摘要： The present invention has its object to make it possible to produce an α-SiC wafer with stability and good reproducibility at low cost without using a seed crystal substrate that is expensive and less available. In each of crucibles 11a, 11b, 11c, and so on, a β-SiC substrate 19 and an SiC raw material 17 are placed to face each other in close proximity. These crucibles are stacked in layers, and placed inside a radiation tube 40. The radiation tube 40 is heated by an induction heating coil 23, radiates radiation heat, and uniformly heats the crucibles 11a, 11b, 11c and so on. The SiC raw material in each of the crucibles is sublimated and recrystallized on a surface of the β-SiC substrate 19.

摘要： From the viewpoint of manufacturing an SiC semiconductor device economically, a present Si device manufacturing line is utilized to make it possible to handle a small-diameter SiC wafer. Polycrystal SiC is grown from at least one surface side of a small-diameter a-SiC single crystal wafer so as to be in a size of an outer diameter corresponding to a handling device of an existing semiconductor manufacturing line, and thereafter the polycrystal SiC on the surface of the α-SiC single crystal wafer is ground to manufacture an increased-diameter SiC of a double structure in which the polycrystal SiC is grown around an outer circumference of the small-diameter α-SiC single crystal wafer.

摘要： The present invention has its object to obtain an SiC monitor wafer which can flatten the surface until particle detection is possible. SiC of a crystal system 3C is deposited on a substrate by a CVD (Chemical Vapor Deposition) method, and the SiC is detached from a substrate. After the SiC surface is flattened by using mechanical polishing alone or in combination with CMP (Chemo Mechanical Polishing), GCIB (Gas Cluster Ion Beam) is irradiated to the surface until the surface roughness becomes Ra=0.5 nm or less and the impurity density of the wafer surface becomes 1*1011 atoms/cm2 or less to produce the SiC monitor wafer.

摘要： Oxygen gas, for example, is introduced into a film forming chamber, and high-frequency power is supplied to a plurality of monopole antennas arranged above a silicon substrate (101) in the film forming chamber to generate a plasma of the introduced oxygen gas, thereby supplying atomic oxygen (123) onto the surface of an aminosilane molecular layer (102). This plasma generation is performed for about 1 sec. With this operation, the adsorption layer (102) adsorbed onto the surface of the silicon substrate (101) is oxidized, thereby forming a silicon oxide layer (112) corresponding to one atomic layer of silicon on the surface of the silicon substrate (101).

摘要： An atomic layer growing apparatus includes a deposition container, a gas supply unit, and an exhaust unit. In the deposition container, an antenna array and a substrate stage are provided. The antenna array is formed by disposing a plurality of antenna elements in parallel, each of the antenna elements being configured by coating a rod-shaped antenna body with a dielectric material. The antenna array generates plasma using one of an oxidizing gas and a nitriding gas. The substrate is placed on the substrate stage. The gas supply unit alternately supplies the source gas and the oxidizing gas toward the substrate stage from a supply hole made in a sidewall of the deposition container when a film is formed on the substrate. The exhaust unit exhausts the source gas and one of the oxidizing gas and the nitriding gas, which are alternately supplied into the deposition container.
