    Abstract: A received signal is converted into a digital signal through an A/D converter and then converted into the polar coordinate system. A synchronizer removes a frequency offset from the digital signal, the digital signal is again converted into an orthogonal coordinate system and a fast fourier transform is performed with a FFT. The digital signal is again converted into the polar coordinate system. An equalizer and a phase compensator compensate respectively a channel distortion and a phase error to the digital signal. Thus, the OFDM receiver using polar coordinate system and method thereof of the present invention can reduce the number of adders and multipliers required in a frequency synchronization, a compensation for channel influence, and a removal of remaining phase error by processing the signal in the polar coordinate system, thereby simplifying the calculation process and the receiver.

    Abstract: A substrate for a microelectronic device is divided into at least two regions and a boundary region therebetween. The boundary region includes a first portion and a second portion. The boundary region may have subregions having equal area, and the sub-regions are arranged in a matrix shape to form the first portion and the second portion A photoresist is coated on the substrate. Portions of the photoresist on the first region and the first portion is exposed to light through a mask for photolithography, and other portions of the photoresist on the second region and the second portion is then exposed to light through the mask. The area of the sub-regions of the first portion in a column becomes larger as goes to the first region, while that of the second portion becomes smaller.

    Abstract: The present invention relates to an improved method of manufacturing pads of a display panel. Al or Al alloy is deposited and patterned on a glass substrate for forming a plurality of gate electrodes and lines. Then a plurality of pads are formed with Ta or Ti, which is capable of forming an anodic oxide thereof; each pad extending over an edge of each of the respective gate lines to provide an electrical coupling therebetween. Thereafter, the entire surface of the pads, gate electrodes and lines is subjected to an anodic oxidation under a high anodization voltage. Anodic oxide layers on the pads are then etched away together with a silicon nitride layer during a subsequent pad opening processing step. Consequently, in accordance with the invention, a photoresist masking process for the selective anodic oxidation of Al gate lines and electrodes is eliminated.
