A power semiconductor device and a method of manufacturing the power semiconductor device are disclosed. The power semiconductor device includes an isolation region at or in a bather layer in contact with or adjacent to a drain electrode to reduce or prevent current collapse between a gate electrode and the drain electrode.

Power semiconductor device and manufacturing method thereof

Disclosed is a power semiconductor device and a manufacturing method thereof and, more particularly, a power semiconductor device and a manufacturing method thereof seeking to capture electrons trapped on one side of a transistor during transistor operation, prevent current collapse effects, and improve reliability consequently by forming or including one or more hole injection regions in a separation space between a gate electrode and a drain electrode.

Artificial intelligence avatar-based interaction service is performed in a system including an unmanned information terminal and an interaction service device. A sound signal is collected from a microphone array mounted in the unmanned information terminal and an image signal collected from a vision sensor to the interaction service device. A sensing area is set based on the received sound signal and image signal by the interaction service device; recognizing an active speaker based on a voice signal of a user and an image signal of the user collected in the sensing area, by the interaction service device. A response for the recognized active speaker is generated to provide a 3D rendering an artificial intelligence avatar to which the response is reflected. The rendered artificial intelligence avatar is provided to the unmanned information terminal by the interaction service device.

AI avatar-based interaction service method and apparatus

Provided is a traffic information collecting method using big data of an outside image of a vehicle. According to the present disclosure, a traffic information collecting method using big data of an outside image of a vehicle includes: generating object classification information indicating information on at least one of a position, a type, and a status of at least one object included in an image obtained by photographing an external situation of a vehicle; generating situation analysis information which is information obtained by analyzing the external situation of the vehicle, based on the object classification information; and selectively transmitting the situation analysis information to a server based on whether the situation analysis information corresponds to a passage interruption event which is an incident interrupting passage of the vehicle.
