Abstract: The present application provides a method for fabricating multiple work function layers, including: forming the first to the nth transistor gates with notches; forming a blocking layer in the notches; depositing the first work function layer and removing the first work function layer on the first to the (n?1)th transistor gates; depositing a second work function layer; removing the second work function layer on the first to the (n?2)th transistor gates; depositing a third work function layer on the blocking layer on the first to the (n?2)th transistor gates and the second work function layer on the (n?1)th and nth transistor gates; removing the third work function layer on the first to (n?3)th transistor gates; depositing the third to the (n?1)th work function layers by analogy until only the blocking layer exists on the last transistor gate, herein the thickness of the third to the (n?1)th work function layers decreases sequentially and gradually.

Abstract: The present disclosure provides a flight processing method applied to a control device of an unmanned aerial vehicle (UAV). The method includes obtaining a clearance permission file of a target flight restriction area from a server, the clearance permission file being generated by the server in response to flight clearance application information of the flight restriction removal conditions obtained from a smart terminal; and removing flight restrictions of the UAV in the target flight restriction area based on the clearance permission file.

Abstract: A method for controlling an unmanned aerial vehicle includes receiving update data of a flight restriction database of the unmanned aerial vehicle returned by a server in response to an updating request and carrying current position information of the unmanned aerial vehicle, and, if the update data satisfies a condition controlling, controlling flight of the unmanned aerial vehicle according to the update data.

Abstract: A method for managing flight restricted regions for an unmanned aerial vehicle (UAV) includes an application processor receiving region information regarding the flight restricted regions from a database and processing the region information to obtain positional information of the flight restricted regions relative to the UAV, and a flight controller receiving the positional information of the flight restricted regions relative to the UAV and controlling flight of the UAV based on the received positional information. The flight controller is in communication with the application processor.

Abstract: A method for determining a flight strategy of an unmanned aerial vehicle includes determining a position of a ground device communicating with the unmanned aerial vehicle; determining a first flight state of the unmanned aerial vehicle according to the position of the ground device and a flight-restriction zone; and determining a scene of the unmanned aerial vehicle and the flight strategy corresponding to the scene according to the first flight state of the unmanned aerial vehicle.

Abstract: A flight restriction data update method includes sending an updating request to a server in response to an update triggering condition being satisfied, and receiving update data for a dynamic flight restriction database of a requesting device. The updating request includes current location information of the requesting device, and the update data is returned by the server according to the current location information.

Abstract: A method for supporting flight restriction of aircraft includes generating a flight restriction region using one or more three-dimensional elementary flight restriction volumes, and controlling the aircraft according to the flight restriction region. The one or more elementary flight restriction volumes are configured to require the aircraft to take one or more flight response measures based on at least one of (1) location of the aircraft, or (2) movement characteristic of the aircraft relative to the one or more elementary flight restriction volumes.
