Abstract: A method of cleaning a silicon nitride layer on a substrate is provided to effectively remove negative-charged impurities such as polymer and particle from the silicon nitride layer. In the method, the zeta potential of the silicon nitride layer is changed from positive to negative, and then the silicon nitride layer is cleaned with a first solution selected from an alkali solution and an NC-2 solution. So the negatively-charged impurities can be easily removed due to a repulsion force. The substrate can be treated with spin scrubber or quick dump rinse before and/or after the changing of the zeta potential. To change the zeta potential, the substrate can be dipped into a second solution such as an SC-1 solution, an NC-2 solution, and an alkali solution.

Abstract: There is provided a PTS (Partial Transmit Sequence) OFDM (Orthogonal Frequency Division Multiplexing) scheme for reduction of a PAPR (Peak-to-Average Power Ratio). In an OFDM transmitting apparatus for peak power reduction according to the present invention, an rotational sub-block partitioner partitions an input data block of length N into M, the number of sub-block, and distributes the partitioned data of each data block in M sub-blocks one by one rotationally. M IFFTs (Inverse Fast Fourier Transformers) perform N/M-point IFFT on N/M data assigned to each of the M sub-blocks and M coefficient multipliers multiply the N/M data output from each IFFT by a predetermined coefficient to give orthogonality to the frequency components of the N/M output data. A phase factor optimizer optimizes M phase factors to minimize a PAPR using the N/M output values of each coefficient multiplier. M multipliers multiply the optimized M phase factors by the outputs of the coefficient multipliers.

Abstract: A temperature sensing oscillator circuit generates a pulse signal whose cycle is changed by temperature change. The temperature sensing oscillator circuit comprises a temperature sensing pulse generating unit and a pulse width regulating unit. The temperature sensing pulse generating unit changes an operating power supplied to an oscillator depending on temperature change to generate a pulse signal having a cycle varied depending on the temperature change. The pulse width regulating unit regulates a pulse width of a pulse signal outputted from the temperature sensing pulse generating unit. As a result, since the operating power of the oscillator is varied by temperature change, the configuration of the circuit is more simplified, and a refresh signal is stably generated at low temperature without additional signals.
