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.

A cut resistant and flame-retardant fabric-like material. A plurality of guardplates are made of a flame-retardant material and resin is affixed to a fabric substrate to provide a fabric-like material with superior cut resistant and flame-retardant properties. An optional second plurality of guardplates can be affixed to substrate opposite a first layer of guardplates. Also, an optional layer can be disposed over the guardplates to add another property to the fabric-like material such as heat or abrasion resistance, grip, or additional flame retardance.

The present invention provides a record media, and more particularly, to a method of recording disc identification information within a management area of a recordable optical disc and an optical disc recording/reproducing method using the same. In recording optical disc identification information within a disc management area, the present invention includes recording a media type identification information identifying a type of a record media of an optical disc and a disc manufacturer identification information identifying a manufacturer of the optical disc, respectively. Accordingly, the present invention provides various specified methods of recording disc identification information within a management area in a high-density optical disc, thereby enabling to efficiently cope with the recording/reproducing of the optical disc using the recorded identification information.
摘要:
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.
