摘要:
A method for manufacturing a semiconductor device having a movable portion includes the steps of: forming a trench on a semiconductor layer so that the trench reaches an insulation layer; and forming a movable portion by etching a sidewall of the trench so that the semiconductor layer is separated from the insulation layer. The steps of forming the trench and forming the movable portion are performed by a reactive ion etching method. The insulation layer disposed on the bottom of the trench is prevented from charging positively in the step of forming the trench. The insulation layer disposed on the bottom of the trench is charged positively in the step of forming the movable portion.

If a user wish to print files to be printed in accordance with a specific print setting, the user may store the file in a predetermined area of the external storage that is preliminarily associated with the predetermined print setting. When the printing device starts printing, files stored in the predetermined area are printed in accordance with the print setting associated to the predetermined area. Therefore, the printing device can reduce a user's burden in performing a relatively complicated print setting, while enabling print setting along with the user's demand.

A process for fabricating a blue-emitting SrS:Ce based electroluminescent device, which improves in brightness and blue color purity of the electroluminescent device, is disclosed. The blue-emitting luminescent layer of the device is formed as follows: a luminescent layer based on strontium sulfide (SrS) with cerium (Ce) doped at a concentration in a range of 0.01% by atomic or higher but less than 0.3% by atomic is deposited; and then heat treatment is applied thereto at a temperature in a range of 400.degree. C. or higher but 550.degree. C. or lower before forming any other layer thereon.

An image scanning device has a scanning unit, a first storage unit, a first determination unit, and a control unit. The scanning unit scans an original document to produce image data. The first storage unit stores a specific condition used by the scanning unit for scanning a specific document. The specific document requires a limited scanning condition. The first determination unit determines based on the image data whether the original document is the specific document. The control unit reads the specific condition from the first storage unit and causes the scanning unit to scan the original document with the specific condition if the first determination unit determines that the original document is the specific document.

A semiconductor device includes: a sensor element having a plate shape with a surface and including a sensor structure disposed in a surface portion of the sensor element; and a plate-shaped cap element bonded to the surface of the sensor element. The cap element has a wiring pattern portion facing the sensor element. The wiring pattern portion connects an outer periphery of the surface of the sensor element and the sensor structure so that the sensor structure is electrically coupled with an external element via the outer periphery. The sensor element does not have a complicated multi-layered structure, so that the sensor element is simplified. Further, the dimensions of the device are reduced.
