Description of the Invention [Technical Field of the Invention] The present invention relates to an organometallic compound supply container. More specifically, it relates to an organometallic compound supply container in which an organometallic compound which is coated with a carrier which is solid at a normal temperature and which is a carrier which is inert to an organometallic compound is supported. 〇 [Prior Art] Organometallic compounds are used as raw materials for compound semiconductors in the electronics industry. When the organometallic compound is used in the electronics industry, a carrier gas such as hydrogen is usually blown into contact with an organometallic compound to form a saturated vapor of an organic gold compound, which is loaded into a vapor phase growth apparatus or the like. In the case of an organometallic compound which is solid at room temperature (room temperature), unlike a liquid, even if a carrier gas is blown, a solid-state organometallic compound which is laminated forms a flow path through which the carrier passes, or is vaporized into small particles. The solid ruthenium organometallic compound of the diameter will accumulate at the bottom of the vessel, and as a result, the solid organometallic compound will not be in sufficient contact with the carrier gas, resulting in the disadvantage that the vapor phase growth apparatus cannot supply a stable concentration of the organometallic compound. The solid organometallic compound at normal temperature is used as a container for obtaining an evaporation amount of an organometallic compound having a certain reproducibility, and it is known that the end portion of the upper portion of the container is vertically disposed before the carrier gas is introduced into the tube. The bottom portion of the carrier gas outlet pipe is disposed at the bottom portion, and the organic metal compound for gas phase growth formed by the carrier-supporting organometallic compound on the carrier which is coated with the organometallic compound on the carrier which is inert to the organometallic compound is supplied in the container - 5- 1379018 Replacement 'container (Japanese Unexamined Patent Publication No. 1 - 2655 1 1). In the supply container described in Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. 1 - 2655 1 1 , the amount of evaporation of the organometallic compound having a certain reproducibility is obtained, and in order to increase the efficiency of vapor phase growth, the organic metal compound is made to increase the carrier gas flow rate. When the amount of gasification becomes large, the use rate of the organometallic compound is lowered, that is, when a certain concentration of the organic metal-containing compound gas cannot be obtained, there is a problem that the amount of the organometallic compound remaining in the supply container increases. . Further, after the organic metal compound remaining in the supply container is taken out, the inside of the container is washed, and the container is reused. SUMMARY OF THE INVENTION The object of the present invention is to provide an evaporation amount of an organic gold compound having a certain reproducibility, which increases the carrier gas flow rate, and when the amount of vaporization of the organometallic compound increases, the organic content can be reduced. The organometallic compound whose metal compound usage is lowered is supplied to the container. In order to solve this problem, the inventors of the present invention have found that the crucible is used for the front end of the carrier gas introduction pipe which is inclined 20 to 50° in the horizontal direction in the upper portion of the container, and the front end of the carrier gas discharge pipe is disposed. a container at the bottom, which is filled with an organometallic compound which has been coated with an organometallic compound which is solid at normal temperature on a carrier which is inert to the organometallic compound, and which is supported by the carrier gas before the end of the tube. When the carrier is introduced, the carrier gas containing the vaporized organometallic compound is taken out from the carrier gas outlet tube, and the evaporation amount of the organometallic compound having a certain reproducibility is obtained, so that the carrier gas flow rate is increased, and the gasification amount of the organometallic compound is changed. When it is large, the use rate of the metal compound of -6- 1379018 can be reduced, and the present invention can be completed. That is, the present invention is disposed at the front end of the upper portion of the container where the carrier gas introduction pipe is disposed, and the front end portion of the carrier gas outlet pipe is disposed at the bottom portion, and the organic metal compound which has been covered with solid at room temperature is filled in the container. In the organometallic compound supply container in which the organic metal compound is supported on the carrier which is inert to the organometallic compound, the end portion of the carrier gas introduction pipe is inclined obliquely downward by 20 to 50° in the horizontal direction. The organometallic compound supply container characterized by the organic metal compound supported by the carrier which has been coated with the organometallic compound which is solid at normal temperature on a carrier which is inert to the organometallic compound by using the present invention. In the compound supply container, the evaporation amount of the organometallic compound having a certain reproducibility is obtained, and the flow rate of the carrier gas is increased. When the amount of vaporization of the organometallic compound is increased, the decrease in the use rate of the organometallic compound to be charged can be reduced. [Embodiment] [Best Mode for Carrying Out the Invention] The organometallic compound of the present invention is a solid at room temperature and is used for vapor phase growth, etc., specifically, for example, trimethylindium, dimethylchloroindium, cyclopentane Indium compound such as diene indium, trimethyl indium • trimethyl arsenic addition compound, trimethyl indium • trimethylphosphine addition compound, zinc compound such as ethyl zinc iodide, zinc cyclopentadienide or zinc cyclopentadienyl, methyl An aluminum compound such as dichloroaluminum, a gallium compound such as methyldichlorogallium, dimethylchlorogallium or dimethylbromide, or a dicyclopentadienyl magnesium. 