Abstract: One object is to provide a semiconductor device including an oxide semiconductor, which has stable electric characteristics and high reliability. Another object is to manufacture a highly reliable semiconductor device in a high yield. In a top-gate staggered transistor including an oxide semiconductor film, as a first gate insulating film in contact with the oxide semiconductor film, a silicon oxide film is formed by a plasma CVD method with use of a deposition gas containing silicon fluoride and oxygen; and as a second gate insulating film stacked over the first gate insulating film, a silicon oxide film is formed by a plasma CVD method with use of a deposition gas containing silicon hydride and oxygen.

Abstract: An electronic device includes a display portion, an imaging portion, a control portion, an input portion, and a sensor portion. The display portion has a first display element that reflects visible light and a second display element that emits visible light. The display portion has a function of displaying an image using one of or both first light reflected by the first display element and second light emitted from the second display element. The imaging portion takes an image of an object, the control portion controls the display portion and the imaging portion, the input portion inputs a signal for controlling the display portion and the imaging portion to the control portion, and the sensor portion outputs sensing data to the control portion, in consideration of illuminance of external light. Such a display device increases the display quality, or keeps high-quality display regardless of environmental conditions and reduces power consumption.

Abstract: Phase-change type, reversible optical information recording medium, being possible for recording, reproducing, erasing, and rewriting of information, by use of a laser beam. This invention consists of recording thin film of ternary elements, for example, containing Ge, Te, Sb/or Bi or quaternary elements containing the fourth element of Se with which a part of Te is replaced, which is established on such surface—flat substrates as glass or plastics. In this case, the component ratio of Te and Se is selected not to be excess for other elements, such as Ge, Sb/or Bi so as to be fixed as stable compounds of stoichiometric compositions of GeTe, Sb2Te3/or Bi2Te3, or GeSe, Sb2Se3/Bi2Se3 when crystallized. Strictly speaking, a concentration of each component is selected to have proper ratio of the number of atomes each other so as to represent whole composition as the sum of each component. By this treatment, it is possible to have high crystallization speed and long cyclability of recording/erasing.
