    Abstract: Embodiments of the present disclosure provide a communication method, apparatus, and system. An information device provided herein may be configured to keep a call record corresponding to the call request, and obtain calling side information (including a number of a calling terminal) from the call record when receiving a first query request sent by a second terminal. The information device may also be configured to send the calling side information to the second terminal. The second terminal may be configured to send the first query request after receiving the call request, and display the calling side information. Thus, when the calling terminal calls a called terminal using the enterprise switchboard, the called terminal can obtain the number of the calling terminal corresponding to the current call and display the number of the calling terminal, that identifies a real calling user based on the number.

  • Publication number: 20190088457
    Abstract: Embodiments presented herein relate to a method of and apparatus for processing a substrate in a semiconductor processing system. The method begins by initializing a pulse synchronization controller coupled between a pulse RF bias generator and a HIPIMs generator. A first timing signal is sent by the pulse synchronization controller to the pulse RF bias generator and the HIPIMs generator. A sputtering target and an RF electrode disposed in a substrate support is energized based on the first timing signal. The target and the electrode is de-energized based on an end of the timing signal. A second timing signal is sent by the pulse synchronization controller to the pulse RF bias generator and the electrode is energized and de-energized without energizing the target in response to the second timing signal.
