A coating surface processing method includes forming a coating on the entire surface of a base body that has fine holes or fine grooves formed on the to-be-filmed surface, including the inner wall surfaces and the inner bottom surfaces of the holes or the grooves, and flattening the coating formed on the inner wall surfaces of the holes or the grooves by carrying out a plasma processing on the surface of the coating. | 05-17-2012 |
20130239993 | FILM-FORMING APPARATUS AND METHOD FOR CLEANING FILM-FORMING APPARATUS - A film-forming apparatus includes a heat generator exposed to a film-forming gas drawn into a chamber to generate film formation species. A film-forming gas supply system supplies the film-forming gas into the chamber. A control unit sets the heat generator in a non-heated state during a cleaning process that discharges a film formation residue from the chamber. A cleaning gas supplying system supplies a cleaning gas including ClF3 into the chamber. A temperature adjustment unit adjusts the chamber to a target temperature from 100° C. or higher to 200° C. or less in the cleaning process. A discharge system discharges a reaction product produced by a reaction between the film formation residue and the cleaning gas from the chamber. | 09-19-2013 |