1379018 Further, as a carrier which is inert to the organometallic compound capable of supporting these organometallic compounds, alumina 'cerium oxide, mullite, carbon scrap, graphite, potassium titanate, quartz can be used. Ceramics such as tantalum nitride, boron nitride, and tantalum carbide are metals such as stainless steel, aluminum, nickel, and tungsten, fluororesins, and glass. The shape of the carrier is not particularly limited, and generally, various shapes such as an indefinite shape, a spherical shape, a fibrous shape, a mesh shape, a spiral shape, and a circular tube shape can be used. Preferably, the carrier has a larger specific surface area, and the surface of the carrier preferably has a fine unevenness of about 100 to 2000 /zm, or the carrier itself has a plurality of pores (voids). . Examples of such carriers are: alumina balls, iridium rings, Hurricane filling, Dickson pads, stainless steel sintered components, glass wool, and the like. The method of supporting the organometallic compound on the carrier can be carried out by a method generally carried out in the past. For example, a predetermined weight ratio of the carrier and the organometallic compound is added to the vessel, and the organometallic compound is melted by heating, and then the mixture is continuously cooled by rotary stirring, and the carrier is heated and melted in the organometallic compound, followed by extraction. An example of a method of cooling after the molten organometallic compound is excessive. When carrying the load, it is important to remove oxygen, moisture, and other volatile impurities contained in the carrier in advance. When oxygen, moisture, and the like are present on the surface of the carrier, the organometallic compound is deteriorated and contaminated. Therefore, when used for vapor phase growth, not only the quality of the obtained film is impaired, but also the raw material of the object of the present invention. Unable to supply. In order to avoid such conditions, the carrier is continuously heated at a temperature pre-existing at the temperature of its material while performing the normal degassing of '-8-879018' and replacing the void portion with an inert gas such as nitrogen or argon. It is appropriate. The organometallic compound supported on the carrier is usually from about 10 to 100 parts by weight, preferably from about 20 to 70 parts by weight, per 100 parts by weight of the carrier. When the amount is less than 10 parts by weight, since the amount of the organometallic compound in the container volume is small, the container must be enlarged, which is not preferable in an economical manner. On the other hand, when the load is carried out in excess of about 100 parts by weight, the surface area of the organometallic compound in the unit charge volume is not as large as expected when it is not supported. Therefore, the object of the present invention cannot be effectively obtained. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic cross-sectional view showing an embodiment of an organometallic compound supply container of the present invention. The container 1 usually uses a cylindrical shape having a curved bottom. The upper part of the container 1 is provided with a carrier gas introduction pipe 2 and a carrier gas outlet pipe 4, and the end portion 3 of the carrier gas introduction pipe is inclined obliquely downward by 20 to 50 ° in the horizontal direction, preferably 25 to 45°. . The front end portion 5 of the carrier gas outlet pipe is disposed at the bottom of the container. The inside of the container is filled with an organic metal compound 6 supported on a carrier. 4 is a cross-sectional schematic view showing a prior art organometallic compound supply container. The supply container of the present invention is lower than the supply container vertically disposed at the front end portion 3 of the carrier gas introduction tube of the prior art, and is a carrier gas introduction tube. The front end portion 3 is different in that it is inclined by about 20 to 50 degrees. Further, the container 1 is provided with an organic metal compound and a carrier, or an input port (not shown) for supporting the organic metal compound of the carrier. The carrier gas introduction pipe 2 and the carrier gas outlet pipe 4 are disposed on the upper portion of the container as shown in Fig. 1. As long as the carrier gas introduction pipe is disposed at the upper end portion 3 of the container, the front end portion 5 of the carrier gas outlet pipe is disposed. At the bottom of the container, the carrier gas introduction tube 2 and the carrier gas outlet tube 4 may also be disposed at the side of the container. -9 - 1379018 Before the carrier gas introduction pipe, the end portion 3 is inclined at an angle of about 20 to 50° obliquely downward in the horizontal direction, and is inclined from the position away from the central axis of the container toward the side wall of the container. Fig. 2 is a schematic cross-sectional view showing the arrangement of the end portions in the plane direction before the carrier gas introduction pipe. The carrier gas introduction pipe 2 is disposed at a position away from the central axis of the cylindrical container, and the front end portion 3 is disposed obliquely to the side wall of the container. With this arrangement, the carrier gas from the front end portion forms a swirling flow and flows (indicated by an arrow in the figure). Fig. 3 is a view showing a configuration example of the front end portion of the carrier gas introduction pipe. In (Α), a part of the opening