During a process of forming an active layer of a semiconductor device using a ZnO film, the ZnO film is laser-annealed with an ultraviolet pulsed laser to reduce the resistance of the film, and then oxidation treatment is applied to increase the specific resistance value at a channel portion of the ZnO film, which once has excessively low resistance after the laser annealing, to 103Ω·cm or more.
摘要:
In a process for producing an oriented inorganic crystalline film, a non-monocrystalline film containing inorganic crystalline particles is formed on a substrate by a liquid phase technique using a raw-material solution which contains a raw material and an organic solvent, where the inorganic crystalline particles have a layered crystal structure and are contained in the raw material. Then, the non-monocrystalline film is crystallized by heating the non-monocrystalline film to a temperature equal to or higher than the crystallization temperature of the non-monocrystalline film so that part of the inorganic crystalline particles act as crystal nuclei.

摘要:
A D-E hysteresis loop of ferroelectrics known in the art has a square shape when the ferroelectrics are a BaTiO.sub.3 single crystal. Such ferroelectrics are used as a non-linear dielectric element of, for example a pulse generating device. The non-linear dielectric element according to the present invention consists of a polycrystal, which is mainly composed of BaTiO.sub.3 and has the chemical composition expressed by the formula A.sub.y B.sub.z O.sub.3, wherein the molar ratio of y/z ranges from 0.92 to 0.99. The non-linearity is excellent and the temperature dependence of the A.sub.y B.sub.z O.sub.3 composition is considerably low.

摘要:
A gate electrode, a gate insulation film and an inorganic oxide film are formed in this order on a substrate, and a source electrode and a drain electrode are formed to partially cover the inorganic oxide film. Then, oxidation treatment is applied to reduce the carrier density at a region of the inorganic oxide film which is not covered by the electrodes and is used as a channel region of a semiconductor device.
