    摘要: An atmospheric CVD apparatus includes a gas head for ejecting reaction gases consisting of SiH.sub.4 gas and O.sub.2 gas, and a stage which is arranged at a position above the gas head and which is rotated while a semiconductor wafer retained on the bottom of the stage is heated to a temperature in the range of 380.degree. C. to 440.degree. C., the distance between the surface of the semiconductor wafer and the gas supply head being set in the range of 8 mm to 25 mm. The flow ratio between the reaction gases is so adjusted that when the flow rate of the O.sub.2 gas is represented as 1.0, that of the SiH.sub.4 gas is represented as 0.07 to 0.10. The apparatus deposits a reaction product film which excels in film thickness uniformity with a satisfactory level of reproducibility. Furthermore, the apparatus involves very little generation of foreign matter, including reaction products in the form of particles sticking to the surface of the semiconductor wafer, thereby making it possible to produce high-quality semiconductor devices.

    摘要: A liquid vaporizing apparatus includes a container for holding a liquid at a constant temperature with a temperature adjustment unit and a gas that does not react with the liquid is bubbled through the liquid in the container to vaporize the liquid. The container for holding the liquid has an internal space above the liquid and a second temperature adjustment unit for controlling the temperature of the internal space separately from the temperature of the liquid in the container. Since the internal space is maintained at a constant temperature, higher than the temperature of the liquid, the quantity of the vaporized liquid produced is stable.
