Abstract: Apparatus and method for monitoring wafer charges are proposed. A conductive pin, a conductive spring and a conductive line are configured in series to connect the backside surface of the wafer and the sample conductor so that the backside surface of the wafer and the surface of the sample conductor have identical charge density. Hence, by using a static electricity sensor positioned close to the surface of the sample conductor, the charges on the wafer may be monitored. Note that the charges appeared on the frontside surface of the wafer induces charges on the backside surface of the wafer. The sample conductor is a sheet conductor and properly insulated from the surrounding environment. As usual, the sample conductor and the static electricity sensor are positioned outside the chamber where the wafer is placed and processed, so as to simplify the apparatus inside the chamber and reduce the contamination risk.

Abstract: A sinusoidal modulation method and a three-phase inverter are disclosed. A pulse driving signal controller is disposed to connect the three-phase inverter. The pulse driving signal controller controls the transistors of the three-arm full-bridge architecture. By examining the phase angle of the output current, operations of the upper and lower bridge power transistors can be adjusted, so that three power transistors are turned on and the other three power transistors are turned off during the PWM operations. As a result, the dead time is not required to set during the PWM operation for preventing a short-circuit due to dynamic switching errors of the upper and lower bridge power transistors. The requirements of the hardware circuits can be also reduced.

Abstract: A method for wireless communication includes the following steps. A silence command is transmitted to a mobile terminal by a network node when a first predetermined condition occurs. A secondary component carrier of the mobile terminal transitions to a silence state from an activation state according to the silence command and a silence-specific configuration, and is operated in the silence state according to the silence-specific configuration. A signaling message is transmitted to the mobile terminal by the network node when a second predetermined condition occurs. The secondary component carrier transitions to the activation state from the silence state according to the silence-specific configuration and restarts or resumes signal transmissions on the secondary cell in accordance with the signaling message.
