摘要： A method of performing anisotropic etching more than once with respect to a semiconductor substrate (1) is provided with the steps of performing first-time anisotropic etching by using a first etching mask (2) so as to form a first anisotropically etched region (4) which is hollow, forming a second etching mask (7) over the first etching mask (2), performing second-time anisotropic etching by using the second etching mask (7), and previously forming the first etching mask (2) from a material which is resistant to an etchant used for patterning the second etching mask (7) before the first-time anisotropic etching is performed. Thus, the edge portion (6) of the first etched region (4) is protected so that its configuration is excellently maintained. By way of example, either of the etching masks is composed of a dielectric material such as a silicon dioxide film, while the other etching mask is composed of a metallic material such as Au and Ti, and the second-time anisotropic etching is performed by using diluted potassium hydroxide.

摘要： Provided is a backlight device, wherein when both the drive duty and the drive current are controlled in each of separated areas, the image quality is improved by preventing the change of luminance even when there is a difference between the adjustment resolutions of both the drive duty and the drive current. A light-emitting unit (121) comprises a plurality of light-emitting areas. A motion amount detecting unit (131) detects the motion amount of an image in each of a plurality of motion areas each corresponding to at least one or more light-emitting areas. A drive condition specifying unit specifies a drive condition including the duty and pulse height value of a drive pulse for causing each of the plurality of light-emitting areas to emit light, on the basis of the detected motion amount. A drive unit drives each of the plurality of light-emitting areas according to the specified drive condition. With one of the duty and the pulse height value of the drive pulse, the adjustment resolution of which of the drive unit with respect to the light emission luminance is lower, as a first parameter and the other the adjustment resolution of which is higher as a second parameter, the drive condition specifying unit determines the value of the first parameter on the basis of the detected motion amount, and thereafter determines the value of the second parameter on the basis of the determined value of the first parameter.
