Abstract
An LC element for use with a semiconductor device features excellent attenuation characteristics. The element includes a pn junction that has a predetermined shape and which is formed near the surface of a semiconductor substrate. The predetermined shapes include a spiral shape, a meander shape, a straight shape, and a curved shape. An inductor electrode is formed on the pn junction, and the pn junction is reverse biased with a specified voltage to form a distributed capacitor having a desired capacitance. One of the p and n layers functions as an inductor. The element is easily manufactured and requires minimal assembly, and may also be integrally formed as part of an IC or LSI device.
