- FIG. 5 is a schematic sectional view showing another specific example of the semiconductor manufacturing apparatus according to the present invention.
- a ceramic support 2 is supported in a reaction vessel 1 by a ceramic cylindrical support member '3, and an inert gas supply pipe 4 is provided. And an inert gas exhaust pipe 5, and exhaust gas is simultaneously exhausted by the exhaust pump 6 while supplying the inert gas into the cylindrical support member 3.
- the electrode 8 provided on the back surface of the ceramic holder 2 for supplying power to the resistance heating element 7 and the lead wire 9 connected to the electrode 8 are housed in the cylindrical support member 3 and a part of the reaction vessel 1 From outside the system put out.
- the silicon wafer 10 as the object to be processed is held on the surface of the ceramic holder 2 as shown in FIG. 1, and the reactive gas is introduced into the reaction vessel 1 through the reactive gas supply pipe 11.
- the gas is exhausted from the reaction gas exhaust pipe 12 by the exhaust pump 13.
- the inside space of the cylindrical support member 3 closed at both ends by the ceramics holder 2 and the reaction vessel 1 can be maintained in an inert gas atmosphere.
- the reaction gas containing corrosive gas such as halogen in the reaction vessel 1 enters the cylindrical support member 3, and the air, which is an oxidizing atmosphere, enters the cylindrical support member 3 from outside the apparatus. Can be prevented.
- any gas that does not cause a reaction that degrades the electrode constituent material may be used, but a rare gas group element such as He, Ne, Ar, Kr, Xe, or Rn.
- a rare gas group element such as He, Ne, Ar, Kr, Xe, or Rn.
- N 2 gas can be used, and N 2 or Ar is particularly preferable in terms of cost and the like.

- the inert gas supply pipe 4 inserted into the cylindrical support member 3 opens near the ceramic holder 2, and the inert gas exhaust pipe 5 near the bottom of the reaction vessel 1. It is open. Therefore, the atmosphere of the inert gas in the cylindrical support member 3 is less than 0.1 IMPa (1 atm), and is directed from the ceramic holder 2 side where the electrode 8 is present to the bottom side of the reaction vessel 1. As a result, a pressure distribution of the inert gas can be created so that the pressure gradually becomes low.
- the inert gas supply pipe 4 and the inert gas exhaust pipe 5 both open near the bottom of the reaction vessel 1. Therefore, the inert gas atmosphere in the cylindrical support member 3 is less than 0.1 IMP a (1 atm), and the inert gas atmosphere in the inert gas exhaust pipe 5 is changed from the cylindrical support member 3 side. A pressure distribution of the inert gas can be created so that the pressure gradually decreases toward the exhaust pump 6.
- the pressure of the inert gas atmosphere in the cylindrical support member 3 near the bottom of the reaction vessel 1 becomes higher than the pressure of the reaction gas in the reaction vessel 1, It is possible to effectively prevent intrusion of the reaction gas from the bottom and air from the exhaust pump 6 side. Even if a small amount of corrosive reaction gas diffuses from the inside of the reaction vessel 1, it is immediately exhausted from the inert gas exhaust pipe 5 through the exhaust pump 6, so that the electrode 8 is always covered with an inert gas atmosphere, and corrosion and oxidation are caused. There is no fear. Therefore, the same effect as in the case of FIG. 1 can be expected in the apparatus of FIG.
- the inert gas exhaust pipe 5 and the reaction gas exhaust pipe 12 for exhausting the reaction gas supplied into the reaction vessel 1 are merged on the way, and originally installed separately. By sharing the exhaust pump and consolidating it into one exhaust pump 14, installation space can be reduced.
- the inert gas exhaust pipe 5 and the reaction gas exhaust pipe 12 are partially used. It can have a double structure. Since the pipe structure having the double structure produces an assembling effect, the corrosive reaction gas in the reaction vessel 1 can be effectively prevented from entering the cylindrical support member 3.
- a partition plate 15 is provided between a ceramic holder 2 and the bottom of a reaction vessel 1 in a cylindrical support member 3.
- the inert gas supply pipe 4 is opened in the space between the partition plate 15 and the ceramic holder 2, and an inert gas vent 16 is provided through the partition plate 15 to provide an inert gas.
- the exhaust pipe 5 can be opened between the partition plate 15 and the bottom of the reaction vessel 1.

- a 1 N ceramic holder and a tubular support member were produced in the same manner as in Example 1 above.
- the CVD apparatus shown in FIG. 2, that is, the inert gas supply pipe 4 was closed inside the cylindrical support member 3 near the bottom of the reaction vessel 1 was used in the example. 1 (Fig. 1).
- the other end of the cylindrical support member 3 was fixed to the bottom of the reaction vessel 1 with a clamp, and no air-tight seal using a 0-ring or the like was performed.
- the inside of the cylindrical support member 3 was evacuated while supplying N 2 gas, thereby keeping the inside of the cylindrical support member 3 at less than 0.1 IMPa (1 atm).
- the TiCl 4 + NH 3 is evacuated while flowing into the reaction vessel 1, and the ceramic holder 2 is heated to 600 ° C, thereby depositing TiN on the wafer 10 placed on the workpiece holding surface. did.
- Example 1 As a result of this Tin vapor deposition test, the power consumption was 100% when Example 1 was set to 100%.
