Method of fabricating a circuit board structure having an embedded electronic element

A method for fabricating a circuit board structure having at least an embedded electronic element, comprising the steps of:

• providing a substrate having opposite first and second surfaces and embedding at least an electronic element in the substrate, wherein the electronic element has a first active surface having a plurality of first electrode pads and a second active surface opposite to the first active surface and having a plurality of second electrode pads, the first active surface and the first electrode pads of the electronic element being exposed from the first surface of the substrate;
• forming a plurality of first conductive bumps on the first electrode pads of the electronic element;
• and
• after the plurality of first conductive bumps are formed on the first electrode pads of the electronic element, covering the first surface of the substrate and the first active surface of the electronic element with a first dielectric layer and a first metal layer stacked on the first dielectric layer, wherein the first conductive bumps penetrate the first dielectric layer so as to be in contact with the first metal layer.
