Two layers of protection films are formed such that a sheet resistance at a portion directly below the protection film is higher than that at a portion directly below the protection film. The protection films are formed, for example, of SiN film, as insulating films. The protection film is formed to be higher, for instance, in hydrogen concentration than the protection film so that the protection film is higher in refractive index the protection film. The protection film is formed to cover a gate electrode and extend to the vicinity of the gate electrode on an electron supplying layer. The protection film is formed on the entire surface to cover the protection film. According to this configuration, the gate leakage is significantly reduced by a relatively simple configuration to realize a highly-reliable compound semiconductor device achieving high voltage operation, high withstand voltage, and high output.

A refrigeration system includes an outdoor unit having a refrigeration compressor and a heat exchanger, and an indoor unit having a heat exchanger to be placed where air conditioning is desired. In installing the refrigeration system, the outdoor unit is first connected with the indoor unit via pipe lines, and an air absorbing device containing zeolite as an adsorbent is subsequently placed on the outdoor unit, the indoor unit, or the pipe lines to remove air. The air absorbing device is then separated from the refrigeration system, and refrigerant is caused to circulate through the refrigeration system.

PURPOSE: To obtain an oriented laminated film which is improved in carrier mobility by improving the orientation of crystals in a conductive oligomer at the time of using the oligomer for an electronic element and, at the same time, to obtain an organic electronic element by using the oriented laminated film. CONSTITUTION: After forming a gate insulating layer 12 a about 500nm thick on a silicon substrate 11, a fluoro-polymer layer 13 having about 5μm thick is formed on the layer 12 by uniformly spin-coating a fluoro-polymer to the surface of the layer 12. Then an oriented film is formed by rubbing the layer 13 with a rubbing device 14. Then comb-shaped source and drain electrodes 15 composed of chromium and gold are formed on the oriented polymer film 13 by using a vacuum evaporation device and a conductive oligomer layer 16 about 50nm thick is formed as an oriented laminated film 17 on and between the electrodes 15 by the vapor deposition method from a gaseous phase or by the casting method from a solution. Thereafter, the substrate 11 itself is formed to a gate electrode 18 after polishing the side of the substrate 11 on which no electrode is formed and removing the surface layer from the substrate 11.
