Chip-component structure and method of producing same

摘要

In a chip-component structure, a monolithic ceramic capacitor is a structure including a predetermined number of substantially flat internal electrodes stacked on each other. An interposer includes a substrate larger than the outer shape of the monolithic ceramic capacitor. The substrate includes a first major surface on which first front electrodes for use in mounting the monolithic ceramic capacitor are disposed and a second major surface on which first back electrodes for use in connecting to an external circuit board are disposed. The interposer includes a depression in its side surface. The depression includes a wall surface on which a connection conductor is disposed. The front surface of the substrate is overlaid with resist films extending along its edges.

1. A chip-component structure comprising:
a substrate including parallel or substantially parallel front and back surfaces and four side surfaces extending is a direction perpendicular or substantially perpendicular to the front and back surfaces, the front and back surfaces being opposed to each other in the direction perpendicular or substantially perpendicular to the front and back surfaces; a first front electrode disposed on the front surface of the substrate and adjacent to a first one of the four side surfaces of the substrate; a second front electrode disposed on the front surface of the substrate and adjacent to a second one of the four side surfaces of the substrate, the second side surface being parallel or substantially parallel to the first side surface; a first back electrode disposed on the back surface of the substrate and opposed to the first front electrode; a second back electrode disposed on the back surface of the substrate and opposed to the second front electrode; a chip-component mounted on the front surface of the substrate, including a first external electrode connected to the first front electrode and a second external electrode connected to the second front electrode; a first connection conductor disposed in a side portion or in a corner of the substrate and electrically connecting the first front electrode and the first back electrode; and a second connection conductor disposed in a side portion or in a corner of the substrate and electrically connecting the second front electrode and the second back electrode; wherein each of the first front electrode and the second front electrode is overlaid with a protective film, and the protective film is disposed partially or completely on edges of the first front electrode and the second front electrode along at least one of the side surfaces.
