摘要:
The invention relates to a surface mount type electronic component to be mounted on a printed circuit board or a hybrid IC (HIC) and provides a low-cost electronic component which is reliable in terms of heat resistance and pressure resistance. An inductor as the electronic component has a general outline in the form of a rectangular parallelepiped, provided by forming a lead-out electrode having a multi-layer structure on a substrate and forming a protective layer for protecting the lead-out electrode using thin film forming techniques. The lead-out electrode includes a first electrode which is electrically connected to a coil conductor and which has an exposed part exposed on an outer surface and a second electrode which has an exposed part exposed on the outer surface to extend an electrode width different from an electrode width of the first electrode and which is formed directly above the first electrode and electrically connected to the first electrode.

A thin-film device incorporates a device main body and four terminal electrodes. The device main body has four side surfaces. The terminal electrodes are disposed to touch respective portions of the side surfaces. The device main body includes a lower conductor layer used to form a first passive element and an upper conductor layer used to form a second passive element. At each side surface of the device main body, an end face of the lower conductor layer and an end face of the upper conductor layer are electrically and physically connected to each other. The terminal electrodes touch the end faces of the lower and upper conductor layers, and are thereby connected to the lower and upper conductor layers.

A thin-film device includes a substrate, and a capacitor provided on the substrate. The capacitor incorporates a lower conductor layer having a top surface and a side surface; a flattening film disposed to cover the top and side surfaces of the lower conductor layer; a dielectric film disposed on the flattening film; and an upper conductor layer disposed on the dielectric film. The lower conductor layer is composed of an electrode film and a plating film disposed on the electrode film. The dielectric film has a thickness that falls within a range of 0.02 to 1 μm inclusive and that is smaller than a thickness of the lower conductor layer. A surface roughness in maximum height of a top surface of the flattening film is smaller than that of the top surface of the lower conductor layer and equal to or smaller than the thickness of the dielectric film.

A thin-film device incorporates: a substrate; an insulating layer, a lower conductor layer, a dielectric film, an insulating layer, an upper conductor layer and a protection film that are stacked in this order on the substrate; and four terminal electrodes. The four terminal electrodes touch part of end faces of the upper conductor layer, and part of the top surface of the upper conductor layer contiguous to the end faces. The protection film has four concave portions, each of which has a shape that is recessed inward from the edge of the protection film except portions thereof corresponding to these concave portions. The four concave portions expose respective portions of the top surface of the upper conductor layer that touch the four terminal electrodes. The four concave portions accommodate respective portions of the four terminal electrodes.
