    • The present invention relates to a method for manufacturing an inductor being a passive device in RE MEMS, RFCMOS, Bipolor/SiGe and BiCMOS semiconductor devices. According to the present invention, a first negative photoresist layer is covered on a substrate having a lower electrode. A via hole that will become a contact portion of the inductor is then defined by means of an exposure process using a first mask. A second negative photoresist layer is covered on the first negative photoresist layer. Trenches that will become line portions of the inductor are defined by an exposure process using a second mask. A damascene pattern having the via hole and the trenches is formed by means of a developing process and is then buried with copper, thus forming the inductor. Not only a thickness of the trenches in the line portion and a thickness of the via hole in the contact portion can be uniformly controlled, but also their height can be easily controlled. Therefore, that an inductor of a high quality can be manufactured.
    • 本发明涉及一种用于制造在RE MEMS,RFCMOS,双色/ SiGe和BiCMOS半导体器件中的无源器件的电感器的方法。 根据本发明,在具有下电极的基板上覆盖第一负光致抗蚀剂层。 然后将通过使用第一掩模的曝光处理来限定将成为电感器的接触部分的通孔。 第二负光致抗蚀剂层被覆盖在第一负光致抗蚀剂层上。 将成为电感线路部分的沟槽由使用第二掩模的曝光处理限定。 具有通孔和沟槽的镶嵌图案通过显影工艺形成,然后用铜掩埋,从而形成电感器。 不仅可以均匀地控制线部分中的沟槽的厚度和接触部分中的通孔的厚度,而且可以容易地控制其高度。 因此,可以制造高质量的电感器。

    • A feedforward-type linear power amplifier directly compares amplitude and phase of a signal applied to one input end of a first signal canceler with amplitude and phase of a signal applied to another input end of the first signal canceler, and according to the comparison results, controls a first variable attenuator and a first variable phase shifter disposed in a pre-stage of the first signal canceler so that the first signal canceler extracts only the intermodulation distortion signals generated while a main power amplifier amplifies the RF input signal. Then, the linear power amplifier directly compares amplitude and phase of the intermodulation distortion signal on a main path with amplitude and phase of the intermodulation distortion signal on a sub path, and according thereto, controls a third variable attenuator and a third variable phase shifter to cancel the intermodulation distortion signals contained in the RF output signal of the main power amplifier.
    • 前馈型线性功率放大器直接对施加到第一信号消除器的一个输入端的信号的幅度和相位与施加到第一信号消除器的另一输入端的信号的幅度和相位进行比较,并且根据比较结果, 控制第一可变衰减器和设置在第一信号消除器的前级的第一可变移相器,使得第一信号消除器仅提取当主功率放大器放大RF输入信号时产生的互调失真信号。 然后,线性功率放大器直接将主路上的互调失真信号的幅度和相位与子路径上的互调失真信号的幅度和相位进行比较,并且根据该功率控制第三可变衰减器和第三可变移相器 消除主功率放大器的RF输出信号中包含的互调失真信号。
