  • Publication number: 20240180041
    Abstract: The present invention relates to a heterojunction semiconductor substrate having excellent dielectric properties, a method of manufacturing the same, and an electronic device using the same. The present invention provides a heterojunction semiconductor substrate with improved interlayer adhesion, low leakage current, and excellent dielectric properties that maintain strength in a ferroelectric fatigue experiment by interposing a metal layer and a conductive metal oxide layer on a semiconductor substrate to form an epitaxial oxide thin film layer composed of perovskite piezoelectric oxide. The heterojunction semiconductor substrate can be applied to sensors, actuators, transducers, or MEMS devices that use the high functionality of the high-quality epitaxial oxide thin film layer, including applications in electronic and optical devices.

  • Patent number: 11186272
    Abstract: A control method for an electronic limited slip differential of a vehicle includes: determining by a controller, whether the vehicle is in an understeer state or an oversteer state when the vehicle is turning; and performing driving force movement control by the controller. In particular, when the vehicle is in the understeer state and an actual driving force of an inner wheel of the vehicle is greater than an allowable driving force of inner wheel, the controller increases the control torque of the electronic limited slip differential and transfers the inner wheel driving force to the outer wheel of the vehicle.
