Abstract: PURPOSE:To reduce ununiformity of electric field by forming a capacitor lower electrode of a first part consisting of a silicon crystal having a first grain size and a second part consisting of a silicon crystal having a second grain size. CONSTITUTION:Grain size of crystal of polycrystal silicon forming an erected wall portion 11b is set larger (1000 to 10000Angstrom ) than grain size (200 to 500Angstrom ) of crystal of polycrystal silicon forming a base portion 11a. Since grain size of crystal of polycrystal silicon forming the erected wall portion is larger as described above, the number of microscopic recessed and projected portions at the surface of the erected wall portion 11b is reduced in comparison with the existing numbers. Moreover, with a post-manufacturing process, when the thickness of the erected wall portion 11b is set to 1000Angstrom , the surface roughness of the erected wall portion 11b can be set to 10Angstrom  or less. Thereby, ununiformity of electric field to be applied on a capacitor insulating film 12 covering the erected wall portion 11b can be reduced more than the existing one.

Furthermore, by such a method as to reduce the rate of a lubricating oil circulation and lower a condensation temperature, i.e. a temperature of liquid refrigerant in a gas-liquid separator 4, a high-temperature two-phase separation phenomenon is restrained. Thus, when the refrigerant condition is checked through the sight glass 4a of the gas-liquid separator 4 in a freezing cycle 1, a refrigerant opacity phenomenon which is caused by the high-temperature two-phase separation phenomenon is restrained, and the amount of refrigerant filled is reliably judged. As a result, the excessive filling of refrigerant that is attributable to the high-temperature two-phase separation phenomenon can be prevented.
