发明名称 Printed circuit board
摘要 A printed circuit board including a conductor portion, an insulating layer formed over the conductor portion, a thin-film capacitor formed over the insulating layer and including a first electrode, a second electrode and a high-dielectric layer interposed between the first electrode and the second electrode, and a via-hole conductor structure formed through the second electrode and insulating layer and electrically connecting the second electrode and the conductor portion. The via-hole conductor structure has a first portion in the second electrode and a second portion in the insulating layer. The first portion of the via-hole conductor structure has a truncated-cone shape tapering toward the conductor portion.
