Abstract
An inductor pattern is formed on a substrate. A conductive pattern having a concave-convex structure is formed on the inductor pattern to increase a surface area of the inductor pattern. An insulation layer is formed on the inductor pattern. After a groove is formed such that the insulation layer is removed to expose the inductor pattern, a conductive pattern is conformally formed on the groove and the insulation layer. Thus, a surface area of the inductor pattern as well as a thickness of an inductor increases to obtain an inductor of a high quality factor.
