Definitions
- the present invention relates to a method for producing a metal nitride film, a metal oxide film, a metal carbide film, or a composite film thereof
- a metal film such as a metal nitride film, a metal oxide film, or a metal carbide film
- a metal film such as a metal nitride film, a metal oxide film, or a metal carbide film
- Such a film can be freely changed in properties such as the hardness, resistance, or insulation properties of the film by appropriately adjusting the type of metal and atoms constituting the metal film, or a combination thereof. It is used as a protective film, transparent electrode, insulating film, hardened surface film, etc.
- HfN, ZrN, TiN group 4 metal nitrides have been used as barriers to replace TaN films.
- Norya is required to have the following six requirements in addition to being a thin film with low resistance. 1) Suppress Cu diffusion for heat treatment of about 400-500 ° C, 2) 01 for heat treatment of about 400-500, and no reaction with interlayer insulation film, 3) Cu And good adhesion to the interlayer insulation film, 4) as little solid solubility as possible with Cu, 5) as low resistance as possible (up to 300 ⁇ cm), 6) thermally It is stable.
- barrier materials such as TiN tend to have a columnar structure, and it can be inferred that the crystal grains have a columnar shape, but this crystal structure makes the Cu diffusion path straight. This is because the diffusion path becomes shorter and the diffusion of Cu spreads and becomes thermally unstable.
- Non-Patent Documents 1 and 2 the present inventor has studied the correlation between the structure of the barrier material and its characteristics, and even if the same barrier material is used, if the structure and structure of the Norya material are different, the characteristics of the barrier material The difference is clarified (see Non-Patent Documents 1 and 2). Among them, the present inventor made polycrystalline NOR, normally oriented barrier, and nanocrystal NOR, and studied the characteristics of each barrier. Then, it was clarified that the desired structure for nanocrystals or amorphous force barriers is U ⁇ .
- the highly oriented growth of the barrier was fabricated as a barrier in a state close to epitaxial growth, and the barrier of nanocrystals is generally very high in resistance because amorphous barriers have a very high resistance. It was made to avoid it.
- a chemical reaction is performed as a method of forming a metal nitride film as NORA.

- a chemical reaction such as decomposition, reduction, or substitution is caused by heat, plasma, light, or other energy to form a thin film on the substrate surface.
- a film obtained by the CVD method generally has high resistance and easily incorporates impurities because the metal element is present in the source gas as a compound rather than a simple substance.
- the film formation temperature is about 350 to 400 ° C., a film with relatively good film quality can be obtained, but the film quality is inferior to that of the reactive sputtering method described later.
- an ALD (Atomic Layer Deposition) method As a method for forming an ultrathin film by the CVD method, an ALD (Atomic Layer Deposition) method has been proposed (see Non-Patent Document 3).
- ALD Atomic Layer Deposition
- the ALD method needs to be repeated repeatedly in one cycle, and a new device dedicated to ALD film formation is required. Therefore, the equipment cost increases.
- the raw material used for the source gas is basically the same as that of the CVD method, the resistance of the formed film may be slightly lower than that of the CVD method.
- the ALD method uses the adsorption reaction on the surface to form a film, depending on the type of the underlying material, it is difficult to form the film itself, so the dependence on the underlying material must be considered. Nah ...
- the film forming temperature needs to be about 400 ° C or less in order to reduce the influence of the heat on the wiring.

- these raw materials contain carbon, the concentration of hydrocarbon groups in the film becomes high, and carbon or hydrogen is desorbed from the film by heat treatment, so that an unstable film is likely to be formed.
- Such a film has a problem in that it has a high resistance and a poor norrative property.

- a plastic substrate has advantages such as flexibility and light weight, but is weak against heat compared to a metal substrate. Therefore, it is desired to lower the film formation temperature when forming a metal nitride film, a metal oxide film, a metal carbide film and a composite film thereof on a plastic substrate. With regard to this low temperature, it is desirable that the temperature of the film to be formed be lower than the formation temperature (melting point) of the material forming the plastic substrate, up to room temperature! Many of the materials for general-purpose plastic substrates change in quality at 200 to 300 ° C.
- the reactive sputtering method requires a film forming temperature of about 300 to 400 ° C. in order to obtain a film having low resistance.
- the film formation temperature is 300 ° C. or lower
- the barrier resistance increases as the film formation temperature decreases, and increases to several hundred ⁇ cm around room temperature.
- a certain amount of thermal energy is required, so it is practically difficult to set the film forming temperature to 300 ° C or lower.
- sputtering methods including reactive sputtering methods do not have good filling characteristics in holes with a high aspect ratio from the viewpoint of making the film extremely thin. For this reason, there is a concern about the application of sputtering as a film formation method after the 65 nm node. Actually, a Ta (3nm) / TaN (lnm) / Ta (3nm) three-layer barrier using Ta barrier deposited by the sputtering method and TaN barrier by the ALD method is used. Up to about 3 nm, it seems that a continuous film can be formed even by sputtering. However, although there is a report of forming a metal film such as a three-layer barrier by sputtering, there is no report that an ultrathin metal nitride film of 3 to 5 nm can be formed by sputtering.
