Filed: 1982-03-16
Abstract: PURPOSE:To obtain an FET of high performance by interposing a ZnS conductive a ZnS conductive film between a thin Si film and an amorphous insulative substrate and employing as a gate insulating film a thin Ta2O3 film. CONSTITUTION:Since a ZnS 6 has a large forbidden band width, it can be regarded as an insulative layer, thereby enable preventing the back channel effect and reducing the threshold voltage and the leakage between the source 7 and the drain 9. Further, since ZnS is arranged in (111) direction on an amorphous insulative plate 5 and Si crystal and lattice constant coincide, a single crystal Si thin film can be grown on the plate by an epitaxial method or CVD method, thereby obtaining high carrier mobility, the boundary characteristics between the  Si and ZnS can be improved, and the withstand voltage of the transistor can  be increased. Further, mobile cations are extremely small in a Ta2O3 film 8, an  inverted region such as between Si and SiO2 is not formed, thereby reducing the threshold voltage. Further, the dielectric constant of Ta2O3 is approx. 7 times that of the SiO2, thereby enable increasing the mutual conductance. The thickness of the Ta2O3 film is selected for the utility of the FET.

Filed: 1995-03-01
Abstract: PURPOSE: To bend and vibrate a vibrator in a stable posture by flattening supporting filaments in the axial direction of the vibrator at least in a part except a connecting part to the vibrator. CONSTITUTION: When a vibrator 1 supported by supporting filaments 21a and 21b is bent and vibrated in a necessary amplitude in the Y axis direction by an action of a piezoelectric means, an electromagnetic means or the like, the filaments 21a and 21b are particularly largely deformed in the Z axis direction in flat parts 23a and 23b whose second moment of area is small. The bending moment acting on a connecting part to the vibrator 1 by its filaments 21a and 21b becomes smaller, and deflective deformation generated in its part also becomes smaller. Therefore, pressing force exerted on respective side surfaces of the vibrator 1 by its connecting part of the filaments 21a and 21b also becomes smaller, and component force in the X axis direction and the Z axis direction of respective pressing forces also becomes smaller.  Therefore, bending vibration in the Y axis direction of the vibrator 1 is extremely stabilized.