of the upper plate 7 of the container is inclined obliquely downward in the horizontal direction by about 20 to 50° to constitute a front end portion. In the upper plate 7, a pipe which is inclined obliquely downward in the horizontal direction by about 20 to 50° is disposed on the upper plate 7 to constitute a front end portion. The amount of the organometallic compound carrying the carrier to the container is usually slightly lower than the lower portion of the front end portion of the carrier gas introduction tube, and about 30 to 70 of the container when the organometallic compound is carried on the carrier in the container. Volume %. Generally, the container having a curved bottom is generally used, but it is not limited thereto, and a container such as a cone may be used. From the viewpoint of the ease of manufacture and the supply of a certain concentration of gas stably and efficiently, it is preferred to use a container having a curved bottom. The distance between the bottom of the container and the front end portion 5 of the carrier gas outlet tube is about 2 to 15 mm, preferably 2 to 10 mm, and more preferably 2 to 5 mm. When it is larger than 15 mm, the use rate of the organometallic compound will fall, which is not desirable. In the above method, after the supply container 1 filled with the organometallic compound supported on the carrier is transported to the place of use, the carrier gas outlet pipe 4 is connected to a 1379018 vapor phase growth device or the like (not shown), and the carrier gas The introduction pipe 2 is connected to a supply source of a carrier gas such as hydrogen. After the supply container is kept at a certain temperature and the carrier gas is supplied, the carrier gas is removed from the upper portion of the container to the lower portion by removing the gap of the organometallic compound supporting the carrier, so that the organic metal having a certain concentration at the temperature is obtained. The carrier gas of the compound is supplied to a vapor phase growth apparatus or the like via the carrier gas outlet pipe 4. By using the evaporation amount of the organometallic compound having a certain reproducibility, the use rate of the organometallic compound to be charged can be reduced even when the carrier gas flow rate is increased and the amount of vaporization of the organometallic compound is increased. Hereinafter, the detailed description of the present invention will be made by way of examples, but the present invention is not limited to the embodiments. The following container was used as an organic metal compound supply container. (Container A) A stainless steel container (curved bottom) having an internal volume of 800 ml is the same as the representative mode of Figs. 1, 2, and 3 (A), and a carrier gas introduction pipe 2 is disposed on the upper plate of the container. The carrier gas outlet pipe 4, the carrier and the input port of the organometallic compound. As shown in Fig. 3(A), the end portion of the carrier gas introduction pipe is formed such that a part of the opening portion of the container upper plate 7 is inclined obliquely downward by 30° in the horizontal direction. Further, as shown in Fig. 2, the carrier gas introduction pipe 2 is disposed at a position away from the central axis of the cylindrical container by 'the front end portion 3 is inclined to the side wall of the container. Further, the distance between the bottom of the container and the end portion 5 of the carrier gas outlet pipe -11 - 1379018 is 3 m. (Container B) The end portion is the same as the container A except that the end portion of the container is vertically oriented as shown in Fig. 4 except for the carrier gas introduction tube. After replacing the inside of the vessel and the tube with nitrogen, the carrier is vacuum degassed to make the alumina ball 43 5 g and the trimethyl indium 300 g of about 4 mm φ in the void portion replaced by nitrogen in a nitrogen atmosphere, and then charged into the inlet port. Inside the container. The container which has been filled is heated to a temperature higher than the melting point of trimethyl indium, and the indium triamide is melted, and then the container is rotated while being slowly cooled, and the indium triamide is solidified and supported on the surface of the alumina sphere of the carrier. (Supply of organometallic compound) The hydrogen high-pressure gas container, the flow rate control device, the organometallic compound supply container for charging the above-mentioned carrier-containing organometallic compound, the gas concentration meter, the deep condensing gas valve for trimethyl indium collection, and the pressure are sequentially connected. Control device and vacuum pump. The supply container was placed in a thermostatic bath and maintained at 25 °C. A skin density meter (manufactured by Thomas Zswan Scientific Ichypment Co., Ltd.) was used as a gas concentration meter. Experiment 1: A container A for charging an organometallic compound carrying a carrier A' was supplied with hydrogen gas by a carrier gas introduction tube at 900 ml/min (at atmospheric pressure) to vaporize trimethyl indium, and the concentration of trimethyl indium was measured by a gas concentration meter. -12- 1379018 Experiment 2: Further, the container B for the organometallic compound supporting the carrier was supplied with hydrogen gas at a rate of 900 ml/min (at atmospheric pressure) from a carrier gas introduction tube, and the concentration of trimethyl indium was measured by the same method. Experiment 3: For the container B of the organometallic compound supported on the carrier, hydrogen was supplied from a carrier gas introduction tube at 600 ml/min (at atmospheric pressure), and the concentration of trimethyl indium was measured by the same method. The ratio of the ratio (based on Experiment 1) to the usage rate (the ratio of the amount of trimethyl indium ruthenium to the vaporized xylene indium total weight container during a certain concentration of trimethyl indium gas) was determined.
