Definitions
- the present invention relates to a technique for forming a fluorine-added carbon film (fluorocarbon film) using plasma.
- a multilayer wiring structure is adopted as one method for achieving high integration of semiconductor devices.
- adjacent wiring layers are connected by a conductive layer, and a thin film called an interlayer insulating film is formed in a region other than the conductive layer.
- a typical example of the interlayer insulating film is a silicon oxide film, but it is required to lower the relative dielectric constant of the interlayer insulating film in order to further increase the operation speed of the device.
- a fluorine-added carbon film that can significantly lower the relative dielectric constant as compared with a silicon oxide film has been attracting attention.
- This fluorine-added carbon film is formed by a film-forming species obtained by converting a source gas composed of carbon (C) and fluorine (F) into plasma.
- Known source gases include CF gas and CF gas. Of which, by using CF gas
- Japanese Patent Application Laid-Open No. 11-162960 discloses that a CF gas having an annular structure is used as a raw material gas.
- a technique for forming a nitrogen-added carbon film is described. Specifically, a gas for generating plasma such as Ar gas is converted into plasma by electron cyclotron resonance (ECR), and the CF gas is activated by this plasma to form a fluorine-added carbon film on a semiconductor wafer (hereinafter referred to as “U”).
- ECR electron cyclotron resonance
- film properties such as peak current and thermal stability may be different.
- the present inventors consider that the film forming conditions are greatly related to the film characteristics of the fluorine-added carbon film. Specifically, the CF gas power obtained by the film formation conditions varies depending on the film formation type. We recognize that the film characteristics change greatly due to the difference. Therefore, it is considered that a fluorine-added carbon film with good film characteristics can be formed by optimizing the film forming conditions. Disclosure of the invention
- the present invention has been made under such circumstances, and by obtaining a desired film-forming species by optimizing the film-forming conditions, fluorine having excellent leak characteristics and thermal stability is obtained. It is an object of the present invention to provide a plasma film forming method and a plasma film forming apparatus capable of forming an additive carbon film. It is another object of the present invention to provide a storage medium storing a program for controlling a plasma film forming apparatus so as to perform such film formation.
- the present invention relates to a source gas of a compound composed of carbon and fluorine and having a single triple bond, one or more double bonds, or a conjugated double bond. Activated on the basis of energy, and thus obtained film seeds containing CF or CF
- the raw material gas is adjusted so that the raw material gas concentration after activation is 0.05 times or more and 0.5 times or less than the raw material gas concentration before activation.
- a plasma film forming method characterized by being activated.
- the compound having one single triple bond is octafluoropentin.
- the compound having one or more double bonds is selected from the group consisting of octafluorocyclopentene, decafluorocyclohexene, and octafluorocyclohexagen.
- the compound having a conjugated double bond is octafluoropentagen.
- the present invention is based on microwave energy based on a source gas of a compound composed of carbon and fluorine and having a single triple bond, one or more double bonds, or a conjugated double bond. ! / Further activation, and the resulting fluorine or CF-containing film-forming seeds added fluorine to the substrate surface.
- An airtight processing container provided with a mounting table on which the substrate is mounted;
- a raw material gas supply system for adjusting the flow rate of the raw material gas and supplying the raw material gas
- a source gas supply port is formed and has a facing surface facing the mounting table, and the source gas supplied from the source gas supply system is discharged from the supply port into the processing container.
- a radial line slot antenna provided facing the mounting table
- a microwave supply system for supplying power to the antenna by adjusting the power of the microwave
- the exhaust gas is activated so that the source gas concentration after activation is 0.05 times or more and 0.5 times or less than the concentration of the source gas before activation.
- a plasma film forming apparatus further comprising a system, a source gas supply system, and a controller for controlling the microwave supply system.
- the present invention is based on microwave energy based on a raw material gas of a compound composed of carbon and fluorine and having a single triple bond, one or more double bonds, or a conjugated double bond! Fluorine-added to the substrate surface by the CF or CF-containing film-forming species obtained
- An airtight processing container provided with a mounting table on which the substrate is mounted;
- a raw material gas supply system for adjusting the flow rate of the raw material gas and supplying the raw material gas
- a source gas supply member that has a facing surface that is opposed to the mounting table in which a source gas supply port is formed, and that discharges the source gas supplied from the source gas supply system into the processing container from the supply port;
- a discharge gas supply system for supplying a discharge gas by adjusting a flow rate
- a discharge gas supply member for forming a discharge gas supply port and having a facing surface facing the mounting table, and discharging discharge gas supplied from the discharge gas supply system into the processing vessel from the supply port;
- a radial line slot antenna provided facing the mounting table
- a microwave supply system for supplying power to the antenna by adjusting the power of the microwave
- the distance between the substrate surface on the mounting table and the facing surface of the source gas supply member is 70 m. m or more and 105 mm or less
- the distance between the substrate surface on the mounting table and the facing surface of the discharge gas supply member is 100 mm or more and 140 mm or less
- the exhaust system, the raw material gas supply system, and the discharge gas supply system are controlled so that the pressure in the processing container is 7.32 Pa or more and 8.65 Pa or less, and the antenna member is attached to the antenna member.
- a plasma film forming apparatus further comprising a controller for controlling the microwave supply system so that the electric power of the supplied microwave is 2000 W or more and 2300 W or less.
- the "discharge gas” is a substance gas that, unlike the raw material gas, does not generate a deposit itself even if it is converted to plasma, and corresponds to, for example, argon gas or krypton gas.
- “activate the source gas based on the microwave energy” means that the source gas itself is directly converted into plasma by the microwave energy and activated.
