Method of manufacturing a component-embedded printed circuit board

A method of manufacturing a component-embedded printed circuit board, the method comprising:

• mounting a component on a first copper foil having a first circuit pattern formed thereon, such that the component is electrically connected with the first circuit pattern;
• after mounting the component, stacking an insulation layer, the insulation layer having a cavity, on to a second copper foil, the second copper foil having at least one conductive protrusion formed thereon, such that the conductive protrusion penetrates upper and lower surfaces of the insulation layer;
• after stacking the insulation layer, stacking together the first copper foil and the second copper foil such that the component is embedded in the cavity and the first copper foil and the second copper foil are electrically connected by the conductive protrusion;
• and
• after stacking together the first copper foil and the second copper foil, removing the first copper foil except for the first circuit pattern such that the first circuit pattern is buried in the insulation layer, and removing a portion of the second copper foil such that a second circuit pattern is formed on the insulation layer,
• wherein the removing only includes
• stacking a photosensitive film on the second copper foil;
• removing a portion of the photosensitive film;
• and
• removing portions of the exposed first copper foil and second copper foil to form the circuit patterns by etching.
