Abstract: In a method for obtaining the equivalent oxide thickness of a dielectric layer, a first semiconductor capacitor including a first silicon dioxide layer and a second semiconductor capacitor including a second silicon dioxide layer are provided and a modulation voltage is applied to the semiconductor capacitors to measure a first scanning capacitance microscopic signal and a second scanning capacitance microscopic signal. According to the equivalent oxide thicknesses of the silicon dioxide layers and the scanning capacitance microscopic signals, an impedance ratio is calculated. The modulation voltage is applied to a third semiconductor capacitor including a dielectric layer to measure a third scanning capacitance microscopic signal. Finally, the equivalent oxide thickness of the dielectric layer is obtained according to the equivalent oxide thickness of the first silicon dioxide layer, the first scanning capacitance microscopic signal, third scanning capacitance microscopic signal, and the impedance ratio.

Abstract: A blood pressure detection device manufactured by a semiconductor process includes a substrate, a microelectromechanical element, a gas-pressure-sensing element, a driving-chip element, an encapsulation layer and a valve layer. The substrate includes inlet apertures. The microelectromechanical element and the gas-pressure-sensing element are stacked and integrally formed on the substrate. The encapsulation layer is encapsulated and positioned on the substrate. A flowing-channel space is formed above the microelectromechanical element and the gas-pressure-sensing element. The encapsulation layer includes an outlet aperture in communication with an airbag. The driving-chip element controls the microelectromechanical element, the gas-pressure-sensing element and valve units to transport gas.

Abstract: A multimedia player is provided. The multimedia player can be selectively operated in a first mode or a second mode, and includes a plurality of multimedia sources, a USB hub interface, and a processor. The plurality of multimedia sources provides multimedia data when the multimedia player operates in the first mode. The USB hub interface connects to an external electronic device and communicates with the external electronic device when the multimedia player operates in the second mode. The processor couples to the plurality of multimedia sources and the USB hub interface. When operated in a first mode, the processor retrieves and decodes the multimedia data, wherein the decoded multimedia data is ready for presentation. When operated in the second mode, the processor connects to the external electronic device via the USB hub interface. The multimedia sources then serve as USB devices supporting the external electronic device.

Abstract: A multimedia playback system, a FIFO memory system, and a method for storing multimedia data are provided. The multimedia playback system or the FIFO system comprises a FIFO memory and a memory controller. The FIFO memory buffers a first and a second multimedia data. The memory controller allocates the FIFO memory according to allocation information. The first and second multimedia data are synchronous during playback. The allocation information depends on a first throughput rate of the first multimedia data and a second throughput rate of the second multimedia data. The method comprises the following steps: providing a FIFO memory for buffering the first and second multimedia data; and allocating the FIFO memory according to allocation information.
