Abstract: A semiconductor device includes a first region and a second region, and the second region surrounds the first region. The semiconductor device includes at least one electronic unit, a redistribution structure, a plurality of first pads, and a plurality of second pads. The redistribution structure may be electrically connected to at least one electronic unit. A plurality of first pads are arranged on the redistribution structure and correspondingly to the first region. There is a first pitch between two adjacent first pads. A plurality of second pads are arranged on the redistribution structure and correspondingly to the second region. There is a second pitch between two adjacent second pads, so that the first pitch is smaller than the second pitch.

Abstract: Electrostatic discharge (ESD) structures are provided. An ESD structure includes a semiconductor substrate, a first epitaxy region with a first type of conductivity over the semiconductor substrate, a second epitaxy region with a second type of conductivity over the semiconductor substrate, and a plurality of semiconductor layers. The semiconductor layers are stacked over the semiconductor substrate and between the first and second epitaxy regions. A first conductive feature is formed over the first epitaxy region and outside an oxide diffusion region. A second conductive feature is formed over the second epitaxy region and outside the oxide diffusion region. A third conductive feature is formed over the first epitaxy region and within the oxide diffusion region. A fourth conductive feature is formed over the second epitaxy region and within the oxide diffusion region. The oxide diffusion region is disposed between the first and second conductive features.

Abstract: A power switch module for an electronic device includes a flip-flop circuit, a first current path for coupling a voltage source to the flip-flop circuit, and a second current path for coupling the voltage source to the flip-flop circuit. In response to a user power-on event, an output of the flip-flop circuit is at a first logic state for normally powering on the electronic device. In response to a user power-off event, the output of the flip-flop circuit is at a second logic state for normally powering off the electronic device. When the voltage source is suddenly interrupted, the output of the flip-flop circuit is kept at the first logic state but the electronic device is abnormally powered off. After the voltage source is resumed, the output of the flip-flop circuit kept at the first logic state reboots the abnormally powered-off electronic device.

Abstract: In a cellular phone having a memory with a data base for storing a time conversion table regarding time of one place in the world belonging to a first telephone system and corresponding time of the other place in the world belonging to a second telephone system different from the first one, a method for automatically adjusting a time difference between the cellular phone and a connected base station during an international roaming comprises the steps of when a CPU of the cellular phone determines that an associated telephone system is different from that of the connected base station, the telephone system accessing the data base and looking up the conversion table for retrieving a corresponding time of the connected base station with respect to the cellular phone; and showing the corresponding time as a local time on a display of the cellular phone.

Abstract: The present invention provides a method for switching between multiple SIM cards within a telephone. The method comprises the steps of storing a plurality of internal ID codes, each of which identifies a direct service provider of one of the SIM cards, receiving an ID code identifying one of the service providers, comparing the received ID code to each of the internal ID codes, and switching to one of the SIM cards when the service provider identified by the received ID code is recognized as the direct one of the SIM card switched to, identified by the corresponding internal ID code.
