Abstract: A plating apparatus for electroplating a wafer includes a housing defining a plating chamber for housing a plating solution. A voltage source of the apparatus has a first terminal having a first polarity and a second terminal having a second polarity different than the first polarity. The first terminal is electrically coupled to the wafer. An anode is within the plating chamber, and the second terminal is electrically coupled to the anode. A membrane support is within the plating chamber and over the anode. The membrane support defines apertures, wherein in a first zone of the membrane support a first aperture-area to surface-area ratio is a first ratio, and in a second zone of the membrane support a second aperture-area to surface-area ratio is a second ratio, different than the first ratio.

Abstract: A femtocell includes a memory, a transmitter, a receiver and a controller. The memory stores access probability values in different time periods, and a comparison table of power saving rates and probability thresholds. Each power saving rate is a proportion of the time periods whose access probability values are not more than a predetermining probability threshold and all time periods. The controller includes a setting module setting the predetermining probability threshold, a time module getting a current time and a corresponding current time period, a user identifying module determining whether the user accessing the femtocell through the receiver is a registered user, a switching module controlling the transmitter through determining whether the access probability value at the current time period is less than the predetermined probability threshold, a statistic module calculating the access probability value at the current time period according to the identifying result of the user identifying module.

Abstract: A mobile phone power supply circuit for a mobile phone, including a super capacitor, a photovoltaic module, a comparator, a battery power source, and a single-pole-double-throw (SPDT) switch. The photovoltaic module buffers solar power in the super capacitor. The comparator compares voltage of the super capacitor and a reference voltage and outputs a control signal according to the comparison. The SPDT switch selects either the super capacitor or the battery power source to supply power to the mobile phone according to the control signal.
