Definitions
- the present invention relates to a technique for producing polycrystalline silicon, and more particularly to arrangement of a raw material gas supply nozzle and a silicon core wire fixing electrode on a bottom plate of a reaction furnace for producing polycrystalline silicon by the Siemens method.
- Polycrystalline silicon is used as a raw material for a single crystal silicon substrate for manufacturing semiconductor devices and a substrate for manufacturing solar cells.
- a Siemens method is known as a method for producing polycrystalline silicon.
- the Siemens method is a method in which a raw material gas containing chlorosilane is brought into contact with a heated silicon core wire, and thereby polycrystalline silicon is vapor-phase grown on the surface of the silicon core wire by a CVD method to obtain a silicon rod.
- a polycrystalline silicon rod used as a raw material for producing a single crystal rod by the floating zone method (FZ method) is required to have a particularly good shape. Specifically, it is required that the polycrystalline silicon rod has a small warp and a shape with a high roundness of the cross-sectional shape.

The temperature becomes ⁇ 600 ° C. *
- the raw material gas ejected from the gas supply nozzle has a higher flow rate, lower temperature, and higher chlorosilane concentration than the circulating reaction gas in the furnace.

It becomes difficult to maintain the environment of the surface of the crystalline silicon rod in a uniform and stable state. Under such conditions, the polycrystalline silicon rod tends to have a large warp and a low cross-sectional roundness.

In this way, the gas supply nozzle is arranged to deposit polycrystalline silicon.

Polycrystalline silicon is deposited.

- the gas supply nozzle is arranged inside the virtual concentric circle A
- the virtual concentric circle Since the difference between the radius b of B and the radius a of the imaginary concentric circle A is designed to be 20 cm or more and 50 cm or less, the polycrystalline silicon rod is arranged in the circulating flow portion after the gas is sufficiently mixed.

It is.

- the difference (ba) in the radius between the virtual concentric circle B and the virtual concentric circle A which is an index of the degree of approach between the source gas nozzle 9 and the electrode pair 10, within an appropriate range.
- the appropriate radius difference depends on the shape of the gas supply nozzle 9 and the like, but when a commonly used nozzle is used, the value of (ba) is preferably 20 cm or more. From the viewpoint of effectively using the space in the reactor, the value of (ba) is preferably 50 cm or less.
- FIG. 4 is a diagram for explaining an outline of the flow of the reaction gas in the bell jar 1 ejected from the gas supply nozzle 9 arranged so as to satisfy the above relationship.
- FIG. 4 only one gas supply nozzle 9 is provided, and an outline of the gas flow when the source gas is supplied from the gas supply nozzle 9 at 150 m / second or more is shown.
- the raw material gas having a high flow velocity ejected from the gas supply nozzle 9 arranged in the above-described manner rises while accompanying the surrounding reaction gas, collides with the upper inner wall of the bell jar 1 and moves downward.
- the flow is changed to become a circulating flow and descends along the inner wall of the bell jar, and a part of the descending gas flow rises again in the reaction space together with the raw material gas ejected from the gas supply nozzle 9 to react.
- the ascending airflow region and the descending airflow region become clear throughout the furnace, and a smooth circulation flow is formed.
- the gas supply nozzle 9 is arranged so that the raw material gas ejected from the gas supply nozzle 9 does not directly hit the surface of the polycrystalline silicon 13 deposited on the silicon core wire 12. .
- the source gas that has risen to the top of the bell jar 1 hits the ceiling and spreads, but when mixed with the reaction gas circulating in the surrounding furnace on the way, the mixed gas becomes a substantially uniform temperature. It goes down to the bottom of the reactor. And it goes around to the installation area
- Such a gas flow is the same even when a plurality of gas supply nozzles 9 are provided.
- the electrode pair 10 is arranged inside the virtual concentric circle C and outside the virtual concentric circle B
- the gas supply nozzle is arranged inside the virtual concentric circle A
- the radius b of the virtual concentric circle B and the radius of the virtual concentric circle A In the polycrystalline silicon manufacturing apparatus of the present invention designed so that the difference of a is 20 cm or more and 50 cm or less, the flow of the reaction gas in the reaction furnace during the reaction is projected onto the bottom plate 5 from above the bell jar and observed.
- an updraft is generated inside the virtual concentric circle A
- an updraft is generated inside the virtual concentric circle C
- a downflow is generated outside the virtual concentric circle C on average.
- the polycrystalline silicon rod 13 Since the polycrystalline silicon rod 13 is disposed in the circulating portion after the gas is sufficiently mixed, the surface of the polycrystalline silicon rod such as the reaction gas temperature, the reaction gas concentration, and the reaction gas flow velocity is not affected. The environment can be maintained in a uniform and stable state.
- the flow velocity of the raw material gas from the gas supply nozzle 9 is set to 150 m / second or more.
- the polycrystalline silicon manufacturing apparatus having such a configuration is used, even if a large amount of source gas is supplied into the furnace, the flow state of the reaction gas circulating in the furnace is hardly disturbed, and the environment of the surface of the polycrystalline silicon rod is reduced. It becomes easy to maintain a uniform and stable state, and it is possible to suppress warpage of the polycrystalline silicon rod and a decrease in the roundness of the cross section.
- Tables 1 and 2 summarize the evaluation results such as the growth conditions of the polycrystalline silicon rod and the shape of the obtained polycrystalline silicon rod.
- the values shown in Table 2 were measured for all the polycrystalline silicon rods except for those in which the effective length (1.8 m) could not be secured due to the occurrence of cracking or collapse during the reaction for each arrangement relationship. This is the value obtained for the worst shape among the results.
- Example 2 in which the radius difference between the virtual concentric circles A and B is in the range of 20 to 50 cm and that in Comparative Example 1 that is not in the range, the radius difference affects the shape of the polycrystalline silicon rod. I can confirm that. This is because when the difference in radius is not within the above range, the source gas ejected from the gas supply nozzle directly hits the surface of the polycrystalline silicon rod, so that the reaction temperature of the portion decreases and the growth of polycrystalline silicon is suppressed. As a result, the shape of the polycrystalline silicon rod is deteriorated.
- 6 to 8 are conceptual diagrams for explaining the above-described warp ( ⁇ ), roundness (f / e), and taper (g / h).
- the polycrystalline silicon production apparatus of the present invention By using the polycrystalline silicon production apparatus of the present invention, even if a large amount of source gas is supplied into the furnace, the state of the flow of the reaction gas circulating in the furnace is hardly disturbed, and the environment of the polycrystalline silicon rod surface is uniform. It becomes easy to maintain a stable state, and it is possible to suppress warpage of the polycrystalline silicon rod and a decrease in the roundness of the cross section.
