To solve the foregoing problems, provided is a ZnO-based semiconductor element having an entirely novel function distinct from hitherto, using a ZnO-based semiconductor and organic matter for an active role. An organic electrode 2 is formed on a ZnO-based semiconductor 1, and an Au film 3 is formed on the organic electrode 2. An electrode formed of a multilayer metal film including a Ti film 4 and an Au film 5 is formed on the back surface of the ZnO-based semiconductor 1 so as to be opposed to the organic electrode 2. A bonding interface between the organic electrode 2 and the ZnO-based semiconductor 1 is in a pn junction-like state. Thus, rectification occurs therebetween.

A container of a material supply apparatus is configured of a crucible and an orifice. The crucible has a cylindrical shape, a rectangular-column shape or the like, and is hollow. Heat sources such as heaters are disposed around the crucible. The orifice including an opening is provided on a side of the crucible in a material element supplying direction. The orifice includes a pipe portion that extends in the material element supplying direction. The opening is formed on a tip of the pipe portion. An opening area of the pipe portion is formed to become gradually narrower towards the material element supplying side, namely in a direction of the opening.

A substrate temperature measuring apparatus includes: a heating source that heat a substrate; a transmission window that transmits therethrough an infrared ray in a range of a wavelength at which the infrared ray cannot transmit through the substrate; and a temperature-measuring instrument having a sensitivity range including the range of the wavelength, and measuring a substrate temperature of the substrate by analyzing an infrared ray radiated from the substrate heated by the heating source and having transmitted through the transmission window.
摘要:
Provided is a multilayer substrate having the configuration in which a multilayer film is formed on a principal surface opposite to a principal surface in the oxide-thin-film lamination direction in a translucent substrate. The multilayer film is formed by sequentially laminating a dielectric film, Au (gold) film, and oxide film in this order from the translucent substrate. On the principal surface opposite to the principal surface on which the oxide thin film is disposed, the multilayer film containing the Au film is formed, the Au film can reflect and block the excessive infrared light from a substrate holder or a heat source at the time of growth. As a result, temperature can be accurately measured.
摘要:
The present invention provides a high quality thin film comparable to a bulk single crystal and providres a semiconductor device with superior characteristics. A channel layer 11, for example, is formed of a semiconductor such as zinc oxide ZnO or the like. A source 12, a drain 13, a gate 14 and a gate insulating layer 15 are formed on the channel layer 111 to form an FET. For a substrate 16, a proper material is selected depending on a thin film material of the channel layer 11 in consideration of compatibility of both lattice constants. For example, if ZnO is used for the semiconductor of the channel layer as a base material, ScAlMgO4 or the like can be used for the substrate 16.
