Abstract

A method of manufacturing a semiconductor device includes forming a film on a substrate by overlapping the following during at least a certain period: (a) supplying a first source to the substrate, the first source including at least one of an inorganic source containing a specific element and a halogen element and an organic source containing the specific element and the halogen element; (b) supplying a second source to the substrate, the second source including at least one of amine, organic hydrazine, and hydrogen nitride; and (c) supplying a third source to the substrate, the third source including at least one of amine, organic hydrazine, hydrogen nitride, and organic borane.

Claims (35)

1. A method of manufacturing a semiconductor device comprising forming a film on a substrate by overlapping the following during at least a certain period:

(a) supplying a first source to the substrate, the first source including at least one of an inorganic source containing a specific element and a halogen element and an organic source containing the specific element and the halogen element;

(b) supplying a second source to the substrate, the second source including at least one of amine, organic hydrazine, and hydrogen nitride; and

(c) supplying a third source to the substrate, the third source including at least one of amine, organic hydrazine, hydrogen nitride, and organic borane,

wherein the second source includes amine, and the third source includes hydrogen nitride, and the method further comprising supplying a fourth source including organic borane to the substrate.

2. A method of manufacturing a semiconductor device comprising forming a film on a substrate by overlapping the following during at least a certain period:

(a) supplying a first source to the substrate, the first source including at least one of an inorganic source containing a specific element and a halogen element and an organic source containing the specific element and the halogen element;

(b) supplying a second source to the substrate, the second source including at least one of amine, organic hydrazine, and hydrogen nitride; and

(c) supplying a third source to the substrate, the third source including at least one of amine, organic hydrazine, hydrogen nitride, and organic borane,

wherein the second source includes first amine, and the third source includes second amine having a different chemical structure from that of the first amine.

3. The method according to claim 2 , wherein a degree of substitution of one of the first amine and the second amine is smaller than a degree of substitution of the other.

4. The method according to claim 2 , further comprising supplying a fourth source including hydrogen nitride to the substrate.

5. The method according to claim 2 , further comprising supplying a fourth source including organic borane to the substrate.

6. A method of manufacturing a semiconductor device comprising forming a film on a substrate by overlapping the following during at least a certain period:

(a) supplying a first source to the substrate, the first source including at least one of an inorganic source containing a specific element and a halogen element and an organic source containing the specific element and the halogen element;

(b) supplying a second source to the substrate, the second source including at least one of amine, organic hydrazine, and hydrogen nitride; and

(c) supplying a third source to the substrate, the third source including at least one of amine, organic hydrazine, hydrogen nitride, and organic borane,

wherein the second source includes amine or hydrogen nitride, and the third source includes organic borane.

7. A method of manufacturing a semiconductor device comprising forming a film on a substrate by overlapping the following during at least a certain period:

(a) supplying a first source to the substrate, the first source including at least one of an inorganic source containing a specific element and a halogen element and an organic source containing the specific element and the halogen element;

(b) supplying a second source to the substrate, the second source including at least one of amine, organic hydrazine, and hydrogen nitride; and

(c) supplying a third source to the substrate, the third source including at least one of amine, organic hydrazine, hydrogen nitride, and organic borane,

wherein the first source contains a chemical bond of the specific element and nitrogen, the first source contains a chemical bond of the specific element and oxygen, or the first source includes both of the inorganic source and the organic source.

8. A substrate processing apparatus comprising:

a process chamber configured to accommodate a substrate;

a first supply system configured to supply a first source to the substrate in the process chamber, the first source including at least one of an inorganic source containing a specific element and a halogen element and an organic source containing the specific element and the halogen element;

a second supply system configured to supply a second source to the substrate in the process chamber, the second source including at least one of amine, organic hydrazine, and hydrogen nitride;

a third supply system configured to supply a third source to the substrate in the process chamber, the third source including at least one of amine, organic hydrazine, hydrogen nitride, and organic borane; and

a controller configured to control the first supply system, the second supply system, and the third system such that a film is formed on the substrate by overlapping the following during at least a certain period: (a) supplying the first source to the substrate in the process chamber, (b) supplying the second source to the substrate in the process chamber, and (c) supplying the third source to the substrate in the process chamber,

wherein the second source includes first amine, and the third source includes second amine having a different chemical structure from that of the first amine.

9. A non-transitory computer-readable recording medium storing a program that causes a substrate processing apparatus to perform a process, in a process chamber of the substrate processing apparatus by a computer, the process comprising forming a film on a substrate by overlapping the following during at least a certain period:
