Embodiments describe the selective electroless plating of dielectric layers. According to an embodiment, a dielectric layer is patterned to form one or more patterned surfaces. A seed layer is then selectively formed along the patterned surfaces of the dielectric layer. An electroless plating process is used to deposit metal only on the patterned surfaces of the dielectric layer. According to an embodiment, the dielectric layer is doped with an activator precursor. Laser assisted local activation is performed on the patterned surfaces of the dielectric layer in order to selectively form a seed layer only on the patterned surfaces of the dielectric layer by reducing the activator precursor to an oxidation state of zero. According to an additional embodiment, a seed layer is selectively formed on the patterned surfaces of the dielectric layer with a colloidal or ionic seeding solution.

Then, a first dielectric layer is formed on the carrier and the first circuit layer. Thereafter, at least one first hole is formed in the first dielectric layer to expose a portion of the first circuit layer. Then, a second dielectric layer is formed on the first dielectric layer and the first circuit layer. Thereafter, at least one trench and at least one second hole are formed in the second dielectric layer, in which the trench exposes a portion of the first dielectric layer, and the second hole exposes the portion of the first circuit layer. The second hole is disposed in the first hole. Then, a metal layer is formed to fill the trench and the second hole.

A manufacturing method of a circuit board is provided. A circuit substrate having a first surface and at least a first circuit is provided. A dielectric layer having a second surface and covering the first surface and the first circuit is formed on the circuit substrate. The dielectric layer is irradiated by a laser beam to form a first intaglio pattern, a second intaglio pattern and at least a blind via. A first conductive layer is formed in the first intaglio pattern, the second intaglio pattern and the blind via. A barrier layer and a second conductive layer are formed in the second intaglio pattern and the blind via. Parts of the second conductive layer, parts of the barrier layer and parts of the first conductive layer are removed until the second surface of the dielectric layer is exposed, so as to form a patterned circuit structure.

Disclosed are apparatus and methods for a magnetic component. In accordance with an embodiment, a magnetic component comprises a base substrate defining a winding cup having a shape of a closed groove surrounding a hub. The winding cup defines a core space operable to receive a core therein. A first conductive pattern is disposed on at least a portion of the base substrate including the winding cup. A second substrate defines a second conductive pattern. The second substrate is coupled to the first base surface with the first conductive pattern in operable alignment with the second conductive pattern. The first and second conductive patterns are coupled in electrical communication so as to define one or more winding-type electric circuits surrounding the core space so as to induce a magnetic flux within the core space when the one or more electric circuits are energized by a voltage source.

A method of manufacturing a substrate structure is provided. An insulation substrate having an upper surface is provided. A portion of the upper surface of the insulation substrate is irradiated by a first laser beam so as to form a first intaglio pattern. The first laser beam is IR laser beam or fiber laser beam.

A first metal layer is formed on the upper surface of the insulation substrate, and covers the upper surface of the insulation layer and the modification surface of the first intaglio pattern, and fills up the first intaglio pattern. A grinding process is performed on the first metal layer so as to expose the upper surface of the insulation substrate and define a first patterned circuit layer. A first upper surface of the first patterned circuit layer is aligned with the upper surface of the insulation substrate.
