Integrated inductance structure with high efficiency

The invention provides an integrated inductance structure with high efficiency. The integrated inductance structure comprises a first substrate, a second substrate, first metal line layers embedded in the first substrate, and second metal line layers embedded in the second substrate. The first metal line layers and the second metal line layers are connected in an opposite and staggered mode to be in a solenoid shape through a metal conductor layer. The first metal line layers are electrically connected with the other surface of the first substrate through metal through holes. The integrated inductance structure can achieve larger thickness values of metal lines, and is beneficial to achieve low resistance, meanwhile, large inductance can be achieved through controlling the cross sectional area of a magnetic core, and integrated inductors and transformers of high efficiency are obtained.
