Abstract: Provided are a silicon nitride film etching composition, a method of etching a silicon nitride film using the same, and a manufacturing method of a semiconductor device. Specifically, a silicon nitride film may be highly selectively etched as compared with a silicon oxide film, and when the composition is applied to an etching process at a high temperature and a semiconductor manufacturing process, not only no precipitate occurs but also anomalous growth in which the thickness of the silicon oxide film is rather increased does not occur, thereby minimizing defects and reliability reduction.

Abstract: The chuck for supporting a target substrate for a display device, the chuck includes: a base having a first surface to support an object and a second surface opposite the first surface, the first surface including a first area and a second area; and indentations formed in the second area and recessed from the first area in a thickness direction of the base. The indentations include a first indentation extending in a first direction and a second indentation extending in a second direction intersecting the first direction.

Abstract: An embodiment relates to a lens actuator and a camera module including same. A lens actuator according to an embodiment may comprise: a base; a pin coupled to the base; a housing including a group of lenses to be moved along the pin in an optical axis direction; a magnet disposed on one side of the housing; a yoke spaced apart from the magnet; and a coil disposed between the magnet and the yoke. The housing may include a guide hole disposed at one side thereof and a guide groove disposed at the other side thereof. The pin may include a first pin disposed in the guide hole, and a second pin disposed in the guide groove. An attractive force may be applied between the yoke and the magnet.

Abstract: An apparatus for controlling object tracking and a method therefor are provided. The apparatus includes an object detector configured to detect an object in an image, an object tracker configured to track the object, a learning device configured to learn whether to enable the object detector based on features of the object and tracking results of the object tracker, and a controller configured to determine whether to enable the object detector by interworking with the learning device.

Abstract: A multilayer electronic component according to an exemplary embodiment of the present disclosure may control connectivity of an end of an internal electrode, thereby suppressing occurrence of a short circuit between the internal electrodes, reduced capacitance or lower breakdown voltage. The internal electrode may include a plurality of conductor portions and a plurality of cut-off portions.

Abstract: A semiconductor package includes an interposer, an electronic device having a first side surface and a second side surface opposite to the first side surface, and including a plurality of memory dies stacked in a vertical direction, at least one first through pipe passing through the electronic device in the vertical direction adjacent to the first side surface, and moving a cooling liquid therein, and a plurality of thermal transmission lines extending in a horizontal direction inside the memory die, and extending in parallel from the first through pipe toward the second side surface.

Abstract: An aspect of the present disclosure provides a bus bar as a winding in a core of a transformer includes multiple sub-bars arranged horizontally and connected in parallel so as to minimize an AC current in the transformer, and the sub-bars have different widths and thus resistances or impedances with respect to a current flowing through the sub-bars are the same. Another aspect of the present disclosure provides a method of designing a bus bar for resistance or impedance matching between multiple sub-bars included in the bus bar to share a current to minimize an AC current in the transformer. Another aspect of the present disclosure provides a transformer, for a DC-DC converter for use in a vehicle, which is manufactured by the method of designing a bus bar.

Abstract: The present invention relates to a novel enzyme capable of producing multi-hydroxy derivatives from polyunsaturated fatty acids and a method for producing multi-hydroxy derivatives of polyunsaturated fatty acids using the same.

Abstract: An apparatus and a method are provided for operating HARQ in a mobile communication system. The method includes receiving a number of HARQ processes of a semi-persistent resource allocation and semi-persistent resource allocation interval information for a first transmission; receiving data in the first transmission at a subframe based on the semi-persistent resource allocation interval information; calculating a HARQ process IDentifier (ID) using the number of HARQ processes of the semi-persistent resource allocation, the semi-persistent resource allocation interval information, and time information; receiving control information including the HARQ process ID on an L1 control channel; receiving data in a retransmission based on the control information including the HARQ process ID; combining the data received in the first transmission and the data received in the retransmission; and decoding the combined data.
