A Hall-Effect measure apparatus comprises a magnetic source, a wafer on a thermal chuck, a dc current source and a voltage meter. The magnetic source generates a magnetic field in a perpendicular position relative to the wafer. Furthermore, the magnetic field is targeted at a specific region of the wafer to be tested. By performing a Hall-Effect measurement and van der Pauw measurement, the carrier mobility of the specific region of the wafer can be calculated.

A three-dimensional glasses including a glasses main body, a touch control circuit, a first and a second touch sensing interfaces, a glasses circuit system and a power supplying module is provided. The glasses main body has a first and a second sensing portions. The touch control circuit and the glasses circuit system are disposed in the glasses main body. The first and the second touch sensing interfaces are disposed at the first and the second sensing portions, electrically connected to the touch control circuit, and respectively transmit a first and a second input signals to the touch control circuit. After the touch control circuit receives the first and the second input signals, the touch control circuit transmits a power supplying signal to the power supplying module to drive the power supplying module to supply power to the glasses circuit system. Besides, a power supplying method is also provided.

A serial port connector with power output function includes a serial port having a plurality of pins. Under the existing EIA-RS-232, EIA-RS-422, and EIA-RS-485 standards for connectors, the definition of the pins of the serial port are altered, so that a pin that was originally defined as floating or for serial data communication signal is now changed to a power output specification. Thus, when the connector is connected via the same one cable to a serial port peripheral device, the connector can provide both functions of serial data communication signal transmission and power transmission to thereby largely increase the usability of the connector.

The invention provides a lateral double-diffused metal oxide semiconductor (LDMOS). The pre-metal dielectric layer (PMD) of the LDMOS is a silicon rich content material. Additionally, the inter-layer dielectric layer (ILD), inter-metal dielectric layer (IMD), or protective layer of the LDMOS may be formed of a silicon rich content material.

A lead frame structure is provided, which includes a die pad having a first mounting portion and a second mounting portion separated from the first mounting portion by a gap. The first and second mounting portions are formed with corresponding blocking surfaces bordering the gap, so as to allow a flow rate of an encapsulating resin flowing through the gap during a molding process to be reduced by the blocking surfaces, such that different portions of the encapsulating resin respectively flowing above, in and below the die pad can have substantially the same flow rate, thereby preventing bonding wires from being deformed to cause short circuit and avoiding formation of voids. A semiconductor package with the lead frame structure is also provided.

A PCI-based interfacing device with mappable port addresses to legacy I/O port addresses has an addressing circuit, a PCI controller connected to the addressing circuit and a PCI port, and an equipment controller connected to the PCI controller and an equipment port. The addressing circuit sets up a legacy I/O port address. The PCI controller transmit and receive data packets having data and one of the set of legacy I/O port addresses encapsulated therein to be processed to and from the PCI port, and output the received data packets to the equipment controller. The equipment controller converts the data packets into equipment data corresponding to the equipment port, and transmits the equipment data to the equipment port. Accordingly, the PCI-based interfacing device can perform data communication with legacy I/O port addresses.
