摘要:
A deposition method for supplying process gases into an evacuated processing vessel to deposit a metal tungsten film on the surface of an object to be processed. The processing gases include tungsten hexafluoride gas, hydrogen gas, and a reducing gas which has a richer reducing property than that of the hydrogen gas, the amount of the reducing gas being smaller than that of the hydrogen gas. Thus, it is possible to form a metal tungsten film without increasing stress in the film so much even in a low temperature region of about 400° C. and without decreasing a deposition rate so much.

A vacuum process system having a vacuum process container. Located inside the vacuum process container is a supporting table for supporting thereon an object to be processed, a presser member for pressing the top surface of the peripheral portion of the object onto the supporting table, and a shower head facing the supporting table. The shower head has a large number of gas nozzles in the bottom face thereof. The bottom face of the shower head has a facing portion positioned substantially directly above the inner peripheral edge of the presser member and a non-facing portion. The facing portion has nozzles with larger diameters than the non-facing portion or a higher density of nozzles than the non-facing portion.

A processing apparatus includes a processing chamber, a support mechanism provided in the processing chamber to support a wafer having an underlying film formed on a major surface and adjacent side face, and a supply member provided at the processing chamber and spaced from the support mechanism, to supply an incoming gas into the processing chamber. A gas carrying mechanism is provided for selectively sending a film forming gas and etching gas to the gas supply member. A main film is formed on a portion of an underlying film formed on the wafer supported on the support mechanism, by using the film forming gas supplied from the gas supply member. A portion of the underlying film, which is exposed, not covered with the main film, is etched away by the etching gas supplied from the gas supplied member.

A wafer processing apparatus (14) has a wafer processing vessel (16). A wafer is mounted on a susceptor (22) included in the wafer processing apparatus. Process gases are supplied to the wafer through a shower head (74) disposed in an upper region within the processing vessel to carry out a predetermined process for processing the wafer. The surfaces of aluminum members (16, 74) employed in the wafer processing apparatus are subjected to an organic mechanical chemical polishing process, a blasting process and an aluminum oxide film forming process in that order. It is difficult for unnecessary films to adhere to the thus treated surfaces and it is difficult for unnecessary films deposited on the thus treated surfaces to come off the surfaces. Consequently, intervals between cleaning operations can be extended and production of particles can be suppressed.

摘要:
A functionally gradient inorganic resist that changes in its state by heat, having a main surface irradiated with laser beams and a rear surface opposed to the main surface; the functionally gradient inorganic resist including a single layer resist, wherein at least a composition of the single layer resist is continuously varied from the main surface side to the rear surface side, and anisotropy of an area in which a temperature reaches a fixed temperature when being irradiated with laser beams locally, is continuously increased from the main surface side to the rear surface side in the single layer resist.
摘要:
A showerhead for use in a process chamber for performing a predetermined process on an object, designed to apply a prescribed gas in the process chamber. The showerhead comprises a main body, a cover, and a support. The main body has a an internal space into which the gas to be supplied into the process chamber is introduced and an opening which opens to the process chamber. The cover closes the opening of the main body and has a plurality of gas-applying holes for applying the gas from the main body. The support supports the cover to the main body and provides a predetermined clearance between the cover and the main body.
