- the present disclosure provides a technique capable of selectively forming a high-density film on a convex portion.
- the film forming method is a substrate having a convex portion on the surface, and the convex portion is a step of preparing a substrate having a side surface and an upper surface, and a film is deposited on a region including the side surface and the upper surface.
- a high-density film can be selectively formed on a convex portion.

Schematic cross-sectional view showing an example of a film forming apparatus that implements the film forming method of the embodiment.
- a substrate 100 having a convex portion 110 on the surface is prepared (preparation step S11).
- the substrate 100 may be a semiconductor wafer such as a silicon wafer.
- the protrusion 110 has a side surface 111 and an upper surface 112.
- the convex portion 110 may be, for example, a convex portion of a trench.
- the film 120 is deposited in the region including the side surface 111 and the upper surface 112 of the convex portion 110 of the substrate 100 prepared in the preparation step S11 (deposition step S12).
- the deposition step S12 it is preferable to deposit the film 120 thicker on the upper surface 112 than on the side surface 111 of the convex portion 110. This facilitates the removal of the low-density film 121 in the etching step S14 described later.
- the film is supplied in a rate-determining state by chemical vapor deposition (CVD) or atomic layer deposition (ALD).
- a method of depositing 120 can be suitably used.
- the rate-determining state of supply means a region in which the flow rate of the raw material gas supplied into the processing container is very small, and the film formation rate is mainly controlled by the supply amount of the raw material gas.
- the supply rate-determining state can be realized by reducing the supply amount of the raw material gas and raising the processing temperature.
- the membrane 120 is, for example, a membrane that becomes denser when exposed to plasma.
- the film 120 include, but are not limited to, an oxide film containing silicon (Si) or a metal, a nitride film, and a carbide film.
- the film 120 include TiN, TiO 2 , Al 2 O 3 , HfO, ZrO, SnO, NbO, MoO, VO, WO, SiO 2 , SiN, SiC, SiCN, SiOC, and SiOCN.
- the raw material gas is selected according to the type of the film 120 to be deposited. For example, when a Si oxide film is deposited, the raw material gas contains a Si-containing gas and an oxidizing gas. For example, when depositing a Si nitride film, the raw material gas contains a Si-containing gas and a nitride gas. For example, when depositing a Si carbide film, the raw material gas contains a Si-containing gas and a carbide gas.

- the film 120 is exposed to plasma to increase the density of the film 120 deposited on the upper surface 112 rather than the side surface 111 of the convex portion 110 (high density step S13). Since the ions contained in the plasma enter the surface of the substrate 100 and the upper surface 112 of the convex portion 110 with directivity in a direction perpendicular to the surface, the upper surface 112 of the convex portion 110 is selectively modified to increase the density. As a result, the low-density film 121 that has not been densified remains on the side surface 111 of the convex portion 110, and the high-density film 122 that has been densified is formed on the upper surface 112 of the convex portion 110.

- the rare gas include He gas and Ar gas.
- the etching conditions are selected so as to be, for example, isotropic etching.
- the etching agent may be an etching gas or an etching solution. In the case of dry etching using an etching gas as an etching agent, etching may be performed using plasma or etching using no plasma.
- etching without plasma is preferable from the viewpoint that the low-density film 121 deposited on the side surface 111 of the convex portion 110 can be easily removed selectively.
- the etching gas include Cl 2 , HF, ClF 3 , HCl, NF 3 , CF 4 , and C 4 F 8 .
- the etching solution includes, for example, DHF (Diluted HF), H2O 2 , HCl, APM (Ammonia hydrogen Peroxide Mixture), SPM (Sulfuric hydrogen Peroxide Mixture), HPM (Hydrochloric). Hydrogen Peroxide Mixture), H 3 PO 4 .
- the process returns to the deposition step S12, and if the number of repetitions of the cycle has reached the set number, the process ends.
- the high-density film 122 can be selectively formed on the upper surface 112 of the convex portion 110.
- the film is deposited on the region including the side surface and the upper surface of the convex portion, and then the film is exposed to plasma to be more than the side surface.
- the film deposited on the upper surface is densified, and then an etching agent is supplied to the film to selectively leave the film on the upper surface of the convex portion. This makes it possible to selectively form a high-density film on the convex portion.
- FIG. 3 another example of the film forming method of the embodiment will be described.
- the film forming method shown in FIG. 3 is different from the film forming method shown in FIGS. 1 and 2A to 2E in that an etching step is performed after repeating a cycle including a deposition step and a densification step a plurality of times.
- an etching step is performed after repeating a cycle including a deposition step and a densification step a plurality of times.

- the deposition step S22 is the same as the above-mentioned deposition step S12.
- the densification step S23 is the same as the densification step S13 described above.
- first determination step S24 it is determined whether or not the number of repetitions of the cycle including the deposition step S22 and the densification step S23 has reached the set number of times. If the number of repetitions of the cycle has not reached the set number, the process returns to the deposition step S22, and if the number of repetitions of the cycle has reached the set number, the process proceeds to the next step.
- etching step S25 is the same as the etching step S14 described above.
- the process determines whether or not the set number of times is reached by performing the etching step S25 after repeating the cycle including the deposition step S22 and the densification step S23 a plurality of times (second determination step S26).
- the number of settings is determined, for example, according to the film thickness of the film formed on the upper surface of the convex portion. If the number of repetitions of the cycle has not reached the set number, the process returns to the deposition step S22, and if the number of repetitions of the cycle has reached the set number, the process ends. By repeating the cycle in this way, a high-density film can be selectively formed on the upper surface of the convex portion.
- the film is deposited on the region including the side surface and the upper surface of the convex portion, and then the film is exposed to plasma to form the film deposited on the upper surface rather than the side surface.
- the density is increased, and then an etching agent is supplied to the film to selectively leave the film on the upper surface of the convex portion. This makes it possible to selectively form a high-density film on the convex portion.
- the etching step S25 is performed after repeating the cycle including the deposition step S22 and the densification step S23 a plurality of times.
