摘要:
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 method of forming a refractory metal film doped with III or V group elements. The first process gas is supplied from a first gas source through a first gas introducing member to and through a gas supply mechanism toward a substrate within a processing vessel. The second process gas is supplied from a second gas source through a second gas introducing member to and through the gas supply mechanism toward the substrate within the processing vessel. The processing vessel is purged by evacuating the processing vessel by an evacuating mechanism, while supplying the inert gas from a third source through a third gas introducing member to and through the gas supply mechanism into the processing vessel. The supplying the first process gas and the supplying the second process gas are repeated with the supplying the purging gas being carried out between supplying the first and second gases performed so that residual gas present in the processing vessel after performing the supplying of the first and second process gases is reduced to a level of 1 to 30% based on the entire capacity of the processing vessel.

A TiSiN film is used as a barrier metal layer for a semiconductor device to prevent the diffusion of Cu. The TiSiN film is formed by a plasma CVD process or a thermal CVD process. TiCl4 gas, a silicon hydride gas and NH3 gas are used as source gases for forming the TiSiN film by the thermal CVD process. TiCl4 gas, a silicon hydride gas, H2 gas and N2 gas are used as source gases for forming a TiSiN film by the plasma CVD process.

A film forming apparatus and method of the present invention include a substrate holding section for holding a plurality of substrates in a plane within a chamber, first and second process gas discharge sections provided opposite to the substrate holding section to discharge first and second process gases, a rotation mechanism for rotating the substrate holder, and a heater for heating the substrates. While the substrates are rotating as the substrate holding section rotates, the substrate holding section, first and second mono atomic layers are alternately stacked on the corresponding substrates. A compound film is therefore formed through a reaction involved under heating.

A vacuum processing apparatus includes: a vacuum processing chamber for processing a target object; a processing gas supply source for supplying a processing gas by which a process is performed to the target object in the vacuum processing chamber; a processing gas supply pipe for supplying the processing gas from the processing gas supply source into the vacuum processing chamber; and a pressure reducing valve for keeping the gas supply pipe at a lower pressure than the atmospheric pressure when the processing gas is to be supplied to the vacuum processing chamber.
摘要:
Pre-coating films are formed in a pretreatment by supplying first film-forming gases into a process chamber of a process vessel while heating the process chamber so as to form a first pre-coating film on the inner surface of the process vessel exposed to the process chamber, followed by supplying second film-forming gases into the process chamber to form a second pre-coating film on the first pre-coating film. A semiconductor wafer is loaded into the process chamber. Then, the first gases are supplied into the process chamber while heating the process chamber so as to form a first layer on the wafer, followed by supplying the second gases into the process chamber so as to form a second layer on the first layer. A silane gas is supplied into the process chamber to permit silicon material to be deposited on the surface of the second layer stacked on the first layer. Finally, the wafer having the first and second multi-film is unloaded out of the process vessel.

A heat treatment apparatus includes a treatment container having a reaction chamber, and a gas chamber a mount table provided in the treatment container for mounting thereon a wafer such that an upper surface of the wafer is exposed to the reaction chamber, and an annular clamp member provided in the reaction chamber, movable between a clamp position in which it contacts the peripheral edge of the wafer in circular line contact and a waiting position in which it is separated from the wafer. The line contact prevents leakage of the process gas from the reaction chamber through a clearance between the clamp member and the wafer.

A workpiece treating method includes a temperature rise step in which first temperature control is performed and a treatment step in which second temperature control is performed and is adapted to treat a workpiece whose emissivity of infrared rays in the temperature rise step is different from that in the treatment step. In the temperature rise step, the temperature of the workpiece is detected by a non-contact type temperature detecting means so as to perform the first temperature control. In the treatment step, the temperature of the workpiece is detected by a contact type temperature detecting means so as to perform the second temperature control.
