  • Patent number: 11387116
    Abstract: In a manufacturing process of a transistor including an oxide semiconductor film, oxygen doping treatment is performed on the oxide semiconductor film, and then heat treatment is performed on the oxide semiconductor film and an aluminum oxide film provided over the oxide semiconductor film. Consequently, an oxide semiconductor film which includes a region containing more oxygen than a stoichiometric composition is formed. The transistor formed using the oxide semiconductor film can have high reliability because the amount of change in the threshold voltage of the transistor by a bias-temperature stress test (BT test) is reduced.

  • Patent number: 10594943
    Abstract: The present invention provides a camera calibration device and a camera calibration system with which it is possible to execute calibration even in a situation where the load-bearing state of a vehicle changes, and also to precisely estimate all of camera parameters and execute calibration without utilizing the parallelism of the vehicle to, e.g., a white line. The orientation of a vehicle is estimated on the basis of a prescribed feature amount extracted from a video, the translation-direction position of a camera relative to ground is corrected on the basis of information obtained from the calibration executed at a time in the past such as the time of product shipment, and a camera parameter pertaining to the orientation of the camera relative to ground is calculated on the basis of the orientation of the vehicle and the translation-direction position of the camera relative to ground.
