A method for manufacturing a printed circuit board with a capacitor embedded therein which has a dielectric film using laser lift off, and a capacitor manufactured thereby. In the method, a dielectric film is formed on a transparent substrate and heat-treated. A first conductive layer is formed on the heat-treated dielectric film. A laser beam is irradiated onto a stack formed, from below the transparent substrate, to separate the transparent substrate from the stack. After the transparent substrate is separated from the stack, a second conductive layer is formed with a predetermined pattern on the dielectric film. Also, an insulating layer and a third conductive layer are formed on the first and second conductive layers to alternate with each other in a predetermined number.

The invention relates to a fabrication method of a composite metal oxide dielectric film containing at least two metallic elements on a substrate, and a composite metal oxide dielectric film fabricated thereby. The method includes: forming an amorphous film containing at least one of the metallic elements; preparing a hydrothermal solution where a precursor of the remaining element of the metallic elements is mixed; immersing the amorphous film into the hydrothermal solution; and hydrothermally treating the amorphous film so that the remaining one of the metallic elements is synthesized to the amorphous film, thereby forming a crystallized composite metal oxide film.
