    摘要: A single-substrate-processing CVD apparatus is used for forming a BST thin film on a semiconductor wafer while supplying a first process gas containing a mixture of Ba(thd).sub.2 and Sr(thd).sub.2, and a second process gas containing Ti(O-iPr)(thd).sub.2 or Ti(thd).sub.2. Precursors of Ba and Sr have lower activation energies and higher resistivities than precursors of Ti. The first and second process gases are supplied from a shower head which has a group of first spouting holes for spouting the first process gas and a group of second spouting holes for spouting the second process gas. The group of the second spouting holes are designed to have diameters gradually decreasing in radial directions outward from the center of a shower region, such that the second process gas is supplied at a spouting rate gradually decreasing in radial directions outward from the center.

    摘要: In a thin film forming method of the invention, an atmosphere for a base as a thin film forming target is set to a high vacuum of, e.g., 0.01 Torr or less, and a gas of an organometallic compound and an oxidizing gas are introduced onto a base surface heated to about 450° C., to form a plurality of crystal nuclei, made of an oxide of a metal constituting the organometallic compound, on the base surface. The atmosphere for the base is then set to a lower vacuum than the first vacuum degree, and the gas of the organometallic compound and the oxidizing gas are subsequently introduced onto the base surface heated to about 45° C., to form a film made of the oxide of the metal there. In the above process, in the first step, the vacuum degree is set to a vacuum degree at which the oxide of the metal is formed by crystal growth on surfaces of different materials at the first temperature, and the plurality of crystal nuclei are formed at a high density so that a crystal grain which is formed by growing a crystal nucleus comes into contact with a crystal grain growing from an adjacent crystal nucleus. In the subsequent step, the temperature for the base is set to less than a temperature at which the oxide of the metal is formed by crystal growth on the surfaces of the different materials.

    摘要: A method for liquefying a feed gas stream. A refrigerant stream is cooled and expanded to produce an expanded, cooled refrigerant stream. Part or all of the expanded, cooled refrigerant stream is mixed with a make-up refrigerant stream in a separator, thereby condensing heavy hydrocarbon components from the make-up refrigerant stream and forming a gaseous expanded, cooled refrigerant stream. The gaseous expanded, cooled refrigerant stream passes through a heat exchanger zone to form a warm refrigerant stream. The feed gas stream is passed through the heat exchanger zone to cool at least part of the feed gas stream by indirect heat exchange with the expanded, cooled refrigerant stream, thereby forming a liquefied gas stream. The warm refrigerant stream is compressed to produce the compressed refrigerant stream.
