Shower head, device and method for manufacturing thin films |
摘要 |
The present invention herein provides a shower head whose temperature can be controlled in consideration of the film-forming conditions selected and a thin film-manufacturing device which permits the stable and continuous formation of thin films including only a trace amount of particles while reproducing a good film thickness distribution and compositional distribution, and a high film-forming rate and which is excellent in the productivity and the mass-producing ability as well as a method for the preparation of such a film. The shower head is so designed that the shower head structure is incorporated into an upper cap of a film-forming vessel, that a heat-exchange means is disposed in the upper cap to thus control the temperature of the upper cap and to in turn allow heat-exchange to occur at the contact surface between a disk-like shower plate constituting the shower head surface and the upper cap and that the temperature of the shower head can be controlled in consideration of the film-forming conditions selected. A thin film-manufacturing device is equipped with the shower head in its film-forming vessel and a thin film is prepared using the device. |
