    Abstract: Disclosed are an embedded capacitor and a printed circuit board including the same that can minimize the oxidization of a metal layer. A thin-film capacitor can include a first metal electrode film; a barrier layer, formed on the first metal electrode film to include a conductive oxide; a dielectric film, formed on the barrier layer; and a second metal electrode film, formed on the dielectric film. With the present invention, the outstanding characteristic of a ferroelectric thin film can be provided by minimizing the oxidization of a copper film in the heat treatment after forming the ferroelectric thin film on the copper film.
