    Abstract: A method of forming a metal pattern on a display substrate includes blanket depositing a copper-based layer having a thickness between about 1,500 Å and about 5,500 Å on a base substrate, and forming a patterned photoresist layer on the copper-based layer. The copper-based layer is over-etched by an etching composition containing an oxidizing moderating agent where the over-etch factor is between about 40% and about 200% while using the patterned photoresist layer as an etch stopping layer, and where the etching composition includes ammonium persulfate between about 0.1% by weight and about 50% by weight, includes an azole-based compound between about 0.01% by weight and about 5% by weight and a remainder of water. Thus, reliability of the metal pattern and that of manufacturing a display substrate may be improved.

    Abstract translation: 在显示基板上形成金属图案的方法包括：在基底基板上铺设厚度在约至约为500埃之间的铜基层，并在铜基层上形成图案化的光致抗蚀剂层。 通过含有氧化调节剂的蚀刻组合物对铜基层进行过蚀刻，其中过蚀刻因子在约40％至约200％之间，同时使用图案化的光致抗蚀剂层作为蚀刻停止层，并且其中蚀刻组合物 包括约0.1重量％至约50重量％的过硫酸铵，包括约0.01重量％至约5重量％的唑类化合物和剩余的水。 因此，可以提高金属图案的可靠性和制造显示基板的可靠性。

    Abstract: Disclosed is an apparatus and method for reducing a peak-to-average power ratio (PAPR) due to multiple subcarriers in an OFDM (Orthogonal Frequency Division Multiplexing) mobile communication system. In the OFDM mobile communication system, a transmitter pre-emphasizes an output signal of an IFFT (Inverse Fast Fourier Transform) block, and a receiver de-emphasizes a received signal before FFT (Fast Fourier Transform), thereby efficiently reducing PAPR due to multiple subcarriers.
