The dielectric layer has a stacked layer structure including a predetermined number of hafnium oxide sublayers and predetermined number of tantalum oxide sublayers. The number, materials, and thicknesses of the sublayers are determined so that the thickness ratio has a range in which, in voltage-leakage current characteristics showing the relationship between the voltage between the first and second electrodes and the leakage current, a start voltage at which the slope of an increase in the current starts to discontinuously increase satisfies an electric field strength of 3 [MV/cm] or more when the ratio of the total thickness of the predetermined number of tantalum oxide sublayers to the total thickness of the dielectric layer is varied, and the thickness ratio is within the range such that the start voltage is within the range.

摘要:
A film deposition process for depositing an amorphous metal oxide film, for example, an amorphous tantalum oxide film, and a film treatment process for improving the film quality of the amorphous tantalum oxide film in the state in which an amorphous state of the amorphous metal oxide film is maintained by a high-density plasma radiation treatment based upon ion and radical reactions, and which contains at least oxygen at an ion current density higher than 5 mA/cm2 are carried out, whereby a low-temperature treatment in the whole process is made possible. In addition, since the amorphous metal oxide film, which is excellent in film quality, can be deposited, the amorphous metal oxide film can be made high in reliability and can be produced inexpensively. The amorphous tantalum oxide film, which is excellent in film quality, can be manufactured inexpensively by a low-temperature treatment. Also, when a capacitance element having an amorphous metal oxide film and a semiconductor device are manufactured, the amorphous metal oxide film, which is excellent in film quality, can be deposited by a low-temperature treatment and a highly-reliable capacitance element and semiconductor device can be manufactured.

Picture element electrodes (7) are electrically connected with drain electrodes (18D) of respective transistor elements (18). The picture element electrodes (7) and data signal lines (SLn, SLn+1, . . . ) are provided above scanning signal lines (GLn, GLn+1, . . . ). The picture element electrodes (7) overlap scanning signal lines (GLn, GLn+1, . . . ) when viewed from above. Notch parts 7a and 7b are provided in each picture element electrode (7) so as to overlap each of the scanning signal lines (GLn, GLn+1, . . . ). Shield electrodes (4a, 4b) are formed in the same layer as the data signal lines (SLn, SLn+1, . . . ). Each of the scanning signal lines (GLn, GLn+1, . . . ) at least partially overlaps the shield electrodes (4a, 4b) in the notch parts (7a, 7b), when viewed from above. This provides the liquid crystal display panel having wide viewing angle characteristic and carrying out high quality display.
