    摘要: Disclosed is an MOCVD method of forming a tantalum oxide film. First, water vapor used as an oxidizing agent is supplied into a process container to cause moisture to be adsorbed on a surface of each semiconductor wafer. Then, PET gas used as a raw material gas is supplied into the process container and is caused to react with the moisture on the wafer at a process temperature of 200° C., thereby forming an interface layer of tantalum oxide. Then, PET gas and oxygen gas are supplied into the process container at the same time, and are caused to react with each other at a process temperature of 410° C., thereby forming a main layer of tantalum oxide on the interface layer.

    摘要: A method of fabricating a semiconductor device according to one embodiment includes: forming a SiGe crystal layer on a semiconductor substrate, the SiGe crystal layer having a first plane and a second plane inclined with respect to the first plane; forming an amorphous Si film on the SiGe crystal layer; crystallizing a portion located adjacent to the first and second planes of the amorphous Si film by applying heat treatment using the first and second planes of the SiGe crystal layer as a seed, thereby forming a Si crystal layer; selectively removing or thinning a portion of the amorphous Si film that is not crystallized by the heat treatment; applying oxidation treatment to a surface of the Si crystal layer, thereby forming a gate insulating film on the surface of the Si crystal layer; and forming a gate electrode on the gate insulating film.
