Abstract: A substrate processing method is provided. The substrate processing method comprises loading a substrate onto a substrate support inside a chamber, forming a plasma inside the chamber, providing a first DC pulse signal to an electromagnet that generates a magnetic field inside the chamber and processing the substrate with the plasma, wherein the first DC pulse signal is repeated at a first period including a first section and a second section subsequent to the first section, the first DC pulse signal has a first level during the first section, and the first DC pulse signal has a second level different from the first level during the second section.

Abstract: An electronic device comprising a metal case having a metal pad attached thereto is disclosed. According to the present invention, the electronic device comprises: a metal case having a metal terminal part formed therein; a metal pad joined to the metal terminal part by laser welding; and a conductive first coating layer coated on one surface of the metal pad, wherein the light reflectivity of the first coating layer is lower than the light reflectivity of the metal pad.

Abstract: A connection terminal device and an electronic device having the same are provided. The connection terminal device includes a connection terminal device body, and a connection terminal connected to the connection terminal device body. The connection terminal device also has a front unit disposed on a front surface of the connection terminal device body, a rear unit disposed on a rear surface of the connection terminal device body, and a support disposed on the rear surface of the connection terminal device body. When force is applied to the connection terminal, supporting force is transferred to the rear unit of the connection terminal device body.

Abstract: A mobile device having at least two antennas can circumvent transmission problems caused by a user's grasp of the device. A sensor unit is disposed at a specific location of a device body and creates a sensor signal by detecting the contact or proximity of a particular object such a user's hand. When receiving the sensor signal, a control unit selects one of the antennas depending on the sensor signal and establishes a communication path based on the selected antenna. The selected antenna involved in the communication path is typically relatively free from degradation in transmission caused by a user's grasp of the mobile device. The radiation property of the mobile device, which may be degraded due to a user's grasp, can exhibit relatively little or no degradation as compared to the typical degradation in performance when the mobile device is being grasped.
