    Abstract: A highly reliable semiconductor device which includes an oxide semiconductor is provided. Alternatively, a transistor having normally-off characteristics which includes an oxide semiconductor is provided. The transistor includes a first conductor, a first insulator, a second insulator, a third insulator, a first oxide, an oxide semiconductor, a second conductor, a second oxide, a fourth insulator, a third conductor, a fourth conductor, a fifth insulator, and a sixth insulator. The second conductor is separated from the sixth insulator by the second oxide. The third conductor and the fourth conductor are separated from the sixth insulator by the fifth insulator. The second oxide has a function of suppressing permeation of oxygen as long as oxygen contained in the sixth insulator is sufficiently supplied to the oxide semiconductor through the second oxide. The fifth insulator has a barrier property against oxygen.

  • Patent number: 9261437
    Abstract: Sample fine particles attached to an inspection object are identified simply and with high accuracy, and an increase in operation rate and a decrease in device size are achieved. The inspection object is transported into a sampling chamber defined by a pair of side walls and an upper wall enclosing a part of a transport route of a transport unit. The inspection object is sprayed with compressed gas from an air nozzle, the peeled sample fine particles are aspirated into a collector, and the sample fine particles are separated from the aspirated gas for analysis. The air nozzle is disposed on one of the side walls defining the sampling chamber. The collector is disposed under the other side wall as a container independent from the sampling chamber.

  • Publication number: 20150235831
    Abstract: Provided is a technique of analyzing particles in real time while collecting and condensing the particles continuously. Gas and/or particles as a detection target substance that are attached to an authentication target 2 are removed by air flow from a blowing region 5. The removed sample is sucked and is condensed and sampled at a sampling region 10, and ions of the sample are generated at an ion source 21 and are then subjected to mass analysis at a mass analysis region 23. Determination of the obtained mass spectrum is made as to the presence or not of a mass spectrum derived from the detection target substance, and a monitor 27 displays a result thereof. Thereby, the detection target substance attached to the authentication target 2 can be detected continuously in real time, promptly and with a less error rate.
