  • Patent number: 6852626
    Abstract: In the film deposition method of the present invention, an organometallic fluid, which has an organic metal such as a copper diketonate as its main component, and which precipitates film deposition material through a pyrolytic decomposed reaction, is first prepared; and the organometallic fluid is then applied onto a semiconductor wafer at a certain temperature within the non-reactive range of the organic metal. Afterwards, the wafer is heated to a predetermined temperature, the organic metal within the organometallic fluid that is applied onto the wafer is pyrolytically decomposed, and film is formed on the wafer. With this method, since application is performed at a temperature within the non-reactive range of the organic metal, deposition of the film does not occur, allowing uniform and homogenous application to be performed. Also, since pyrolytic decomposition is performed separately in a later process, a stable reaction may be assured, so that a film of uniform thickness and quality may be deposited.

  • Patent number: 6576567
    Abstract: In a film deposition method of depositing a film by adhering an organometallic fluid onto a to-be-processed body such as a semiconductor wafer and causing a pyrolytic decomposition reaction to occur, an organic solvent such as heptadecane is first applied onto the wafer. At this time, since heptadecane has favorable wettability to the wafer, it efficiently permeates over the entire wafer and flows into holes and trenches without an occurrence of bubbles. Next, an organic metal such as a fluid mainly containing, for example, (hfac)Cu+1(tmvs) is applied onto wafer W. At this time, since the heptadecane that is first applied is a solvent for the organic metal, the organometallic fluid is highly adaptive to heptadecane, it efficiently permeates over the entire wafer W, and evenly flows into holes etc. This allows filling-in to be performed without the development of vacancies.

  • Patent number: 6511538
    Abstract: When performing film deposition on the surface of a wafer, a turntable supporting the wafer is first rotated. Next, a fluid containing an organic metal is applied onto the wafer via the tip of a nozzle. At the same time, an ultrasound wave is generated by an ultrasound wave generating device, and the turntable is vibrated. Thus the vibrations from the turntable are applied to the wafer, these wafer vibrations allow the fluid containing an organic metal to thoroughly permeate into the detailed patterning of the wafer surface, and said fluid covers its entirety. As a result, film deposition with excellent filling-in characteristics becomes possible.
