In a laminated chip package, a plurality of semiconductor plates each having a semiconductor device and a wiring electrode connected to the semiconductor device are laminated. On a side surface for wiring of the laminated chip package, an end face of an inner electrode for examination formed inside the side surface for wiring in the semiconductor plate is formed. The laminated chip package further has an outer electrode for examination connecting the end faces of the inner electrodes for examination along a lamination direction of the semiconductor plates, only for two adjacent semiconductor plates among the semiconductor plates.

A magnetic head includes first to third coils, a main pole, a write shield, first and second yoke layers, and first and second coupling parts. The first and second yoke layers are magnetically connected to the write shield. The first yoke layer is located on the leading side relative to the main pole, whereas the second yoke layer is located on the trailing side relative to the main pole. The first coupling part magnetically couples the main pole and the second yoke layer to each other. The second coupling part magnetically couples the first yoke layer and the second yoke layer to each other. The first coil is wound around the first coupling part, whereas the second and third coils are wound around the second coupling part.

A magnetic head includes a shield, and first and second return path sections. The shield has an end face that is located in a medium facing surface to wrap around an end face of a main pole. The shield includes a bottom shield, two side shields, and a top shield. The first return path section includes a yoke layer, and first and second coupling layers that magnetically couple the bottom shield and the yoke layer to each other. The first coupling layer is magnetically connected to the bottom shield. The second coupling layer magnetically couples the first coupling layer to the yoke layer. No end faces of the second coupling layer are exposed in the medium facing surface. The second return path section magnetically couples the top shield and the main pole to each other.

In a ceramic capacitor according to the present invention, an interdiginated pair of internal electrodes are arranged, on a substrate, perpendicular to a surface of the substrate, and a ceramic dielectric member is filled into a gap between this pair of internal electrodes. For this reason, the dimensions of the internal electrodes do not substantially change before and/or after the formation of the ceramic dielectric member, whereby the dimensions formed at the time of internal electrode can be maintained. According to this ceramic capacitor, since the internal electrode dimensions can be easily controlled like this, dimensional control of internal electrode spacing can also be easily carried out.

A method of taper-etching a layer to be etched that is made of SiO2 or SiON and has a top surface. The method includes the step of forming an etching mask with an opening on the top surface of the layer to be etched, and the step of taper-etching a portion of the layer to be etched, the portion being exposed from the opening, by reactive ion etching so that a groove having two wall faces that intersect at a predetermined angle is formed in the layer to be etched. The etching mask is formed of a material containing elemental Al. The step of taper-etching employs an etching gas that contains a main component gas, which contributes to the etching of the layer to be etched, and N2.

A method of manufacturing the plasmon generator includes the steps of: forming a base part made of a dielectric material; forming a metal film that is to later become the plasmon generator; and forming a filler layer made of a dielectric material. The base part includes a base surface and a protruding part that protrudes from the base surface. The protruding part has a top surface that is different in level from the base surface, and a first sidewall connecting the top surface of the protruding part to the base surface. The metal film includes an adhesion part adhering to the first sidewall. The filler layer has a second sidewall disposed such that the adhesion part is interposed between the first sidewall and the second sidewall.
