Abstract: A single-phase bridgeless insulated power factor adjustment circuit includes an EMI filter module, low-frequency switching diode module, two switches and two insulated voltage transformation modules. The EMI filter module is coupled to an AC power. The low-frequency switching diode module is coupled to the EMI filter module. The two switches are coupled to the low-frequency switching diode module. The two insulated voltage transformation modules are coupled to one of the two switches. With the low-frequency switching diode module being in first ON state, one of the two switches turns on, and one of the two insulated voltage transformation modules turns on. With the low-frequency switching diode module being in second ON state, the other switch turns on, and the other insulated voltage transformation module turns on. Hence, the circuit is unlikely to fail, but features simple circuitry, incurs low costs, be compact, and achieves high conversion efficiency.

Abstract: An adaptive digital pre-distortion system includes a transmitting module and a receiving module. The transmitting module is configured to receive a first signal and includes a modulator, pre-distortion module, and transmitting circuit. The pre-distortion module is coupled to the modulator to perform a pre-distortion operation in accordance with the first modulation signal and generate a first pre-distortion signal. The transmitting circuit generates a first transmitted signal in accordance with the first pre-distortion signal. The receiving module is configured to receive the first transmitted signal and includes a receiving circuit, demodulator, and prediction module. The prediction module generates a pre-distortion parameter in accordance with a modulation vector error between the second demodulation signal and the first signal and transmits the pre-distortion parameter to the pre-distortion module, wherein the pre-distortion module adjusts the pre-distortion operation of the pre-distortion module in accordance with the pre-distortion parameter.

Abstract: Disclosed is an aluminum nitride electrostatic chuck, comprising: a positioning electrostatic chuck and a carrier structure. The positioning electrostatic chuck includes a groove structure layer, a dielectric insulation layer, and a heat conduction layer. In the groove structure layer on the surface of the electrostatic chuck is provided with cooling gas channels, to facilitate control of the temperature distribution of a wafer. The electrostatic chuck is especially designed for use in a semiconductor manufacturing process of high temperature and high plasma power density. The dielectric insulation layer is provided with embedded electrodes, such that voltage conversion can be carried out to effect wafer absorption/release. The cooling gas channels are used to control temperature of the absorbed wafer, by means of heat conduction of aluminum nitride electrostatic chuck. Therefore, wafer temperature distribution is controlled through aspect ratio and geometry of cooling gas channel.

Abstract: Epoxy/MMT composite material and a crosslinking method for epoxy/MMT composite material with second order nonlinear optical properties are introduced. Chromophore-containing intercalating agents are applied to modify montmorillonites (MMTs) to form organoclays by an ion-exchange process, wherein the chrmophores are neatly packed on exfoliated epoxy/organoclay nanocomposites. As a result, optical nonlinearity, i.e. the Pockels effect is observed for the nanocomposites without resorting to the poling process due to self-assembly process. Furthermore, a series of epoxy/MMT nanocomposites comprising thermally reversible furan-norbornene Diels-Alder adducts are prepared to establish a crosslinking feature. Self-alignment behavior, electro-optical (EO) coefficient and temporal stability of the epoxy/MMT nanocomposites are improved by the Diels-Alders crosslinking.
