LC ELEMENT, SEMICONDUCTOR DEVICE AND MANUFACTURE OF LC ELEMENT

摘要

PURPOSE: To provide LC elements and a semiconductor device with a manufacturing method of LC elements which are capable of manufacturing easily and omitting assembling work of components in a post process and forming them as a part of LC or LSI and changing characteristics arbitrarily by changing a capacitor existing like a distributed constant as occasion demands. ;CONSTITUTION: An LC element 100 includes a non-spiral-shaped n⁺ region 22 formed near the surface of a p-Si substrate and further includes a non-spiral- shaped p⁺ region 20 formed partially therein, thereby forming a pn junction layer 26. An electrode 10 is formed on the surface of the p⁺ region 20. Both the electrode 10 and the above-described n⁺ region 22 function as an inductor respectively while the application of the pn junction layer 26 in backward bias forms a capacitor like a distributed constant and provides an excellent damping characteristic.;COPYRIGHT: (C)1996,JPO
