摘要： The present invention relates to a wafer formed with an evaluation element and capable of improving productivity and a manufacturing method of an electronic component using the same. In a wafer according to the present invention, a plurality of elements connected to electrode films through lead-out conductive films are arranged and a chip area is defined for cutting out the plurality of elements in a given number. In the wafer, at least one evaluation element is formed in an area outside the chip area. The lead-out conductive films extend to the outside area and are connected to the evaluation elements. With this wafer, since the lead-out conductor is shared between the element and the evaluation element, the electrode film connected therewith can be shared, too. Accordingly, evaluation can be performed by using the evaluation element without the need of providing the wafer with a lead-out conductor and an electrode film exclusively for the evaluation element, so that the chip area to be cut out from the wafer can be made larger than before.

摘要： Provided is a thin-film magnetic head in which the magnetic spacing can be appropriately controlled by dynamically and accordingly, by adjusting the pressure working between the thin-film magnetic head and the magnetic recording medium according to the change of conditions such as the change over time. The thin-film magnetic head comprises at least one cavity for adjusting a pressure working between the thin-film magnetic head and the magnetic recording medium, provided in a surface of the head opposed to the magnetic recording medium, and a volume of the at least one cavity being variable. When the magnetic recording medium passes through near the cavity, the cavity generates a (negative) pressure that attracts the head and the medium toward each other. The amount of the negative pressure depends on the volume of the cavity; thus, a magnetic spacing dMS can be controlled dynamically and accordingly by adjusting the volume.
