AI summary

A manufacturing method of an integrated driving module with energy conversion function includes providing a carrier board and forming an integrated electromagnetic induction component layer having a first dielectric layer, a plurality of conductive coil layers and a plurality of conductive connecting components on a surface of the carrier board. A patterned conductive circuit layer is formed on the integrated electromagnetic induction component layer, and electrically connecting to each other through the conductive connecting components. An embedded electrical component is patterned on the patterned conductive circuit layer. A conductive component is disposed on the patterned conductive circuit layer. Thereafter, the method forms a second dielectric layer to cover the embedded electrical component and the conductive component and removes the carrier board to form a plurality of integrated driving modules.
