ELECTRONIC COMPONENT BASE

摘要

PROBLEM TO BE SOLVED: To provide an electronic component base which enables providing a capacitor onto the upper surface of insulating layers having two or more circuit patterns laterally arrayed at predetermined intervals, or along the lateral direction between the insulating layers, without occupying a large area. SOLUTION: A via-hole 8 filled with a conductor 23 is provided in an insulating layer portion directly below each of circuit patterns 14 which are laterally arrayed at predetermined intervals. Also, a via-hole 8 filled with a ferroelectric material 22 is provided in an insulating layer portion which is located between the via-holes 8 filled with the conductors 23 and between the adjacent circuit patterns 14. Using these ferroelectric material 24 and conductor 23, a capacitor 24 is three-dimensionally provided in the direction of thickness of the insulating layer of the electronic component base.
