  • Patent number: 7230216
    Abstract: It is an object of the present invention to prevent temperature decrease in a border portion of each of heating coils and to enable to eliminate an influence given by the change in a load state. In order to attain this object, an induction heating unit according to the present invention is provided with control units respectively corresponding to a plurality of heating units. A phase detector of the control unit obtains a phase difference between an output current (heating coil current) of an inverter detected by a current transformer reference signal outputted by a reference signal generating section, and inputs it to a drive control section. The drive control section adjusts an output timing (phase) of a gate pulse to be given to the inverter so as to make a phase of the heating coil current of the inverter coincide with a phase of the reference signal outputted by the reference signal generating section.

  • Patent number: 7087980
    Abstract: The object of the present invention is to provide a wafer having a structure of enabling an SiC wafer to be put to practical use as a wafer for monitoring a film thickness. For this purpose, an average surface roughness Ra of at least one surface of the SiC wafer is set to be substantially equivalent to a film thickness of a film to be deposited on an Si wafer to be measured. If several types are available to be deposited on an Si wafer to be measured, a minimum film thickness of the film among the several types is determined as an upper limit value, and the average surface roughness Ra of the film thickness measuring SiC wafer is set less than the upper limit value. More concretely, the surface roughness is set to be about 400 times as large as the average surface roughness of a product Si wafer, Ra being preferably set to be 0.08 ?m or less.

  • Patent number: 7022545
    Abstract: 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.
